Here's what I've done so far:

$ export CROSS_COMPILE=ppc_6xx-

Get the sources:

$ git clone git://git.denx.de/linux-2.6-denx.git
$ export KDIR=$PWD/linux-2.6-denx

$ svn co http://svn.gna.org/svn/xenomai/branches/v2.4.x xenomai-2.4.x
$ export XDIR=$PWD/xenomai-2.4.x

$ cd $KDIR
$ git checkout origin/DENX-v2.6.25-stable
$ git checkout -b origin/DENX-v2.6.25-stable


Prepare the kernel for Xenomai:

$ cd $XDIR
$ scripts/prepare-kernel.sh --linux=$KDIR --verbose --arch=powerpc

The following will appear:

Adeos patch [default
/home/user/linux-2.6-denx/xenomai-2.4.x/ksrc/arch/powerpc/patches/adeos-ipipe-2.6.25-powerpc-DENX-2.2-03.patch]:

Just hit enter.


Configure and create the kernel enabling RT-Socket-CAN:

$ cd $KDIR
$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
... enable RT-Socket-CAN and MSCAN driver ...
<*> RT-Socket-CAN, CAN raw socket interface
[*]   Enable debug output (NEW)
[ ]   Enable TX loopback to local sockets (NEW)
(1024) Size of receive ring buffers (must be 2^N) (NEW)
(4)   Maximum number of devices (NEW)
(16)  Maximum number of receive filters per device (NEW)
< >   Virtual CAN bus driver (NEW)
<*>   MSCAN driver for MPC52xx
[*]     Enable CAN 1 (NEW)
[*]     Enable CAN 2 (NEW)
(66000000) Clock Frequency in Hz (NEW)
Pin Configuration (CAN 1 on I2C1 pins, CAN 2 on TMR01 pin
...


Build the image:

$ make ARCH=powerpc uImage

$ cd $XDIR
$ ./configure --host=ppc-linux --prefix=/root/xenomai
$ make

After this 'make' instruction, the following echoes:

I don't know what to make of it.

The ELDK is up and running, by the way.

Thanks in advance,

Marco Antônio Possamai

You should read configure output, it is probably instructive. Notably,
it should tell you that there is no such compiler as ppc-linux-gcc,
since your compiler is called ppc_6xx-gcc, you should pass
--host=ppc_6xx to xenomai configure script.

alternatively, you can pass CC=ppc_6xx-gcc on configure command line.

This is all documented in README.INSTALL

And here you see that xenomai makefiles are using gcc, which is wrong.
