As I forced my son to run on his MacMini (Intel Core Duo) only Linux and no

I could install the CD with ELDK 4.0, which I had laying around.

I think I really have to reactivate my old Walnut board to have common
platform to test with Wolfgang Grandegger.
It would make more sense to use the ELDK4 for comparison. I don't think
it depends on the hardware.
After some setting up of my environment and tweaking my scripts to work with
ELDK (e.g. adding --host=ppc CC=ppc_4xx-gcc to my xenomai/configure) I ended
--host=ppc-linux is already enough with CROSS_COMPILE=ppc_4xx- set.
up with a nice environment and rootfs with much more precompiled programs
than I had ever before. Debugging on the platform is now as good as on my
My situation is now as follows:
- ELDK 4.0 installed on Debian Etch MacMini
- Using ELD 4.0 rootfs ppc_4xx
- compiled the kernel uImage, modules, xenomai using ppc_4xx-gcc
(but NOT adding any -mcpu=40x flag to the compiler)
The trap 0 in /proc/xenomai/fault seems to count on each invocation of simple
0: 51 (Data or instruction access)
gdb however no does not show anything abnormal, as it says now
This GDB was configured as "ppc-linux"...Using host libthread_db library

Program exited normally.
Though I am still puzzled.
Could you please send me your Makefile or the compile command to make
"simple", then I would give it a try on my setup.
