Hi Bernhard
It does not seem to be a network or usb problem. Clearly the uboot is
loading the image from TFTP server. Why do you use two bootm calls, if
you only load the uImage in address 0x70000000?
When uboot is usesd to boot some operating systems like android or other
linux distributions bootm can be used as:
bootm $(kernel_addr) $(ramdisk_addr)
But this only can done if there are loaded on memory the kernel and the
ramdisk.
In this case GenodeOS don't use ramdisk, it uses only kernel image.
I think that the problem with Genode can be the image format. As Alexy
Gallardo explains we have tested the Odroid-U3 with the Odroid-X2
support, but we boot the image with the bootz (at address 0x41000000)
command because we use a zImage format created with the raw_image script
that him attached to you. Your uboot seems to don't have this command
(bootz), maybe it can be enable on uboot compilation.
Now i'm not in work to see the source of Uboot that we are using, but
take a look on this Uboot project with support to Odroid-X2 and
Odroid-U3.:
https://github.com/dsd/u-boot
Have you tried boot the elf image with bootelf? Or have you tried to
boot the same image from an storage device to test it first and then
move it for the tftp?
Best regards
