People have been begging for 5:3 for a while, and then it just shows up

#

Have one. Screen is great. Buttons are stiff. Stripped a screw just trying to open it up. Lol. But I'll eventually drill it out and put it back together 😆

hoary cedar
#

It is quite stiff yea, probably needs a rubber swap

#

My d-pad used to be as stiff but got softer not sure how kek

unborn marsh
#

Haha. Maybe I just need to break mine in. Wanted to get a pic of the internals and ended up bending the back out of the way. So without drilling it out it's basically unplayable

Stiff and able to break it in isn't the worst situation

Ah made me panic I don’t have torx 🤣

#

haha, yeah, i come from the custom keyboard world, so i have torx and hex all over

#

those guys

#

almost impossible to strip, wish more companies used them, or at least hex at a minimum

robust ridge
#

Well, no hex plz

hoary cedar
#

anbernic uses hex

robust ridge
#

I have RG351V and a hex driver

unborn marsh
#

i mean philips + chinesium = strip

robust ridge
#

Its hex screws can strip too

hoary cedar
#

They go round 😀

unborn marsh
#

i always assume whenever i take one of these part i'm stripping it, and that's being slow and methodical, lol

#

Torx probably is better

unborn marsh
#

it offers the best grip on shit metal

robust ridge
#

I think I once encountered broken torx holes too

unborn marsh
#

yeah, it can def happen

robust ridge
#

If metal is too soft

#

No screw slot shape can help

unborn marsh
#

it's just the least likely, but somehow they make screws out of something softer than aluminum so shrug

#

you can tell when you drill them out, and you almost go through the whole system with barely any pressure kekdoge

That would be next level shit to release a retrohandheld with mystery scraped off chip and impossible screws 🤣

robust ridge
#

I don't really like having all the different screw slots

#

My everyday carry has a screwdriver

#

It's not magnetized which means one day I'll change it out

#

The one currently has phillips

unborn marsh
#

eh, they have their place

robust ridge
#

The moral of the story

#

Use harder metals plz

unborn marsh
#

like when doing small hardware with small screws you really should be using hardened steel with a good head shape, like philips and flathead is fine for like farming machinery, lol

#

but they're just scheap

#

it's easy to machine, pretty sure on softer metals they just stamp the philips pattern in

#

it wouldn't matter if when putting these together they didn't torq the shit out of them, but it is what it is

unborn marsh
#

well these worked, just some steel M2 8mm screws i had lying around, tightened up nice, can now open it XD

hoary cedar
#

They do 🤣

Ok, so I am not sure what your issue is. But if I were you I would download the emuelec image for the k36 hosted at miraheze (preferably the one uploaded by aeouluuX), flash it into a new card, and manage to then replace the emuelec partition files with the ones on your og card (and then copy the roms to the eeroms partition). The problem with this is thay you will need to keep the extlinux folder from the k36 image, and the files there make reference to a dtb with a different name. So you might have to either rename the dtb or edit the files in the extlinux folder with the dtb file name of the og U8. If you are new to RH it might be a bit too complicated.

quick ravine
#

Ok, so I just tried. You have to copy the entire emuelec partition from your og card except the extlinux folder files. And you have to edit the exlinux folder files with the correct dtb name.

I really appreciate your help! 🙏But this method didn't work for me. When I try to turn the device on. Nothing happens. Not even a light shows up.

my steps were:

copy all the files except the extlinux folder to the partition
copy the "rfk38g3sa.dtb" file to the partition than rename it to "rk3326-evb-lp3-v12-linux.dtb". Then boot the sd card on the device.
This didn't work so copied the dtb file again without changing the name. And then edited the .conf files in the extlinux folder in notepad to change the line to "FDT /rfk38g3sa.dtb."

#

I also tried the ArkOS install method by flashing it on my SD card and replacing the dtb file with the one provided in the old thread. It boots but with the weird rotated screen issue.

I might just let this thing stay a "paperweight" right now until Ark or something is released for it. I guess this is the "danger" of buying a new handheld without a lot of community support yet 😆

I might have figured out the retroarch issue so if all goes well ArkOS will be up tonight 🙂

Ok. So i think you got a step wrong. 1) flash the image 2) delete all contents from the emuelec partition except the extlinux folder 3) copy all files from the emuelec partition of the og card (except exlinux folder) to the new flashed emuelec partition 4) open the files in the the exlinux forlders and renaname the dtb mentions (from rk3326.... to rfk...). 5) rename the file in the exlinux folder called rk3326.....config to rfk38.....config. This way you will have the OG card files and the extlinux files will be redirecting to the right unit partitions.

