Gyro works on quicksilver but not betaflight | Betaflight | Page 1

im revisiting an old problem,
i flashed quicksilver on an aio just so see what it was like and when i tried to flash it back to betaflight the gyro wouldn't work. its a bmi 270 and the accelerometer still works in betaflight but not the gyro. if i flash back to quicksilver then gyro works as normal again.

the target for the board is TCMMF411 but its the aio from the tyro 79 pro so its the target from another board. any ideas why quicksilver works and betaflight doesn't?

the original firmware version of the board was 4.3.0 and its back on that now with the dump i took before flashing to qs which i have also included

if anyone has any clue why this is some help would be appreciated

The current Betaflight target for it does not have the BMI270 define

#

gentle flume The current Betaflight target for it does not have the BMI270 define

how would the accelerometer work then?

#

i have also tried on new betaflight with the custom define for the bmi 270

#

same issue

gentle flume Oct 1, 2025, 8:12 PM

#

so on BF 4.5.2, given the target TCMMF411, the accelerometer works, but the gyro does not?

wanton trench Oct 1, 2025, 8:20 PM

#

gentle flume so on BF 4.5.2, given the target `TCMMF411`, the accelerometer works, but the gy...

with the custom define for the bmi 270 yes

#

its the same as 4.3.0

#

but 4.3.0 doesnt need the custom define i dont think

#

the accelerometer still works

gentle flume Oct 1, 2025, 8:20 PM

#

stuff before 4.4 used a different target system

#

@round moss have you ever seen something like this? Accelerometer part of the BMI270 works correctly, but the gyro doesn't in the TCMMF411 target with Betaflight 4.3 and 4.5 with custom defines.

But both work correctly in Quicksilver.

#

maybe some severe resource conflict?

wanton trench with the custom define for the bmi 270 yes

Are you still getting the CALIB error?

round moss Are you still getting the CALIB error?

yeah

#

also idk if it was like this before but the accelerometer loos really noisy, its not like that in quicksilver

gentle flume Oct 1, 2025, 9:06 PM

#

at a scale of 2, anything will look noisy

wanton trench Oct 1, 2025, 9:07 PM

#

it doesn't go any higher than 2 lol

gentle flume Oct 1, 2025, 9:07 PM

#

sorry, looking at the wrong thing

round moss Oct 1, 2025, 9:08 PM

#

And the gyro looks completely dead

#

Can you show clear photos of both sides of the FC?

gentle flume Oct 1, 2025, 9:10 PM

#

it works all good in Quicksilver

wanton trench Oct 1, 2025, 9:11 PM

#

Thats the top

#

I need to take 2 motors off to get to the bottom

round moss Oct 1, 2025, 9:11 PM

#

You are using the tcmmf411 quicksilver target?

wanton trench Oct 1, 2025, 9:11 PM

#

yeah

round moss Oct 1, 2025, 9:14 PM

#

Can you get a clear photo of the gyro?

wanton trench Oct 1, 2025, 9:17 PM

#

#

looks like it says sl 1f6

#

or 5l idk

#

Found a crappy kids microscope

#

I don't think its getting better than that

limber vortex Oct 1, 2025, 9:27 PM

#

May I add my experience? I've had the same issue with the same board, also from the Tyro79 Pro

wanton trench Oct 1, 2025, 9:27 PM

#

limber vortex May I add my experience? I've had the same issue with the same board, also from ...

lol

#

in this case quicksilver might be the fix then

#

if we cant figure somthing else out

limber vortex Oct 1, 2025, 9:28 PM

#

Mine flies with betaflight 4.5.3

#

Try that

#

Its a weird board anyways tho

wanton trench Oct 1, 2025, 9:29 PM

#

just to prove im not crazy here is the gyro working on quicksilver

wanton trench Oct 1, 2025, 9:30 PM

#

limber vortex Mine flies with betaflight 4.5.3

with just the USE_ACCGYRO_BMI270 custom define?

limber vortex Oct 1, 2025, 9:30 PM

#

With nothing

#

Erase full chip and 4.5.3

#

I dont remember selecting anything special

wanton trench Oct 1, 2025, 9:31 PM

#

tcmmf411 as the target aswell?

limber vortex Oct 1, 2025, 9:31 PM

#

Yes

wanton trench Oct 1, 2025, 9:33 PM

#

limber vortex Yes

now i get no gyro detect

#

i dont think its gona work without the custom define

#

sure we have the same board?

limber vortex Oct 1, 2025, 9:34 PM

#

Uh

#

Yeah

#

I tried multiple versions

#

4.5.3 then just worked

wanton trench Oct 1, 2025, 9:35 PM

#

bc there is no way yours works if you have a bmi 270

limber vortex Oct 1, 2025, 9:35 PM

#

Its a tcmmf411

wanton trench Oct 1, 2025, 9:35 PM

#

do you have the tyro 79 with the stack or the tyro 79 pro with the aio?

limber vortex Oct 1, 2025, 9:35 PM

#

Aio

wanton trench Oct 1, 2025, 9:35 PM

#

wth

#

check what gyro you have

limber vortex Oct 1, 2025, 9:36 PM

#

Sorry, where?

wanton trench Oct 1, 2025, 9:41 PM

#

limber vortex

its supposed to have a bmi 270

#

maybe they changed gyro at some point

limber vortex Oct 1, 2025, 9:42 PM

#

¯_(ツ)_/¯

#

How would I check besides that

#

Because im not tearing mine down lol

wanton trench Oct 1, 2025, 9:42 PM

#

if it says that and it works thats the gyro you have

limber vortex Oct 1, 2025, 9:42 PM

#

Alrighty

wanton trench Oct 1, 2025, 9:42 PM

#

wanton trench Found a crappy kids microscope

in oscar liangs post he has the same gyro as me

#

bmi 270

#

does your aio look the same other than the gyro?

#

if you can see

limber vortex Oct 1, 2025, 9:44 PM

#

Looks exactly the same

#

Wait

#

Where is the baro on yours

wanton trench Oct 1, 2025, 9:44 PM

#

its where his is

#

on the right of the mcu

limber vortex Oct 1, 2025, 9:45 PM

#

I think mines close to some pads, i remember managing to get some solder on it

#

Yes I remember right

#

So I got a different one

#

Weird

wanton trench Oct 1, 2025, 9:48 PM

#

when i include the bmi 270 its gets detected

#

bu the gyro trace is dead

#

accelerometer still does stuff

#

at this point i would rather the gyro just be dead

limber vortex Oct 1, 2025, 9:50 PM

#

Lol

wanton trench Oct 1, 2025, 9:50 PM

#

instead of Schrodinger's gyro

limber vortex Oct 1, 2025, 9:50 PM

#

Haha

#

Yeah i messed with mine 3 days long too until it finally wanted to fly

#

But whats also weird

#

I had to set yaw 180⁰ on the gyro

wanton trench Oct 1, 2025, 9:51 PM

#

like its not flying even if i get it working but i want to re use the aio for smth else

#

and i dont realy know what im doing in quicksilver

limber vortex Oct 1, 2025, 9:52 PM

#

Tbh with you I haven't even heard of that

wanton trench Oct 1, 2025, 9:52 PM

#

?

limber vortex Oct 1, 2025, 9:52 PM

#

Quicksilver

#

I couldn't tell you either

wanton trench Oct 1, 2025, 9:52 PM

#

avocado

#

like i got it to fly but i only really know how to tune betaflight

#

and im not exactly the best at that

#

it also has a broken motor and no receiver soooo

#

its not going anywhere

limber vortex Oct 1, 2025, 9:54 PM

#

Another one for parts yaaayyyy

#

I got like 3 broken ones lying around lol

wanton trench Oct 1, 2025, 9:55 PM

#

rate the vtx antenna

limber vortex Oct 1, 2025, 9:55 PM

#

That gonna be a range record trust

wanton trench Oct 1, 2025, 9:56 PM

#

it wasnt even as bad as i thought it would be

#

for being inside the frame

limber vortex Oct 1, 2025, 9:56 PM

#

Dang ok

#

But i doubt its very healthy for the vtx

wanton trench Oct 1, 2025, 9:57 PM

#

#

that was the coolest it ever looked

#

but it flew like crap lmao

limber vortex Oct 1, 2025, 9:58 PM

#

Mine looks like this

#

Nooot for much longer tho

#

The screws at the bottom barely still gripping

wanton trench Oct 1, 2025, 9:58 PM

#

04 lol, talk about polishing a turd

limber vortex Oct 1, 2025, 9:58 PM

#

😂

#

It flies damn good tho lol

wanton trench Oct 1, 2025, 9:59 PM

#

mine flew so bad it instilled fear into me

limber vortex Oct 1, 2025, 9:59 PM

#

Pfff

#

Its the gyro xD

wanton trench Oct 1, 2025, 9:59 PM

#

maybe it was never meant to be

#

when i build a 5" as my 2nd quad i was like wait, this is what a quad is supposed to fly like????

#

it was eye opening

limber vortex Oct 1, 2025, 10:00 PM

#

Lol

#

Thats sad bruh

wanton trench Oct 1, 2025, 10:01 PM

#

it was on betaflight defaults so thats probably part of it

#

i flew it for ages with the number of poles set wrong lol

#

and the bearing sound so bad 💀

limber vortex Oct 1, 2025, 10:01 PM

#

Why that

wanton trench Oct 1, 2025, 10:02 PM

#

why what?

limber vortex Oct 1, 2025, 10:02 PM

#

Whyd it sound so bad

wanton trench Oct 1, 2025, 10:02 PM

#

bc i have smashed it into the ground many times

limber vortex Oct 1, 2025, 10:02 PM

#

Alr fair haha

wanton trench Oct 1, 2025, 10:03 PM

#

this was fun

#

a motor wire fell of mid air

limber vortex Oct 1, 2025, 10:03 PM

#

Bruh

#

I already wondered what happened

wanton trench Oct 1, 2025, 10:03 PM

#

i blame the wires just being the motor windings

limber vortex Oct 1, 2025, 10:04 PM

#

They stay in place nicely tho!!😂

wanton trench Oct 1, 2025, 10:05 PM

#

i just realised the 04 costs more than the whole quad lmao

limber vortex Oct 1, 2025, 10:06 PM

#

...

#

Dont question my choices!!

#

(I know theyre terrible)

#

😁

wanton trench Oct 1, 2025, 10:06 PM

#

hey if you have fun flying it nothing else matters

limber vortex Oct 1, 2025, 10:06 PM

#

I do

#

Especially because its not even my quad haha

wanton trench Oct 1, 2025, 10:07 PM
