Hi
My impression from our last discussion was that your toolchain is
somehow broken as I was unable to reproduce your problems on (almost)
the same hardware
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.
As I forced my son to run on his MacMini (Intel Core Duo) only Linux and
no MacOsX (he discovered widelands and was quite happy), I had a platform
where I could install the CD with ELDK 4.0, which I had laying around.
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
PowerBook.
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
"/lib/tls/libthread_db.so.1".
(gdb) run
Starting program: /bin/simple
[Thread debugging using libthread_db enabled]
[New Thread 805422032 (LWP 639)]
root_thread_init 4[New Thread 805455088 (LWP 642)]
Program exited normally.
(gdb) quit
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.
Here are the commands
ppc_4xx-gcc -I../.. -I/home/hcu/rootfs/usr/xenomai/include -D_GNU_SOURCE -D_REENTRANT -I/net/ng/mnt/data.ng/hcu/project/vx_skin -D__XENO__ -g -DVXWORKS -c -o
simple.o simple.c
ppc_4xx-gcc -o simple
simple.o -L/home/hcu/rootfs/usr/xenomai/lib -lpthread -lvxworks
Again the same question. What versions of kernel, ADEOS-IPIPE and
Xenomai are you using.I have some problems to get the kernel booted with
the VxWorks skin emulation. I understood, that I must build the Native
and POSIX skin as modules and enable the periodic timer support with a
resonable frequency.