#

At first it might seem like it isnt loading because it doesnt show the boot images

#

I am guessing that if once you get it to work you delete all the storage contents, then on the next load it will copy all the og files from the system file.

AeolusUX brings new life to another device!

#

power button sleep works only 1 time and it returns black screen after that. i tried various combination with dsi,format/lane and clock-frequency, only the original(emuelec) values make sleep work again (dis,format=<0x00> / dis,lanes=<0x02> / clock-frequency = <ox1c9c380>. but it makes the screen 66hz instead.

I’ll try and return the frequency. Damn I thought it was because its a 351p clone 🤣

and right stick is inverted(it's not important tho). do you know how to invert axis on arkos-mod? 'invert-absx/y/rx/ry' doesn't work here

Just received 2 U8's. IMHO some very disappointing build-quality on both my units. Some buttons barely register, unless you ram down on the them. Dpad's same issue. These buttons are far worse than any other retro handheld that I have owned or used.. 😦

I guess I will be returning both units. I'm okay with doing software tinkering. But having to tear down a device physically, just to make it playable.. Well that kind of takes the fun out of it for me.

Think that's not a conditional thing. They're just hard to actuate compared to any other device I've used. Can maybe fix it by replacing the membrane?

unborn marsh
#

Haha. True that. I mean it's playable for me. But def not as nice as other more expensive devices in this one regard

#

Id also call them not comfortably rounded. They have an edge to them that may be the reason you really have to push down from the top to get them to trigger

Hi everyone I have a U8 and yesterday when I inserted the second TF2 sd I get the error that it does not detect systems. the sd is not corrupted and I saw that in storage/.config/emulationstation/es_systems.cfg there is the folder that goes to read and it is /storage/roms where I inserted a game for psx and it worked. But the point is that before having inserted I did not need this because I have a much larger partition called eeroms, with all my roms, which is no longer read. which I decide to remount it in autostart.sh and custom-start.sh but nothing, it does not even create the logs. So I try with symbiotic links but nothing.. I do not know what to do anymore and I would like to understand how to manage the situation. So I can install Arkos thanks to you but I would also like to recover the original stick, in case you have a backup? Or can you explain to me what is happening? thanks a lot

I've kept an eye on this handheld because of the screen size and price but was put off because it's the same size as an TSP. Would anyone recommend this over a TSP for GBA?

If the 34xx wasn't 70 I would get that. I am looking for the cheapest GBA machine. Currently I'm using the A30 for gba but it doesn't feel good. The TSP is good but too squeaky. I have verticals but would prefer horizontals

Cheapest I can find u8 shipped is $30... Tsp is $55. They're much different price points. Compare U8 with batlexp or r36s

I know the tsp is much more expensive, everyone was comparing it to the u8 so I just wanted to point out the price gap

you can almost buy 2 u8s for the price of a tsp

Yeah early bird price is when new retailers carry a thing they set the price low to get purchase numbers up. You're sorta taking a risk that it's a scam but also it really does happen for most retailers and since the U8 is a bit obscure it's probably legit.

There were a ton of $10 U8's a few weeks ago as all the retailers started carrying them

I actually ordered an early bird g350 yesterday, but the price only dropped to 35 euros. I waited till the last moment hoping for a U8 situation.

hearty iron
hearty iron
#

I couldn't find one for that price when I ordered mine just last week, I got mine RIGHT in between sales 😔 but I am not regretting paying 33 for it, it's well worth it

#

my observations from my very brief handling:

that startup time is REAL slow, like I think it might even be slower than the m17 was, but hey at least it has a sleep mode unlike the m17

it did NOT wanna power back off once I turned it on lol, had to hold it down like 6 times for it to work (and like 8 seconds at that when it did)

it has the most groovy menu music of any handheld I've owned up to this point. seriously, it's SOOO fun to listen to.

it has a pretty solid screen, build quality isn't bad either but the way the screen sticks out definitely concerns me

it's a LOT bigger than I thought it would be, I am not complaining tho, I will have no issues seeing the games I play. I gotta test it out more tho for sure

#

also replacing the sd card with one that is branded might solve the issues of load times

#

this is also my first handheld with 2 sd card slots, how does the second one normally work?

final saffron
hearty iron
#

is there any particular benefit to having 2 slots versus one?

