Hi Alex, Thanks for your reply. I'm not really familiar with serial port. How can I tell if the config in https://github.com/seL4/seL4/blob/master/src/plat/exynos_common/io.c needs changes? This is the serial cable I'm using: http://odroid.com/dokuwiki/lib/exe/fetch.php?cache=&media=en:others:usb_uart_for_odroid.png http://odroid.com/dokuwiki/doku.php?id=en:usb_uart_kit Best, Oak On Thu, Apr 14, 2016 at 5:23 PM, Alexander Kroh <Alexander.Kroh@nicta.com.au

Hi Oak,
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? https://github.com/seL4/seL4/blob/master/src/plat/exynos_common/io.c

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.
