With your usb drive with firmware.bin inserted first type:OK, so I screwed up, I edit the config files manually from h t t p s://github.com/ijuintekka/fusee-a5 but wired access no longer works for me. I think the easiest way for me to sort this is just to flash the firmware.bin.
I put it on a usb stick and inserted it into the unit, but I can't see it anywhere what's the easiest way to reflash the firmware?
I've got access via wifi and can ssh from there just fine
ls /dev/sd*
Look for your partition, it will most likely be /dev/sda1 but it could be /dev/sda in some isolated cases.
Next: mount /dev/sda1 /mnt
Where sda1 is your partition containing firmware.bin
Finally: sysupgrade -v /mnt/firmware.bin
To reflash the firmware.
