This seems to no longer work. If I start it with

qemu-system-ppc -M prep -cpu 604 -bios 
./powerpc-rtems5/c/qemuprep/lib/libbsp/powerpc/motorola_powerpc/qemu_fakerom/qemu_fakerom.bin 
-nographic -no-reboot -kernel 
./powerpc-rtems5/c/qemuprep/testsuites/samples/ticker.exe

it outputs nothing.

If I start Qemu and wait for GDB

qemu-system-ppc -M prep -cpu 604 -bios 
./powerpc-rtems5/c/qemuprep/lib/libbsp/powerpc/motorola_powerpc/qemu_fakerom/qemu_fakerom.bin 
-nographic -no-reboot -kernel 
/build/git-build/b-any/powerpc-rtems5/c/qemuprep/testsuites/samples/ticker.exe 
-s -S

and then load the ELF file via GDB it outputs a bit and then crashes:
