Steps to try a genode image on Wandboard

Fri Dec 1 18:25:25 CET 2017

Thanks Helmuth.

Somehow i got confused with the word "run" that i thought it will run some emulator.

Now i got it. I don't need all the packages.

I tried "make KERNEL=hw run/log" and i got an uImage since i already added RUN_OPT += --include image/uboot

Now I can take care of loading the images in the board.

Hello Kumar,

You're on the right track, but the command above tries to build
*everything* you enabled in REPOSITORIES. For a simple scenario, you
have to run a so called "run script" by

  make KERNEL=hw run/<script name>

This seems a strange error in the RUST library, but we may just ignore
it as you seem to not depend on RUST.

I'd recommend to just use our most simple scenario which boots a
minimal Genode system including a test that logs some output (via
serial line). Please run

  make KERNEL=hw run/log

which produces

  var/run/log/uImage: u-boot legacy uImage

Unfortunately, my expertise comes to an end here, but I expect you
know how to boot the image on the board.