#

other than having more game storage lol, which would be great but for something low end like the u8 idk if it's worthwhile in that regard, a 128gb card (256 at most) should house every gme this thing can run most likely

#

and I can attest, these buttons are STIFF, not as bad as I thought they'd be, but definitely stiff

#

might be able to break them in tho

final saffron
#

If you ever do want to upgrade your OS, it can be really nice having a games card. Often new OS installs prefer a wiped card and then you lose all your save games.

hearty iron
#

that's true, although I normally do sd card copies on my computer as well, but I see the convenience in having a game card

hearty iron
#

I can more or less confirm that the buttons WILL become less stiff over time, I had to do some minor button mashing but my B button has gone from almost unplayably stiff (I didn't realize how bad it was until I tried to play mario world) to quite usable but still a bit hard

#

it's still a bit rough but not NEARLY as bad, if anyone is having stiffness issues, just mash the buttons a bit, honestly test your might in mortal kombat might be amazing for this LOL

#

Yea mine feels like my r36s now lol

hearty iron

is there anything you did to speed up the process? so I can just get it the rest of the way there

hoary cedar
#

Nothing drastic I just played with them

hearty iron
#

might be device lottery then, I've fumbled with mine a bit

#

they are a lot less stiff but I'm having issues actually triggering the membranes underneath

quite a few missed inputs there

quick ravine
hearty iron
#

oooo that's not bad at all, although I don't really want another rk3326 device unless it goes super low just because I already have two of them

final saffron
#

I've taken quite a few consumer electronics apart in my life, but I was not at all prepared for the fragility and low quality of an r36s. I'll be extra careful cracking open the u8

hearty iron
#

I definitely would be, since I always heard that the r36s has solid build quality. I remember I took apart an x7 a while back and it was the worst thing I've taken apart easily

#

I never could get the shoulder buttons back in properly afterwards bc they were held in with small pieces of plastic

#

but I hope that the r36s is a huge step above an x7 in build quality like it is in every other way

#

and I hope that the u8's experience in disassembly goes well, definitely update us here. it feels pretty solid in the hand so I imagine it will

@hoary cedar Hey, I'm working on a super weird bug with the mouse on rotated-screen devices. When you fix the screen on the U8 do you include stuff that remaps mouse directionality too?

Iirc, that was in the sdl patch as well.

The reason I ask is I'm implementing code in portmaster that emulates touchscreen operations, aka an absolute mouse, and it's not rotated on U8 and Odroid Go Ultra but regular mouse input (like if you connect a usb mouse) is and I'm wondering how the rotation is done in the first place.

or was it done in a udev hwdb transformation matrix

Updates on the buttons for the U8, after some playtime (not even that much, I have yet to charge it, it arrived here at 73% and is still at around 50 and I've played with it for at least a couple hours now I wanna say) and the buttons feel a LOT better. The main issue I am noticing is missed inputs now, and I feel like it might be a software issue just because it's much MUCH worse on drastic (nsmb) than it is on snes9x (smw) for example, I could be wrong though. Any ideas on how to fix this? Or should I just do a membrane swap with one of my handhelds that are coming in?

#

I don't even know if a K36 or R36 Pro membrane will fit in the U8 but I don't know if anyone else has done it, as the r36s is the most popular for membrane swaps and I don't have one

# hearty iron Updates on the buttons for the U8, after some playtime (not even that much, I ha...

My guess is that it has something to do with how it manages the electrical signals. All this is just a guess, but for some reason the electric signal is sometimes weak and it doesnt get recognized by the receptor under the button. That is why a user who added aluminium foil under them solved thr issue, because he increased the conductitity so the signal would get recognized even if weak. I will try adding conductibe adhesives soon, to see if it fixes it. But I have detected this issue in the k36, rx6h and U8, with emuelec and arkos. Therefore I am not sure if it really is the components that lack sensitivity or something in the dtb/kenerl/whatever that causes the electrical signal to drop in power. But it is just a guess

I do think that could deffo be a possible issue tho, it would make sense, although I wonder why it depends on system to system, as it's been SO much worse on drastic than on snes9x for example

and even more evidence towards your idea is that it has repeating signals from my experience too, particularly on the dpad

#

definitely keep me up to date about this if you can and dm me if you have any more info, as if it's not too hard to do, I might do a fix of some sort with my own u8 since I think the buttons are the only thing holding this back from being a budget mini tsp

These were my findings weeks ago. Worst out of the box experience I've had in a long time... Litteraly unplaybale. Seems like a quickly and shoddily slapped together handheld IMHO. I ended up returning both units. Happy I did! Could not bring it upon myself to sell this piece of e-waste to some unknowing poor soul. Any SF2000 or GB300 will run laps around the U8 in terms of usability and playability.

