Stuck at "uploading" when flashing new firmware from Fedora Linux

Help and Getting Started
1

Hi I was trying to change the layout, after following the instructions I tried to flash. it got stuck and keyboard wouldn’t turn on at all, ive lost the very first error message now. After reading on the forum I managed to get it into bootloader state by pressing the prog key and plugging in. that didn’t help because Arduino ide couldn’t find the serial port.
so I opened it up and while pressing the reset button ide finally finds the port, and hangs forever at the following message. one more thing the red light shifts from prog key number 1 before freeze.

That looks to me like there’s an error in the code that’s making it crash…can you post the code you’re trying load on it?

3

its all fresh from the repo

My first guess is that this is related to ModemManager attacking the serial port.

Did the instructions you followed talk about udev rules?

Device or resource busy has some more details on what might be up.

Nah. The failure happens while the computer is talking to the bootloader on the keyboard. It’s most likely something else grabbing the serial port.

The log posted by @mygnu shows Found programmer: Id = "CATERIN"; type = S

That means that the serial port communications start out ok and that the keyboard gets into the bootloader ok, but it never gets done uploading.

Thanks

sudo systemctl stop ModemManager.service

fixed the issue, I’m on Fedora 26 if anyone else is stuck.

Oops, my bad. I was thrown off by the red light moving then stopping, as that’s what happened to me :stuck_out_tongue:
