Are you linking with the correct libc ? If you have the LC part you do
not have an FPU. If your linker command or tools are not correct the
default 68020 library links and that requires a FPU. This always trips
in the printf function first.
A simple check is:
m68k-rtems4.11-objdump -d myapp | grep fmovemx
