you said one of the USER LEDs turns on briefly on boot? Could you make a short video? Also can you try and remove the Bela cape as explained here and see if that allows it to boot?

Same thing happens with the cape removed. Is there somewhere I can send the video? It won't let me attach.

right, it would seem that the eMMC (internal memory) got somehow corrupted. Have you got an SD card (at least 4GB) at hand? You could flash the latest Bela image on it, then remove the Bela cape and try and boot it using the instructions at option 3.

I don't think so, is there any other way? I'll have a look for an SD card.

I'll try give this a go then.

giuliomoro Thank you very much! That seems to have done the trick and the board seems to be working fine now. Should I leave the SD card with the flashed image in the board?

    that's good news!

    OG93 Should I leave the SD card with the flashed image in the board?

    if you do, it will keep booting from it. If you remove it, it will boot from the built-in memory (eMMC)

      giuliomoro The board doesn't work when the SD card is not in it, is that something I should be worried about?

      did you flash the eMMC from the SD card? That'd be this step.

      If you already did that, try again, but yes, we may have a problem. I think I had one BBB (out of a few hundreds I handled myself) where the eMMC was not working as expected: it would seem to be fine if you flashed it, but then on reboot it failed. Maybe this is a similar issue? After all, your initial failure was probably linked to an eMMC corruption ... maybe it has failed completely?

        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.

        I'd like to add to this; today, a project that is a week away from being live, I fried the PB/Bela+MultichannelExp with the same results just now.

        I could cry. Can't seem to buy a new pocketbeagle 1) in time 2) in the modern world
