Has anyone 2.6 kernel with Xenomai and MPC5200 Lite running?

Has anyone 2.6 kernel with Xenomai and MPC5200 Lite running?

[Matthias Fechner]

Hi,

I have here a MPC5200 Lite (IceCube/Freescale Lite 5200) and tried to
get Xenomai running.

If I use the 2.6 kernel from denx the board boots fine but I am not
able to patch the kernel with the adeos patch (adeos-patch is for
kernel 2.6.18) and the kernel from denx is 2.6.19rc4. I checked the
changes and they are to much for me to adapt it.

What I need now is a patch for kernel 2.6.18 to get all the MPC5200
stuff running (priority has the networkchip) or a adeos patch for the
denx kernel 2.6.19-rc4.

Can anyone help me here, please?

Best regards,
Matthias

Note that we explicitely do NOT support the MPC5200 in this tree yet.

Then just check out the 2.6.18 version of the tree.  This  is  a  git
repo, so seeking to any version you like is a matter of seconds.

You do not want this, if you're on a MPC5200. I repeat, this  is  not
supported.

hm, I did it but was not successfully. What I did was:
git clone git://www.denx.de/git/linux-2.6-denx.git linux-2.6-denx
cd linux-2.6-denx
git checkout -b private2.6.18 v2.6.18

Now I had kernel 2.6.18 but without network :(

Is that wrong? Sry but git is completely new for me.

ok, that is clear but if the kernel boots fine on the board with
network and I am able to patch it with Xenomai I can live with it.

This will give you the  exact  2.6.18  kernel.org  tree  without  any
extensions  / modifications. It has even less support for the MPC5200
than our tree, wher eit is unsupported.

> Now I had kernel 2.6.18 but without network :(

ACK. The kernel.org tree does not include Sylvain's patches.

You mean, you don't care about reliability?  Umm...  then  you  don't
need Xenomai, either.

how can I checkout kernel 2.6.18 with denx improvements?

I need the system only for development, the targetsystem will run on
another board :)

run gitk and check where our tree was megred with the Linus tree after
the v2.6.18 release - you will find that it's commit ID

I'm not talking about a specific board, but about MPC5200 in general.

Yup, there exists patches for all the functionality that you're
looking for.  You can find them if you search the list, but I'll send
you a link to a git tree with all those patches in it later tonight.

you maybe mean:
http://gitbits.246tNt.com/gitbits/linux-2.6-mpc52xx.git

I tried that repository but here I was not able to patch the tree with
Xenomai.
But if you have another link it would be a pleasure for me to receive
the link :)

Take the patchs off that link (bestcomm branch), and apply them on a
fresh/recent
tree, that should work. (that is, clone a official tree, then pull from
the above link
and merge the two).

There is work in progress for the arch/powerpc port but it's not done yet.

I also tried to get Sylvain's patches working on 2.6.18 and gave up 
rather frustrated. They do not work "as is" :-(. I can offer you a 
solution for Xenomai on 2.6.17, if this is an option for you. That's 
what I got working for development.

that would be fantastic.
I only need kernel 2.6 running on MPC5200 with xenomai.
I can give you access to one of my servers if you want to copy there
the kernel.

Matthias

Some time ago I got the MPC5200 patches from the Pengutronix's OSELAS
project working for DENX Linux 2.6.17. In the meantime they have update
to 2.6.18. Take OSELAS.BSP-Phytec-phyCORE-MPC5200B-tiny-4.tar.gz from
http://www.pengutronix.de/oselas/bsp/phytec/download/phyCORE-MPC5200B-tiny/, 

unpack it and apply the relevant patches from the kernel-patches-target
diretory to linux-2.6-denx#v2.6.18. I think the following patches should
be sufficient (in that order):

   fec_mpc52xx_bestcomm.diff
   fec_mpc52xx.diff
   drivers_serial_mpc52xx_uart_fix.diff
   mpc5200_physmap.diff

You can find the most recent Xenomai patch 2.6.18-ppc-1.05.00 at
"ftp://ftp.denx.de/xenomai". I'm going to test them later today with 
Xenomai.

Good luck.

Wolfgang.

ok, my boards boots fine after that.

I applied now everything and Xenomai builds fine.
I configured now my kernel, build it but the board do not boot or at
least the console has gone.

Which bootargs you use in u-boot to boot the Xenomai kernel?
My bootargs are:
bootargs=root=/dev/nfs rw
 nfsroot=192.168.0.151:/usr/local/eldk/ppc_6xx
 ip=192.168.0.101:192.168.0.151:192.168.0.151:255.255.255.0:icecube::off
 console=ttyPSC0

You can find what I did on:
http://wiki.idefix.fechner.net/index.php/Xenomai

Thx for tips.


Best regards,
Matthias

Yup, that's the tree I was referring to; and yes you would need to do
some work to get all the patches to play nice together.  :)

Unfortunately, I've had some technical issues on my end, so I haven't
been able to get a tree together for you yet.
