One moment, I was flashing the firmware without problems. Five minutes later after I made another change to the layout, the command “make flash” started hanging at the prompt “Press ENTER when ready…”
I tried a saved *.ino file, and had the same problem. I deleted and reinstalled Arduino and Keyboardio support, and the problem persisted. Does anyone have any idea how I can recover and continue flashing? Is there a reset button on the hardware?I suspect there’s something very simple involved, but I have no idea what.
