Hi,

I'm trying to port sel4 into ODROID-XU4 by following the wiki ( https://wiki.sel4.systems/Hardware/odriod-XU).

So far I can successfully enable HYP mode as indicated by [ 0.198398] [c0] CPU: All CPU(s) started in HYP mode. [ 0.198433] [c0] CPU: Virtualization extensions available.

as well as generate sel4test-driver-image-arm-exynos5 image.

However, we cant do fastboot in XU4 since it doesnt have usb otg. Thus, I followed booting from sd card from https://wiki.sel4.systems/Hardware/General-ARM and copied the image into the first partition of sd card and do the following:

Exynos5422 # fatload mmc 0 0x48000000 sel4test-driver-image-arm-exynos5 Exynos5422 # bootelf 0x48000000

and here's the output:

## Starting application at 0x41000000 ...

Is it expected? or am I doing something wrong? Any help would be appreciated.
