I am unable to update firmware on a new model 100. I get an “error updating firmware” message in chrysalis and looking at the developer console I see dfu-util exited abnormally with an error code of 74
. I checked the dfu-util source code for exit code 74 and it’s # define EX_IOERR 74 /* input/output error */
so probably some fairly generic error communicating with the keyboard over USB.
I have tried both the instructions in the chrysalis GUI (hold PROG for start of update process) as well as the variation described in this forum post (hold PROG before plugging in USB).
I have tried rebooting and updating my arch packages. This error happens consistently. I am able to change and save my keymap though and the model 100 does work properly as a keyboard both halves.
OS: arch linux (kernel 6.1.1-arch1-1 #1 SMP PREEMPT_DYNAMIC x86_64)
Chrysalis: 0.12.0
Firmware attempting to flash: 0.90.1
