hm. There doesn't seem to be a big difference to mine. If you are
interested, take a look at the install target in the Makefile in:
https://gitlab.com/c-mauderer/rtems-simulation-environment
It's basically just building the same stuff. Differences:
I use the waf based build system for the BSP. But that shouldn't really
matter at the moment. But note that you might have to switch somewhen in
the near future because it is planned to remove the old autoconf /
automake based build system.
Beneath that I use a qemu build from the upstream sorces because the
version from RSB doesn't build cleanly on Arch Linux (something about
docs). But I tried it with the binary build by RSB and that works too.
I'll think a bit about it and let you know when I find something other
that might be a problem. But at the moment, I'm running out of ideas.
Maybe you can try to attach a gdb to your qemu and see whether the
application runs and only doesn't produce output?
Best regards
Christian
