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.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:
