    Dear all,

    my Udoo Neo does not seem to boot anymore. I did the following trouble shooting:
    1) checked the SHA1 (correct)
    2) I reflashed a SD card
    3) checked the voltage and current of the power supply (in spec)
    4) the green LED lights up, however, no red light flashes up (this used to be the case before)

    Any idea from your side what to try would be highly appreciated.

    Greetings from San Francisco,

    Thorsten

    Dear Udoohorst,
    in order to exclude hardware problems would you mind testing the previous beta and check if that work?

    Sure, will do!
    I already tested the beta (UDOObuntu_neo_v2.0beta5.img) and it didn't work, but please let me try this again with a new SD card. It used to work with the beta version, i just recently wanted to update to the new version to use the 7 display as well.

    best,
    thorsten

    Hi. Do you have a serial-to-usb adapter? On the J7 connector there is the CPU debug port. It would be useful to read the output.

    Hi Francesco, thank you for your reply.
    I don´t have a serial-to-usb adapter. Is there a commercial one that I can buy to read out the output? If not, if you send me the wiring diagram, I could try to make it by my own.

    Best regards,
    Thorsten
