Hi,
I am trying to boot a genode uImage (tftp,bootm) but gets ATAG not compiled in. Do I need to patch out that error from u-boot , or is there another workaround?
A little follow up. I used bootelf -p address. That started the kernel but end up in:
Kernel: Unknown cpu exception EC=0 ISS=0 ip=0xffffffc000040cb
It is stack management code.
I modded my cmd/boot.c to allow booting aarch64 binaries and cloned down a new Genode source tree. Built run/log and started it with "go 0x40010000". It worked once.. I changed ram size and uart (to match my board) and try booting again. Nothing on serial. Then I tried to echo a char right in the starting point crt0.s, it worked I get that char on serial. OK .. I recloned a new source tree , but same results.
I can't get bootm to work even after removed the atag requirement.
I would be very happy if someone can explain what happens.
