    b216
    Feb 22, 2018

    • Fix for Omega2 Pro DTS file - OS can now use all 128 MB of RAM

    Let's upgrade to b216 with the usual oupgrade -l -f command on the Serial Console.

  • If you already have an Omega2 Pro please let us know:
    What is the FirmWare and the UBoot version of your Omega2 Pro?
    What is the output of the following commands:

    • cat /proc/mtd
      dd if=/dev/mtd0 of=/tmp/u-boot.bin
      md5sum /tmp/u-boot.bin
      dd if=/dev/mtd1 of=/tmp/u-boot-env.bin
      md5sum /tmp/u-boot-env.bin

    • fdisk -l
      dd if=/dev/mmcblk0boot0 of=/tmp/mmc_boot0.bin
      md5sum /tmp/mmc_boot0.bin
      dd if=/dev/mmcblk0boot1 of=/tmp/mmc_boot1.bin

  • @crispyoz Thank you very much. This post was very kind of you. :-)
    Sorry for being cheeky but the fdisk /dev/mtdblock5, /dev/mtdblock6 and maybe some /dev/mmcblck lines have been left out from your post.
    Could you upload the 'u-boot.bin' and 'u-boot-env.bin' files somewhere?
    What is your Omega2 Pro firmware version please?
    onion os version

    Thank you in advance.



  • Hi @györgy-farkas here are the disk stuff you requested. I'll find the files and put then on OneDrive and post the link.

  • @crispyoz Many, many thanks! :-)



  • My favorite thing about the pro is that it's a 2+ with a power dock so it's slimmer but just a little longer. My second favorite thing is the big juice tri-colour LED.

    My least favorite thing is that I only have one and the others i ordered are nowhere in sight and noone replies to my enquires for the status of my orders that were to ship on 31st March.



  • @crispyoz
    At least you got one. My five refused to be tamed and seem to have escaped into the wild. :( But I'm ever hopeful they'll find their way home one day and hopefully soon. :)



  • @crispyoz A simple fdisk -l command should display all partitions (and exit).
    For example this is its output on my Omega2 "Pro" simple ;)

    I didn't know that those two boot partitions are correct or some error.

  • @György-Farkas said in DIY Omega2 Pro - Try it before buy:

    didn't know that those two boot partitions are correct or some error.

    Sorry @György-Farkas were you asking a quesiton?

    About the last two questions: I didn't know that the second boot partition (/dev/mmcblk0boot1) is correct or some error on my Omega2 "Pro" (Omega2+ and a 16 GB eMCC board with microSD adapter).

  • Hi @crispyoz
    OK, both mmc_boot partitions are totally empty (filled with 0x00).
    So Booting from External Storage is a white lie on Omega2 Pro too.
    Thank you.

  • @György-Farkas I never saw where it said it boots from external storage, I just see the pro as combo of Omega2+, PowerDock, memory expansion and a much better LED. It's also slimmer because you don't have to plug in the Omega since it's soldered in. I just wish they're get rid of the USB-A plug.



  • @crispyoz Please take a look at the official Onion Omega2 Documentation. The Onion guys advertise the pivot-overlay as Booting from External Storage.



  • @György-Farkas I misunderstood what you were saying. I thought you were saying the Pro boots from external storage.I am aware Omega 2 CAN boot from external storage.