carmine sierra
#

Just to be clear.. I wouldn't call any handheld e-waste just like that!
But in this case, well. Most non-technically inclined people will simply toss this thing after finding out their favorite game is unplayable. At least the RX6H/K36S/M17 and the likes can be played out of the box with much less issues. The U8 on the other hand is an actual case of e-waste..

hearty iron
#

I am one to try and redeem handhelds, I do agree it's pretty bad out of the box, but I'd argue something like an m17 with it's really bad stock fw is worse, plus it's significantly less powerful than the u8 too

#

but you're right, the games are playable, just very stretched and n64 is shoddy

#

meanwhile mario 64 was honestly super good on the u8

#

idk why

#

ima do the hard mods at some point and post my findings

carmine sierra
# hearty iron I am one to try and redeem handhelds, I do agree it's pretty bad out of the box,...

I am speaking purely from a usability perspective. Most people purchasing these handhelds are "average joe's" at the end of the day. Not everyone is an enthusiast and feels a need to redeem handhelds. Most people just want to buy something and just use and enjoy it without the need for tinkering. Those people will end up tossing this thing. I would argue this makes it a failed product.

There is no need to argue the M17's power or FW, since the M17 can be played out of the box without any missing inputs. This makes the M17 an infinite better product off the shelf, even with all it's flaws! Yes the U8 has a lot of potential, but since it's most basic hardware functionality (button inputs) is severely flawed.. It's useless to most people as is. Even if they somehow hypothetically cramped a T820 with an HD+ AMOLED screen under the hood... It wouldn't matter, since I can't properly play a game due to something as simple as the buttons!

hearty iron
#

Eh, agree to disagree

#

Plus I'm more worried about getting the most out of this thing that I can

#

and I have like no experience with hardmodding so I am super worried about it not working and/or damaging the console but I think I'd take that risk if it significantly improves usability

mannn why all these prices show up after I already bought mine 😭

hearty iron
#

maybe I'll get lucky and the controls will fix themselves (every time I have played so far, it's been a better experience than the last)

#

bc the controls aren't all that stiff anymore, just inputs get missed

#

esp in heavier emulators like drastic

#

so hopefully the ink will help, in the meantime I might try the aluminum foil strategy if I can find some thin double sided tape

#

I just am afraid using the tape won't be good for strengthening the electrical signal and that it'll negate the effectiveness of the foil

Just got in my U8. I feel like the travel on the buttons is too much, and it often doesn’t actuate the button. Especially on the far right face button ‘a’.

# hearty iron what is the difference between the two?

Phillips heads are designed to strip before they snap the screw. Pozidrive heads will not cam out and are superior when driven into soft material. There's a rough classification that USA prefers phillips and EU prefers pozidrive, but it's not universal.

but I imagine that if it got stripped that bad, those screws are just made of paper

why must random companies ruin their otherwise good handhelds 😭

quick ravine
#

Yeah, but I guess at the end it is a double edge sword. Since all these emuelec 4.7 consoles are clones of clones it means some of the original errors are carried over again and again. The "good" thing though, is that since there are more consoles with the same issue, the matter gets more attention, and if a solution is found, it can apply to previous clones. If the k36 was the only one with the issue, it probably would have never gotten the attention it seems to have now. I have been looking for a solution for the k36 misdetections since september xD. And many people still dont even notice the issue... usually most reviews dont even mention it, and it should be a primary focus with any EE 4.7 clone.

hearty iron
#

but I've experience it firsthand

#

it's not often enough to be confident in is the reason I think ppl dont notice. Like it happens rather occasional with the ee4.7 devices. I only noticed it on the U8 bc it was rather common

carmine sierra
# hearty iron why must random companies ruin their otherwise good handhelds 😭

Because random companies make random decisions based on costs alone. Leading to random outcomes (and sometimes failed products). There is no real thinking/development process involved with most of these new companies. That's what's happening in the rk3266/rk3128 handheld sphere now. They have run out of RG35XX/R36S/M17 templates and clone ideas so they're just releasing whatever (cheaper) iteration/modification of the same console they can think up at this point. That's how we get all these recent "U8's/RX6H's/R36MAX's/R36PRO's/K36S's/XF43's/G28's" and their likes. It's like throwing old things at the wall under a different angle, and seeing what sticks this time.. Sometimes it works out, most times it won't. The ONLY noteworthy recently released rk3266 handheld I can think of would be: BatleXP G350. Here a company did invest in some development and ACTUALLY IMPROVED upon the original concept for once. Justifying it's slightly higher price in that way. Most other new rk3266/rk3128 handhelds are just "We got RG35XX/R36S/M17 at home" at this point. None of them is as good as the original, yet most of them are priced roughly the same. 😦

