Hi Per-Erik,

I found your message at
http://lists.ozlabs.org/pipermail/linuxppc-dev/2007-December/048539.html
back from Dec 2007.

Have you managed to run Linux on phyCORE-MPC5554 since then?

Regards,

Linux on Freescale e200

[Per-Erik Johansson]

Hi

I'm wondering if someone has ever tried to get Linux running on a
Freescale e200 core?
I found a patch to the Linux kernel from back in 2005:
(http://linux.derkeiler.com/Mailing-Lists/Kernel/2005-06/5731.html)
And it is listed as a processor type in Linux-2.6.23.11
I know that there has been some confusion about e200 and e500 cores, old
e200 renamed to e500, but from what I understand the e200 core now listed
in the kernel is the one currently being used in MPC55xx

I'm having a MPC5554, e200z6 core, that I'm supposed to get Linux running
on (master thesis) and any pointers and tips are appreciated.
Just finished porting/tweaking the Redboot boot loader, and I'm now moving
on to the Linux (porting?) part.

Cheers
 Per-Erik

I'd suggest looking at getting u-boot running instead since that's we  
use on the majority of freescale PPCs.

We did a port a while back to the e200.. so most of the basic bits  
should be there.  There might be some bit rot from its like of usage.

What peripheral set are you looking to get working on the 5554?

Had a look into UBoot at first but didn't find any port for the
MPC55xx/e200, so when we stumbled upon a "working" ecos/redboot port we
went with that..
Do you know where I could find the uboot port for the e200?

We have phycore dev. kit
(http://www.phytec.com/products/rdk/PowerPC/phyCORE-MPC5554.html)
Just supposed to get it up and running, so peripherals will just be
serial, ethernet and maybe CAN.
