Fixed it! I reverted to the original atreus tmk library, and that wouldn't load
either. Googling around for error messages turned up some problems with the
Debian modemmanager package. Apparently if that's not configured properly it
will take over the /dev/ttyACM0 port, blocking uploads. Purging that package, I
was able to load the original tmk firmware, and from there I could reload my
qmk modifications as usual. Not sure if there might not have been something
else complicating things, but at least my keyboard is back on line. And I know
how to physically connect the reset next time I brick it.
Best,
Tyler

Following the directions here: https://www.pololu.com/docs/0J61/10.2 I ;
managed to clear the chip, but I still can't load anything new. Even the
default atreus layout in qmk produces a similar list of errors as I
originally reported.

Hi,
After trying unsuccessfully to upload a new firmware, my keyboard is now
completely unresponsive. Here's what I did:
1. Keyboard was working fine, using a modified qmk firmware.
2. I made a few changes and recompiled the firmware
3. I tried to upload it, and got some errors (pasted below)
4. After this, the keyboard is completely unresponsive -
- typing doesn't send anything to the computer.
- Entering dmesg --follow and then plugging it in to the computer,
there's no indication that the keyboard is detected.
- Plugging it in, I can't see any LED lighting up (but I'm not sure
exactly where it should be, even having opened up the case).
I suspect I may have bungled hitting the reset button during the upload
process, if that's possible. I've used the same process without problem
before, although I changed the key that activates the layer the reset
button is on.
How can I reset the firmware? Can I manually trigger the reset somehow?
Thanks,
Tyler