# carmine sierra Because random companies make random decisions based on costs alone. Leading to ...

Unfortunately it seems like it, you're right on the money but I just wish they'd put in a smidgen of effort, hell even if the put the effort they put into the packaging into the handheld I'd be fine. The U8 has the best firmware of any 3326 device I've owned (besides maybe the v90 which came with arkos out of the box) and is all around really good software wise. I just hope that through the ppl in this server we can figure out a way to salvage it

#

I have hope that it can be potentially good

quick ravine
# carmine sierra Because random companies make random decisions based on costs alone. Leading to ...

Agree and disagree. Yeah, most of the decisions are based on cost alone, but most of them try some kind on wanky thing to make it differet. The k36 had a gripable ass, the u8 has a wide screen, the rx6h has very comfortable grips and weird lights, the r36 max is a vertical rk3326 with a 1:1 screen, the r36 mini has a central single stick and the g28 is the better version of the m17. Want it or not, these clones bring some innovation and variety. If it werent because all of the mentioned ones have button misdetections, they would be very recomendable for their price.
The g350 is just one more of them that uses a moded emuelec than doesnt have the misdetection issues, and the only "new thing" is rumble. And you wont find many XX series handhelds below 40 bucks.
My point is that there is a market for these clones, and 3 years from now the rk3326 will still rock, becsuse it can play up to ps1 flawlessly. Back in 2017, when I got a raspberry pi and installed RetroPie, it became a dream of mine to someday have a handhelds that could run Retropie. And now every month we get new models of handhelds that are protable retropies for less than 40 bucks.
I just wish they fixed the button misdetection issue.

Ok, so for anyone who wants to try at their own risk, I found a membrain that kind of does the job. I had it in a box, so I could be mistaken about it's origin, but it was all balck and cutted manually by me with a t-shape, so I am almost sure it belonged to a gb300, which is actually very cheap. I only tried it for the letter buttons, and although they arent perfect, I preffer it much more than the OG. That said, since the buttons are connected, when you press Y to run in SMW and at the same time you press B to jump, B feels a bit to soft. However, I still think I fixes misinputs caused by hardware (the usual EE buton misdetectiions are still there). Before the change, the B button was the one with most failed recongnitions, but since the change I have noticed B failing just as much as with Y. Now that I have "fixed" misdetections because of the bad membrains, I plan to download the latest arkos u8 version and try the dtb aeolusux moded. I probably wont have time until the weekend, but I will let you whataver the results are.

hearty iron
#

that's great news potentially, I am willing to give it a try

quick ravine
#

I cant show you because it's inside. But what I mean is that the gb300 has a large one piece membraine, so a few months ago I had tu cut it to try to fit it in a different console. I had cut it with the shape of the depad, so it would fit into place. I will show you a pic of a diferrnt mrmbraine that I had cut the same way

#

I think that is for an snes controller.

#

You probably dont need to cut it so thin. Just make sure there arent any borders that cause it to not fit correctly.

#

It is still not perfect, but I like it much more than the OG feelings. I'm also thinking about cutting the connected buttons, but I will wait until I have done some more testing.

#

You can probably also susbstitute the dpad. The constrast between the hard dpad and new soft buttons can be very noticeable.

Yeah you could always snip the little tabs or connectors. Also maybe filling the + void on the back of the button with glue will depress the membrane more.

#

I'm using a solid 3d printed dpad and it works much better.

I am less worried about breaking my gb300 for that reason than my u8, but also breaking the u8 wont be the worst in the world

# hoary cedar im interested on the inputs of those that changed their membranes I'm running mi...

Hey. So I swapped the letter button membrain with the membraine from the gb300 (re-cutted) and the buttons are much more responsive. I then treid the dtb that you uplaoded with the moded poll rate and debounce, and after playing for 30 minutes it seems to have improved the misdetections, but I still get some misinputs (though I would say with less frequency). I might also end up swaping the dpad membraine as well cause I still think some of the misdetections are caused by the membraine. The issue is still there however becasue on 3 occasions I would be holding B but mario would not run). (3 times in 30 minutes is much better than what I had before). I will do more testing on the weekend. Also, is there any other input sensititvy parameter in the dtb that is far of from what is set for the r36s?

