Tried to update the firmware on my Model 01 and have run into a persistent difficulty. When trying to flash the stock firmware (here: https://raw.githubusercontent.com/keyboardio/Model01-Firmware-Builds/master/v1.22-MP2-BUILD/atmega32u4_firmware.hex)
I get persistent hangs. Pastebin error here: https://pastebin.com/DwjZwfPi
Similar difficulties when I try to flash using the Arduino IDE (1.8.7), errors here: https://pastebin.com/2ndYPhVe
In terms of getting the Keyboardio into the bootloader, plugging in with prog held down “works” insofar as the Arduino IDE sees it, then gives the errors. Equally, hitting the reset button on the firmware gets it into the boot loader, but the errors persist.
I’m running Ubuntu 18.10, the keyboard shows up when I run lsusb:
Bus 003 Device 006: ID 1209:2301 InterBiometrics Keyboardio Keyboardio Model 01
and variously connects as either /dev/ttyACM0 or 1 seemingly at random when it plugs in/gets reset. If that’s the issue, I have no idea how to fix it…
Thoughts greatly appreciated, as I’ve thoroughly tapped my (very limited) knowledge of microcontrollers and I’d rather like to get back to using what has otherwise been the best keyboard I’v ever owned.
