    Hi

    I've had a quad from late 2013 which I've tried starting to use again. Around the time I got it I found that everything worked well with the Arduino and Ubuntu images I wrote to the flash card. I didn't use for a period of months and then over Christmas tried using it again with the new Ubuntu image.

    The power supply I've got should deliver 12 volts at the amps required and was working well with the previous SD images.

    I have tried using the Udoo linux distro UDOObuntu for the quad. I get to the splash screen on the monitor and then it appears to boot again. Attaching the serial cable I find it some some sort of reset
    ...
    Reset cause: POR
    ..

    The full output is blow showing the boot sequence. I'm starting to suspect some chip error. Can anyone help?

    Based on the "Reset cause: POR" (meaning Power-On Reset), I would try swapping in another 12V supply if you can, if only to rule that out. Power adapters do occasionally go bad over time, usually from faulty electrolytic capacitors inside, and can then start putting out "dirty" power (full of high-frequency noise) that still measures OK on a simple DC meter.

    That's assuming the POR report is accurate, though. Some ARM boards report this unconditionally regardless of reset cause... now I'm curious to test my Udoo's to see.

    If it's not the PSU, and you have another SD card on hand, try maybe writing the Debian image to it and booting from that.

    Thank you. I will give another power supply a try.
