Just today, I received and made a Corne kit with nice!nanos. However, I can’t seem to get it actually working. I’ve built the default ZMK configuration and tried to flash it to the board. It seems to accept the file, exits bootloader mode and disappears from my file manager. But the blue light just blinks, and I can’t type anything with it. I know that isn’t much more to go off of than “it doesn’t work”, but I can’t see anything in the docs or elsewhere, and I’m not sure where to look next.
