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
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.
