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

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