I'm working on a ESP32 Flasher so you can flash the WiFi Dev Board from the Flipper by itself. Help would be great if anyone would like to.

Good luck rewriting esptool

This sounds cool

I think I read some where that it already has the ability to do that. But no interface or boot script to start up the hw device. It would be nice to have a device with preloads of various Devices you need to flash. Like my son-off switches smart home outlets.

Tomorrow I'm free so I can start development again if you'd like me to.

Oh no. You didn't get to push anything to github?

Is it using the library that I linked?

Ive succesfully implemented a host system that implements the ESP32's ability to do a "OTA" update over Serial (see espressif docs) i have my own source for this, if you would like help with your implementation please reach out

Oh this is awesome, I had this idea as well.

#

Since the flipper is flashed from serial it should be possible over esp

Yeah I'm sorry I would love to help but I don't know c++

#

I can do some syntax fixes but that's about it

#

Just simple debugging

#

Isn't that what this is

#

Oh

#

No it's the other way around

#

Sorry I nisread

It's alright. It would be a cool idea though.

It's mostly UI at this point. You can see how I integrated the lib in my latest commit. Go ahead and check it out, feel free to pull it off into its own app (as long as I get some credit 🙂 ).

I'll make it into its own app, and I will make sure to give you some credit dw. I don't use the marauder board that often, but I've been porting CircuitPython to it. I can't make it official yet because I need a custom USB PID and VID, and I'm not exactly in the position to that. Since it does use an ESP32-S2, it's possible that Espressif can give me a custom PID under Espressif's VID. I have yet to do that.

#

Either way, this means I no longer need my PC to flash the board.

oh

#

is it possible to not flash a bootloader with the app?

#

and just flash the fw

trim pivot
#

I'm planning to allow that, but right now it's expecting all the files

#

It looks like S3 also needs a boot_app0.bin at 0xE000

wise rapids
#

all esp32s have that

trim pivot
# wise rapids all esp32s have that

I don't think boot_app0 is needed because it's supposed to be a switch for which fw to load, and there's only one.

I'm still going to add it as an option to avoid confusion.

I am now working on making the ESP flasher into its own standalone app (instead of inside the marauder app). I didn't realize it would already be this useful.

I just remembered about this

#

I've been so busy with running Linux on the ESP32-S3 that this completely slipped my mind

?

#

the bootloader and partitions from github and then firmware compiled by me (works normally)

trim pivot
#

What about boot_app0? I don't know what else would be different - I thought it was just a different bootloader address.

#

Just went from evil_portal to marauder, no boot_app0 used, worked fine, flashed back to evil_portal with no boot_app0 and it worked perfectly as well

#

my only suggestion, if you're taking them, would be to allow to use a custom "playlist" of files to make it easy to swap between them

#

thanks for the great work

Ok i test, i have few esp32 boards but my flipper not detect board.

wise rapids
#

How do you know your flipper doesn’t “detect” it?

When i go to wifi options and test them all, i get black screen or wait, sry my bad english, i have to check it from flip
