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

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?

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

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
