Today after rebooting my Edison, I can't access the Wi-Fi and Bluetooth interfaces anymore, and my attempts to reinstall the firmware also fail. Earlier today I have tried to make an external Bluetooth dongle work on my Edison over the OTG port using a custom-compiled btusb kernel module. Possibly something broke during that attempt, hopefully only software-wise.
How can I get my Edison board back to factory settings, or proceed in finding out what's wrong?
I just noticed that /dev/root (mounted on /) was 100% full, with no blocks available. This may have caused some problems. I removed some files from /opt and now only 68% is used. Still the issues from my first post persist. Any ideas?
