  • @dennis-ctp Haven't found the fix for the Mini Dock's issues with the Omega2s, I'm convinced this is a hardware problem - somehow the Omega2 are different enough from the original Omega that the Mini Dock doesn't work for RX0 serial connection. If you have toasted your wifi connection, but have a 3.3V TTL UART cable and a 3.3V 500mA power supply then the Omegas are easy to hard wire for a serial connection - with just the 3.3V, grounds, Rx and Tx wires.



  • actually the serial connection works for the mini dock, that's how i can get the boot info and sees that it doesn't recognize that the reset button had been pressed



  • @dennis-ctp Ahh, yes but can you do anything? With my Mini Docks I can receive data from the Omega2 but I can't SEND any keyboard commands to the Omega2, ie no command line, can't open Busybox etc, so effectively can't DO anything. The RX0 on the Mini Dock just isn't working with theOmega2 to transmit data to it. These same Omega2s have bi-directional serial communication in a Extension Dock or via the TTL UART described in my last post.



  • mine is bricked, so ofcos the command line haven't show.
    its due to the device operating system is not boot up.
    which is why i need a way to press the reset button so that i can flash it using usb.



  • @Ken-Conrad
    i think i might be facing similar problem like u mention about the minidock

    i manage to get the reset working by connecting the vin to fw_rst (gpio38)
    but it seems that the firmware doesn't wait for me to input any choices and skipped directly to reset

    i'm getting the following:

    You have 40 seconds left to select a menu option...

    Please select option:
    [ Enter ]: Boot Omega2.
    [ 0 ]: Start Web recovery mode.
    [ 1 ]: Start command line mode.
    [ 2 ]: Flash firmware from USB storage.

    Option [
    Boot Linux from Flash.

  • Hi. Im kind of new with the Omega. I ran the firmware update, it bricked and I tried to do what you said without success. I've noticed that my problem is with the kernel.
    All tha i can see is:
    verifying checksum ok
    a lot of text like:

    and then nothing.
    Should I open a new thread or this is ok?



  • well since this particular thread is marked resolved and if you do not think what is discussed in this thread helps fix your issue i would suggest a new thread. your issue is similar to others and i think it works out to establishing a serial connection, transferring the .bin file or maybe flashing i don't remember the details but you can ask and hope for best.



  • This guide MUST be included in the Omega2 documentation



  • You shouldn't need to do anything with a .bin file to fix a jffs2 error, unless you've flashed a .bin file for the wrong board (2 vs 2+, or worse original Omega), or you used one of the bad .bin files that were published months ago (and hopefully withdrawn??)



  • I connect FTDI232 to UART0 (RX0 (gpio13) to FTDI_TX, TX0 (gpio12) to FTDI_RX).
    Press f and enter to enter in failsafe mode.
    Type firstboot -y.
    Wait about 20 min.
    And Omega2s+ unbricks



  • @Alexandr-Didenko We can reflash (flash the same or a newer or an older or a custom - working or not working - firmware into) Omega2(+) from a USB memory device with @Colt-Burns's procedure.

    firstboot on the Serial Console is "only" a Factory Reset / Factory Restore of the installed firmware.
    It's same as type firstboot on CLI (either failsafe or normal mode) or a long press of the RESET BUTTON (FW_RST).
    So - I think - your Omega2S+ was not "bricked".
    Did you really have to wait 20 (twenty) minutes after typing the firstboot command? It looks fairly strange.
