Genode onto i.mx53 qsb

[Stefan Kalkowski]

Hi Joseph,

what u-boot version do you use? I recently run into a similar problem
when using a recent u-boot version. It had to do with a more strict
checking before unzipping. To test out whether it is the same problem
try to run the image without compressing it. Therefore, you might build
your uImage by hand:

  /usr/local/genode-gcc/bin/genode-arm-objcopy -O binary \
  var/run/tz_vmm/image.elf var/run/tz_vmm/image.bin

and:

  mkimage -A arm -O linux -T kernel -C none -a 0x70010000 \
  -e 0x70010000 -d var/run/tz_vmm/image.bin var/run/tz_vmm/uImage

If that works for you it's probably the same issue.

Regards
Stefan
