I applied the latest update, per your instructions, then decided I'd set up my SD Card per:
For some reason, while the "block detect" command did come up with a useful output, I couldn't redirect that output to /etc/config/fstab - So I did it manually!
However, despite working through all of that, on reboot the Omega 2+ I have doesn't remember there was an SD card in the slot! I have to eject the SD Card, and reinsert it, and then the OS sees it.
Which means that I can't boot from it....