Do you have a k36? those have way better buttons than these so I might make a modified dtb for that to confirm

Hi everyone, yesterday for the first time a strange thing happened. While I was playing it turned off by itself, I turn it back on, play and again like this. The u8 turns on, you can play, after a certain amount of time it turns off by itself. I have 2 and on the other one I tried to insert the same memory card and I played smoothly longer than the time I expected for the crash. Do you know what's happening or if you have any suggestions on what to do in this case?

# hearty iron how have the buttons been for you?

Only the buttons have been an issue but I’m just living with it. I think for $20 it’s a beast. The buttons are weird and I get missed inputs on A and on B some times but I think it’s getting better with use. They’re stiff and just need some wearing to be more usable. I don’t have the time to replace them or open this up.

@hoary cedar hey so since the g350 runs EE 4.7 and it doesnt have input misdetecrions I though we could take some advantage of that. I somehow managed to extract the joypad info from the battlexp dtb and there is no debounce setting. Also the poll interval is 10ms. Would it make sense then to reduce the debounce and poll to 10ms?? (I am basically following AI instructions xD)

#

(Here are both to compare) (k36 vs g350)

hoary cedar
#

Well I guess but isn’t that this already? #1342220912057127066 message

quick ravine
#

Yeah but not the debounce. You lowered to 50ms, and since the option isnt present in the g350 i though it might make sense to reduce it to 10ms. Just exploring

hoary cedar
#

Hang on I’ll make one for k36 i forgot to do so

#

Can you also try to make a version with the debounce at 10ms?

I tried myself, but i got some errors while converting, so I prefer to try a "good" version.

if anything, to my experience, the buttons are less stiff on an r36 pro (although not stiff really on the k36 either, just moreso)

I shared the zed_joystic driver with AI and this is whay it had to say:

"There's a timer used to enable GPIO interrupts with a hardcoded delay of 100ms , and the workqueue delay is also set to 10ms.

The 100ms timer delay in zed_joystick.c before enabling the GPIO interrupts is particularly concerning. It introduces a significant latency before button presses are even detected.

The 10ms workqueue delay might also contribute to missed presses, especially if the system is under heavy load."

hearty iron
#

hmmm I wonder how that would be fixed

#

although that would explain why I feel like there's an input delay in games

#

I was play nsmb on my r36 pro (using it as an example instead of my u8 bc it uses almost the same firmware and has less hardware button issues) and then swapped to my gb300 (playing super mario world) and I noticed how the presses on my gb300 felt instantaneous whilst the r36p felt slightly delayed

#

ideally I'd like to continue to use the stock fw as it's REALLY nice and fits what I need perfectly and then some in terms of settings, but I deffo am struggling with button presses

#

I also have noticed a significant amount of ghost presses on the dpad for said device, it's REALLY bad for a platforming game like mario lol, I'll let go of the dpad but it'll continue moving until I press the direction again, and then it'll stop, it's like joystick drift but on a dpad lol

balmy wind
hearty iron
#

it's so crazy, my Wii U gamepad has drift on it's left stick and it feels the exact same as this except this is much more often, I am unsure what the cause is but I am gonna point at the driver since to my knowledge, the membranes on this clone are quite good

#

dpad drift is never something I thought I'd experience but here we are lol, I hope it's able to be fixed since a lot of devs are working on rebuilding the kernel and I imagine that will include the drivers too

Thanks brother

Ok, so going back to the button misdetections issues, here is the x55's (rk3566 - emuelec 4.5) and u8's (rk3326 - emuelec 4.7) DTBs converted to .txt so you can compare them. I am also reuploading the zed_joystick driver for the u8 that aeolusUX got and the zed_joystick driver for the x55 from the github link that Duri found. The x55 doesnt have ocasional input misdetection issues, so maybe by comparing the DTBs and the drivers we can find a key differences that points to the cause of the ocasional misdetections. (I've tried running them through AI, but the content of the files is to large for them to evaluate correctly. All I got is that they might be using different drive force for the buttons (4mA or 6mA o 8mA), but I still dont really understand how dtb files work and can't verify it, so not sure about that)

final saffron
#

Ok, just some stream of consciousness stuff as I compare the drivers...
First thing is that the x55 analog sticks use a circular deadzone while the u8 is just a square

#

Another thing, u8 driver disables interrupts for a moment, which could definitely contribute to missed inputs. x55 doesn't do this:
disable_irq_nosync(map[i].irq);//防止在probe相关数据结构没有初始化完成中断就进中断服务程序

#

reenabled here after 10ms

timer_setup(&zed_joystick_timer, enable_key_irq_timer_function, 0);
mod_timer(&zed_joystick_timer, jiffies + msecs_to_jiffies(10));
#

It's possible if you hit an ABXY button at the same time as a dpad these disabled interrupts, even if only for 10ms, would miss the dpad/button input

#

The u8 driver has some extra stuff to interpret analog stick as dpad which adds some obfuscation

#

Ok, so pumping the chinese comment through a translator it says:
// Prevent interrupts from entering the interrupt service routine before the probe-related data structures are completely initialized.

