Just assembled, booted a few times, but now doesn't.

I just assembled the kit, and was playing around with it, and managed to get it on the wifi and load some web pages.  I rebooted it a few times and that worked fine.

I tried to make a SD card with the experimental nixos here: https://www.olimex.com/forum/index.php?topic=7186.0 and booted it, but it looks like nothing happened.

When I came back to it a few hours later it was dead, and the power button doesn't turn it on.  (It still doesn't)

The only thing that seems to trigger any activity is plugging in the power supply, which outputs the following over serial and then it dies.

I downloaded the official latest linux image and flashed that to a microSD card and tried to boot from it (by plugging in power), and as far as I can tell that doesn't do anything either.

Any pointers for how to debug or fix would be appreciated.

Which image did you use to prepare the card? Is it the one in this archive:


Can you try using the free version of balenaEtcher to prepare the card?

Is the the same result?

Yes that is the image and yes balena etcher to flash the card.

Also now (somehow) booting from a card works.  I still don't know what's up with the EMMC, and I would be interested in any guidance for how to decode the UBOOT logs.


Few pointers:

Did you run the script to transfer it to the eMMC? Does it report any problems?

Is the eMMC visible and accessible when you boot from the card?
