Thanks for the quick response. I'm currently using 2.6.24 ARCH=powerpc
on the Lite5200b. I just searched for an obvious patch but it is unclear
to me what patch(es) I should take at this point.
Can you direct me to the patch(es) I need? Again, thank you.
As a first try you can build Socket-CAN out of tree by just downloading
the SVN trunk repository as described here:
http://developer.berlios.de/svn/?group_id=6475
Then go to trunk/kernel/2.6 and type:
$ make ARCH=powerpc KERNELDIR=<path-to-kernel> \
CONFIG_CAN_MSCAN=m CONFIG_CAN_MPC52XX=m
You need the following modules on your target:
drivers/net/can/*.ko
drivers/net/can/mscan/*.ko
There is a script to create kernel patches, but I don't known if it
works right now (there have been some issues recently). Please ask on
the Socket-CAN mailing list.
Wolfgang.

I think I'll get it going at some point, but if anybody has or knows
of
an mscan driver for the mpc5200 can you alert me?

The Socket-CAN core is part of the official kernel since 2.6.25.

Thanks,

We are developing with an 8248-based platform, and we have a vendor

turn up any horror stories, although the processor does have some PCI
errata listed. Does anybody have any practical experience using PCI
on
the 8248 or similar that they can share with me? Thanks.
Make sure that you park the bus on PCI, and elevate PCI's arbitration
priority. See fixup_pci() in arch/powerpc/boot/cuboot-pq2.c.
I haven't had a problem with PCI DMA when that is done, though I
haven't
done significant stress testing.