#

Oh wait, this is just during init

quick ravine
#

Have you been able to verify if both drivers have the 10ms hardcoded debounce. The AI said both have it, but human confirmation would be better.

final saffron
#
                debounce-interval = <0x64>;
#

0x64 hex is 100 decimal.

#
                if (jk->debounce_interval) 
                        ret = gpiod_set_debounce(map[i].gpiod,jk->debounce_interval * 1000);
#

then the code multiplies it by 1000 to get 100,000 microseconds or 100 milliseconds

#

hey, can you check something on your systems... can you run this from a shell, I'm wondering if it's set:

cat /sys/devices/platform/play_joystick/axis_to_dpad
#

If this is 1 then it might be the reason for weird dpad locking issues. IE if you bump the analog while using the dpad weird shit can happen.

#

This driver sucks though... they're multiplexing one analog input for all the analog sticks by rapidly switching between them, so you only measure a quarter of the axes each time. (right-vertical, right-horizontal, left-vertical, left-horizontal)

Funny story. One time back in the day I got a bug report from Sony testing that the Playstation 2 game I was working on would lock if you hit a button twice in one frame.

#

The game ran at 60 frames per second.

#

I wrote back that that's physically impossible, so they sent over their tester to show me. He proceeded to hit the buttons so freaking fast I couldn't believe it. Locked the game.

Dunno. I don't see anything so egregious that it would crash the system, but the way they do analog-as-dpad in the driver I definitely can see how the dpad could get stuck buttons.

I played a bit of streets of rage 2 on the rx6h using the analog stick and I switched to the dpad for the forward atack, and although I changed from analog to dpad often I didnt seem to notice any misbehaviour outside from the painful ocasional misdetections on the non analog buttons.

Could we increase the drive force of the abxy in the dtb if the issue is weak hardware?

# quick ravine I tried comparing with the x55, but couldnt really map the settings used in th...

There's basically two settings for abxy detection and both are kinda like debounces. First is the actual gpiod_set_debounce which runs in the kernel and maybe the hardware and debounces inputs. I dunno how it works really. It's configurable in the dtb and set to 100ms

Next is the call to mod_delayed_work in the driver code. Interestingly this has a commented out entry that might enlighten what's going on here:

    //是否不需要使用延时 中断内不能有睡眠API
    //mod_delayed_work(system_wq,&map->work, msecs_to_jiffies(zed_joystick->debounce_interval));
    mod_delayed_work(system_wq,&map->work, msecs_to_jiffies(10));    

This basically says whenever we get an interrupt on a button press, wait 10ms and then call the work function which is mapped to gpio_keys_gpio_work_func which looks pretty uninteresting. I'm not totally sure why mod_delayed_work is needed but I think it has something to do with making sure the electrical signals of the button press stabilize before actually reading the gpio registers. So maybe making that 10 to a bigger number will add a bit of input latency but will cure missed inputs. I dunno.

#

Oh, but that might be why your AI thinks the debounce was set to 10ms

#

mod_delayed_work is a kind of debounce

#

Oh, ok reading the docs, gpiod_set_debounce (which uses the debounce in the dtb) is a hardware solution so it might not even do anything. mod_delayed_work is a way of doing debouncing in software.

#

Doing kernel driver development for these gpio buttons when we don't have the hardware engineers to ask questions sucks though

quick ravine
final saffron
#

If you had a hardware logic analyzer you could at least see what the signal bounce looked like on button press and time the debounce accordingly, but I'm not a hardware guy I've only written drivers based on what the hw designer told me

final saffron
#

Hardware eng chatgpt says maybe 20ms

#

Although I have witnessed somebody do a 20ms button press... I couldnt do one. Thats still 50 buttons per second.

