    @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.

    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 😉

    @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.

    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.
