giuliomoro I flashed it again there and seems to be working now without the SD. Hopefully will be alright. Thanks again for the quick help!
I'd suggest to keep it like that for a while and see how it goes. If it is a hardware fault, it will come back at some point, so make sure you do keep a copy of your projects off the board in case it fails again!
OK will do. Will let you know if anything happens! Thanks again.
Hi Giulio, I have plugged it in again today and now the pwr light flashes once and that's it, no other lights flash or turn on.
