We tried to run Xen > 4.4 on the Arndale Octa board. Xen 4.4 only supports the Arndale 5250. AFAIK, the octa has a similar layout as 5250. Porting Xen on the board should not be too difficult. I know there is some people who are working on porting Xen to the odroid xu which also have an exynos inside. > We have successfully to run Ubuntu on that board by customizing the UBoot.

There is no documentation updated to boot from the SD card. Regards, -- Julien Grall
