Hi Gordan,
I've tried to use the latest R-Pi image on SD card and boot from dreamplug but
it didn't work (it doesn't boot the kernel). It seems this is a uboot problem
but there maybe other issues ahead.
I wonder if you could help with writing a guide; there are a lot of people with
dreamplug out there interested in booting RSEL from internal or SD card.Install

This is what I did. I downloaded/extracted dreamplug rootfs, kernel,
modules/firmware. Then I downloaded latest R-Pi image and I did dd on external
SD card. I then copied all the dreamplug kernel (uImage) and initrd related
files to the boot folder of R-Pi rootfs. I copied contents of modules and
firmware folders into corresponding folder inside /lib of R-Pi dreamplug. I
changed the fstab entries for / and /boot to /dev/sdb2 and /dev/sdb1
respectively.
Finally, I set the uboot variables as below (i followed the example of Fedora
18 guide for dreamplug)Architectures/ARM/F18/Installation - FedoraProject

The most recent one. The older ones are mostly there for reference and
shouldn't be used.
