Upgrade Error



  • Today (20 July) I logged onto my omega via WiFi and did an oupgrade -force command.
    After a very slow download it eventually came back to say it had upgraded me to the new version. The last line was something like "Could not delete files" that I have never noticed before.

    Now when I power up the omega the light blinks once, followed by a solid light for 5 seconds then it goes out.
    I am connected via PC and it can see Silicon Labs CP210x USB to UART bridge (COM4) connecting to this with PuTTY gives me no results?

    Any ideas what to do next, I have tried holding down the reset button for 11 seconds with no effect.

    @Lorcan-Adrain Hmmm... super odd...
    Nothing comes up on Putty even if you try pressing reset? At the very least, you should see some boot sequence messages.



  • @Lazar-Demin 0_1469045006430_2016-07-20.png
    All I get is a green cursor.
    Pressing any key on the keyboard does nothing,
    I have tried setting COM4 to both 9600 and 115200 BPS.
    At this point the light on the board is off.



  • The other thing I have done is:-

    Press and hold the reset button.
    Attach power to usb.
    The light blinks.
    After 10 seconds the light goes solid.
    release the rest button
    The light is now solid.

    I have also run both PuTTY and MobaXterm on COM4 after the above, but still cannot get it to communicate.

    @Lorcan-Adrain Can you try connecting to the Omega via SSH?
    It's definitely possible that the Omega is working fine but the serial terminal is not available for some reason, especially since the LED is indicating that the Omega is booting correctly.

    If you can, try using a different Dock as well.



  • I cannot connect vis SSH and also cannot connect with http://omega-0b85.local/
    Both did work fine before I did the oupgrade
    Only have the mini dock.



  • I had several problems till i could make a serial connection. I just also use two mini docks. But after a while i found out, to play around with USB Cables (miniusb), that it worked. So try a other USB cable ... if you have a new tablet just try this cable.

    Did you activate the putty windows with the mouse and hit enter?

    For me it looks like that your memory is full because of a incomplete update.

    So for me, first step > resolve serial connection problem.
    Second step > manually factory reset your omega. Lazar already described this procedure in wiki/forum.



  • Thanks for the advice, I did spend a few hours trying lots of things. I did get something to work and it looked like i had access to uboot, tried again without any luck. I used screen /dev/ttyUSB0 115200 in PuTTY .
    If I do a factory reset I get these two lines in PuTTY. I cannot enter via keyboard/mouse.

    Button was pressed for 10 sec...
    Starting U-Boot netconsole...

    It freezes at this point.

    This is in PuTTY when I do a normal power up. Not sure what what it is doing.
    Will try again tomorrow from a different PC and a different USB cable.

    As i mentioned ... full memory and not able to release space. Let me see if i find the Tutorial how to manually factory reset ... voila:

    https://wiki.onion.io/Tutorials/Updating-the-Omega#getting-back-to-a-factory-image-omega

    you can try to take the newest image directly > omega-v0.1.4-b330.bin



  • @Luciano-S. Thanks for the link. Unfortunately I cannot get the unit to boot like it did in the past, only get it into u-boot mode.



  • it looks like tat you just can debrick with a network module ...
