Hello
I've followed all the steps suggested above. There were no problems interacting with Linux system on test board via UART cable. It looks like Network boot and fastboot (Odroid-XU4 doesn't have USB otg port) are not supported by Odroid-XU4. After creating hw_odroid_xu build directory, adding suggested RUN_OPT to build.conf file and executing make run/log I end up with the following output:
spawn fastboot -s usb:2-1.8 boot var/run/log/uImage < waiting for device > Loading timed out Load step failed, retry. spawn fastboot -s usb:2-1.8 boot var/run/log/uImage < waiting for device >
So it appears that fastboot can't find the device. Running *$ sudo fastboot devices -l* returned no results. Probably the reason for this is that I'm connected to Odroid via UART cable. So I gave it another try, using fatload option.
1. Copied *uImage* &* image.elf* from *<build-dir>/var/run/log/* over to the first partition of my MicroSD card 2. Connected to Odroid via UART cable, powered it on and interrupted the boot sequence
then: Exynos5422 # fatload mmc 0 0x48000000 uImage there are pending interrupts 0x00000001 reading uImage
540242 bytes read Exynos5422 # bootm 0x48000000
Result:
## Booting kernel from Legacy Image at 48000000 ... Image Name: Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 540178 Bytes = 527.5 KiB Load Address: 80000000 Entry Point: 80000000 Verifying Checksum ...

image.elf gave me the same output.
Any suggestions on what goes wrong and which way to move next?

sorry, I just recognized the SoCs are not fully equal. The first Odroid XU, which we are using is Exynos 5410, and your board uses Exynos 5422. Anyway, I would follow the same approach. Additionally, you can compare memory settings and I/O memory settings of the UART within device-tree specifications of the two boards:

Hello Yevgeny Lavrov,
there is basic support for the Odroid XU regarding Genode's own kernel (base-hw). I assume you will be able to start various scenarios that only use CPU, Timers and UART on the Odroid XU4 as well, because they use the same SoC.
I would start with connecting a UART cable via the GPIO ports to your home computer, and test whether you can interact with a Linux system running on top of your test board. After that, you might play with u-boot until you can successfully boot over network, e.g., a Linux kernel. Possibly, you cannot even network boot on Odroid XU4, but have to use fastboot (via USB) instead.
Finally, you start your Genode development by creating a 'hw_odroid_xu' build directory, add some RUN_OPT variables to the 'etc/build.conf' to automatically load the setup and interact with the test board, corresponding to the method you are using (either network boot or fastboot). Here is some example for the Odroid variant we are testing nightly:
RUN_OPT += --include image/uboot RUN_OPT += --include load/fastboot RUN_OPT += --load-fastboot-device 'usb:2-1.8' RUN_OPT += --include log/serial
Then you can start some very basic example, like:
make run/log
and wait, whether you get some output, and if the test succeeds.
For a general introduction to the build environment and run-script automatisms, have a look at the Genode foundations:
https://genode.org/documentation/genode-foundations-16-05.pdfIn general, it is a good idea to first skim through this document.
Best regards, Stefan

Greetings
I would like to try Genode on Odroid-XU4. I aware that there's no support available for this ARM device yet. However, I want to give it a try, but I don't know where to start. Can you please point me in the right direction so I can find the information that I'll need to get started this task?
Thanks
