Qmk_firmware: Failed to upload Redox Firmware from Linux

[MarkuBu]

Hi,
I want to upload a firmware from Linux to the Redox Keyboard, but the upload failed and now the keyboard is dead.

I had to run make ::flash with sudo to make the serial port available, but I just got error messages like this

avrdude: Error: butterfly programmer uses avr_write_page() but does not
provide a cmd() method.
 *** page 11 (addresses 0x590c - 0x598b) failed to write

avrdude: reading on-chip flash data:

avrdude: error: programmer did not respond to command: set addr

I also tried arduino and dfu instead of flash, but dfu doesn't work (as expected) and arduino was the same result as flash.

What's wrong? I hope someone can help me because I don't want to dump 200€ just because of a software issue

Regards
Markus

You can try sudo systemctl disable --now ModemManager.service or the caterina rules at https://docs.qmk.fm/#/faq_build?id=linux-udev-rules.

@zvecr, you're a life saver! I happened to run into the exact same problem just now on the redox_w, and disabling ModemManager worked.

@zvecr disable tha ModemManager helps for me too. Big big thanks from me. Now I can start modifying the default layout
