DIY Omega2 Pro - Try it before buy



  • @cas I got in early but I should have ordered more, I only have one :( . It's seriously holding up my project so I like György Farkas idea.

  • @crispyoz Thank you. These are the partitions of my Omega2 "Pro" 's 16GB eMMC card with microSD adapter.
    I 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.