#

Does anyone have a kernel dev setup to compile these drivers?

final saffron
#

Anyways, TLDR, I recommend two changes:

  1. Make the mod_delayed_work delay to 20 (from 10)
  2. Make sure /sys/devices/platform/play_joystick/axis_to_dpad is 0

Combine with analog-as-dpad in the driver and it seems likely that stuck dpad buttons are a result.

But you can disable analog-as-dpad in the proc filesystem.

I could probably ask them to build one but not sure if they’d be able to.

but not just on the u8, on the r36 pro as well, do you know where I could find the dtb file? as I can send that one here too if you'd like since it has similar misdetections just less frequent

although it's worse on the u8 I think, could also just be that I have to press it harder as all of the buttons on the u8 are on the stiffer side

if it would help, I can also send a dtb from my powkiddy v10 if it has one as it's another 3326 device that I own

Hey all. New here but just to chime in regarding button inputs on the U8, this is one I've been tinkering with a lot and what made the biggest impact was cutting the tethers between the face buttons. The loop on the tethers on this system are too tight to the point that they damage functionality. I found when I was pressing the A button, the left side of the button compressed far more than the right side, resulting in a lot of missed input. These feel absolutely fine now after doing away with the tethers.

#

yxab feels nice and clicky, yes

hoary cedar
#

first batch is hard to press

#

the body is much better than my myioo a30

#

now i just have to figure out how to install the portmaster thingy WarioThumbsUp

#

The question is, are the analog sticks still wired to multiplex over two wires or did they break it out to be independent signals?

carmine belfry
#

i have no idea how to check that 😨

#

I think I have a photo of the motherboard somewhere and we may be able to see the traces. Probably not though. We only know because somebody, probably aeolus, got the driver code. Still would be interesting to see a pic of the board.

#

This seems to be the only pic I have

i'm a bit scared to open it up as i'm really clumsy and afraid that i'll break something 😅 but i think the sticks have the two-wires thingy

# final saffron You have the new one?

Think mine is the older model. The one with the terrible face buttons that need to have the tethers cut to actually press properly (hence why I opened it)

I spent most of the time trying to fish tiny screws out of the shell 😅

#

Is there an AliExpress store that's definitely selling the newer model? I'd be willing to buy one and record myself opening it up, for science.

I hated the device until I put custom firmware on it and cut those damn horrible button tethers. Now I actually really enjoy using it

The U8 uses one signal for all 4 dpad axes (L-vertical, L-horizontal, R-vertical, R-horizontal) so it gets confused if you're using both sticks at the same time. it also tries to map sticks to dpad entries at the driver level which is wonky. In comparison, the r36s has indipendent traces on the board for each axis so it can read them all at the same time.

anybody knows how to change stickers controls on render96ex/mario64? i've tried messing around with the config file on wordpad but it still uses the default mapping/binding

UnofficialOS support incoming🙂

@hoary cedar hey u have any stability issues with the u8.. I'm wondering if I need to tune the regulators more to that device in the dts I'm using
It is fine as far as es, but once u play a game for 10 mins or so, it just shuts down.. I'm wondering if I need to adjust voltage more maybe?? What's your thoughts

Someone tried to use USB C headphones on the U8?, i dont know how to make It work

#

@hoary cedar ArkOS4Clone have support for U8?

hoary cedar
#

You might need to ask @stray cypress for that I don't have one anymore

#

Should be possible #1274131112351764532 message

The U8 is one of my mainly used systems, so if anyone wants me to test builds on it then more than happy to. As a side note, the Diium D28S (which I also have) can run the U8 build of ArkOS when swapping out the DTB, think it uses the same screen rotation or something but may be easy to add support for that too.

I bought one also cuz i like it.. the 5:3 screen is a nice touch

# jagged haven I shall give this a try

The only other quirk is the led doesn't work unless charging.. all the clones are like this right now because of the way the dtb is.. the units all handle the leds different

#

I just added 3 new xtreme cores to 3326 and 3566 also, fixes n64 performance issues and adds some performance to dc as well.. will be out with the next release soon

Good news for clone users on UnofficialOS, next update, the boot.ini will only need an edit one time when the sd is flashed. Then the user flips the switch on first boot, and can update ota like usual.. if the clone had audio issues (r36s clone/r36 ultra/s600/batman units), no problem, flip the other switch, and the v2 dtb gets set automatically, and will also persist thru ota updates🙂 👍

stone idol
#

No, right under system settings in es..

hoary cedar
#

I think that's better hidden or you'll see people start "accidentally" toggling it. Or is it possible to add a warning?

stone idol
#

It has a warning

#

And then it had to reboot to set the right dtb
