@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# Omega2+ FW omega2pro-v0.3.2 b218 with an 8GB microSD card and a 1GB USB pendrive root@Omega-99A5:/# cat /proc/partitions major minor #blocks name 31 0 192 mtdblock0 31 1 64 mtdblock1 31 2 64 mtdblock2 31 3 16064 mtdblock3 31 4 1535 mtdblock4 31 5 14528 mtdblock5 31 6 6720 mtdblock6 179 0 7676928 mmcblk0 179 1 7672832 mmcblk0p1 8 0 997376 sda 8 1 997344 sda1 root@Omega-99A5:~# fdisk -l Disk /dev/mtdblock0: 192 KiB, 196608 bytes, 384 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock1: 64 KiB, 65536 bytes, 128 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock2: 64 KiB, 65536 bytes, 128 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock3: 15.7 MiB, 16449536 bytes, 32128 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock4: 1.5 MiB, 1572352 bytes, 3071 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock5: 14.2 MiB, 14876672 bytes, 29056 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mtdblock6: 6.6 MiB, 6881280 bytes, 13440 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/mmcblk0: 7.3 GiB, 7861174272 bytes, 15353856 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x15d70756 Device Boot Start End Sectors Size Id Type /dev/mmcblk0p1 8192 15353855 15345664 7.3G b W95 FAT32 Disk /dev/sda: 974 MiB, 1021313024 bytes, 1994752 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x0073cd33 Device Boot Start End Sectors Size Id Type /dev/sda1 63 1994751 1994689 974M e W95 FAT16 (LBA)

@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.

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.

@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.
