Hello James,

are you aware that the '-S' option on your qemu call freezes the CPU at
startup. This is useful if you want to connect a debugger (gdb) to the
qemu session.

You can try one of the following:
- connect a gdb to qemu and start the application through it
- start the cpu using 'c' on the monitor (see
https://en.wikibooks.org/wiki/QEMU/Monitor for more details)
- remove the '-S' option

Kind regards

Christian Mauderer
