I've run OKL4 on skyeye under gdb, but that was for the purpose of
debugging skyeye, not OKl4 :-)  Currently there's no explicit support
for debugging OKL4 via gdb.

If you look at the skyeye.conf we provide at
http://wiki.ok-labs.com/downloads/release-3.0/skyeye.conf , you'll see
there are two lines commented out at the end.  If you uncomment one or
the other of those you get debug trace out of skyeye The first one gives
an execution trace.  You can then cross-check with the output of
arm-unknown-linux-gnueabi-objdump -DC on image.elf to trace the program
execution.

Hope that helps somewhat,
