Assuming that you are building a debug version of the kernel, the next line that should be
printed is "Bootstrapping kernel".
Are any changes required for the serial port driver?

Subject: [seL4] Problem porting sel4 into XU4
I'm trying to port sel4 into ODROID-XU4 by following the wiki
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 ...
ELF-loader started on CPU: ARM Ltd. Cortex-A7 r0p3
ELF-loader started on CPU: ARM Ltd. Cortex-A15 r2p3

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