Einsy bootloader
Hello, I followed the tutorial carefully to flash the bootloader, but I have an error on the "reset" pin, I tried the GPIO 12 and 26, same error.
"Can't export GPIO 26, already exported/busy?: Unknown error 517
avrdude done. Thank you."(when I try to backup the firmware)

I don't see 26 being used for anything in the guide: https://github.com/Prutsium/3D-Druckerplausch-Klipper/wiki/1_Flash_Einsy_USB_bootloader_en

Repo for config file(s) for Prusa MK3(S)(+) with Klipper - Prutsium/3D-Druckerplausch-Klipper
Can you paste the contents of /etc/avrdude.conf ?

yes it was 12, but as it didn't work I tried with another pin by reconfiguring the .conf
Right. What does your avrdude.conf look like now and can you post a pic of the wiring?

it's a CB1 board ... maybe..
yeah things might be different there, reset pin might already be used for something. Two very different platforms.
try some other random GPIO for the reset pin

ok i will try, thx
I've tried many other pin, but the problem is always the same.
Unfortunately i don't own either a Prusa Einsy or a CB1 so i can't be of much help 😦
both are in the experimental stage in RatOS as well
I have plenty of cb1 but no einsy to test flashing

I will buy a PiZero to flash the einsy board, thanks for help.
