[HOWTO] 5- Run RTEMS on QEMU

If you're a QEMU fan, and want to give it a try running RTEMS, then this post is for you. Make sure you've followed all of the previous instructions described here [1] [2] [3].

There are some RTEMS sim scripts you can use that do the magic of running simulators for you (but then you'll have to get sim-scripts repo and run it from there). I won't go through sim-scripts here, just do it manually as it's just one command! For more instructions you can peek into the or1ksim README file.

$ vim $HOME/development/rtems/src/rtems/c/src/lib/libbsp/or1k/or1ksim/README
or1sim BSP README


Run

Let's run some interesting sample app called capture now that you can have some interactive fun with.
$ qemu-system-or32 -serial mon:stdio -serial /dev/null -net none -nographic -m 128M -kernel $HOME/development/rtems/build/or1k-rtems4.11/c/or1ksim/testsuites/samples/capture/capture.exe

RTEMS or1ksim/capture.exe running on QEMU

You can try running other samples under sample directory.
