Hi Everyone,

I have been trying to get the linux-2.6.20-rt3 for arch/powerpc to
boot on my lite5200b. Here are the things that I have tried so far. I
have a custom board based on the lite5200b and then the evaluation
board too.

- I have a working 2.6.16-rt29 kernel compiled using ARCH=ppc for both
these boards.

- I tried the default configs for lite5200 for both the custom board
and the EVB. Both hang at "Transferring control to Linux (at address
00000000) ..."

Device tree missing?
You need to compile it with dtc, then in u-boot use something like:
bootp; tftp 0x400000 uImage.ppc; tftp 0x600000 lite5200b.dtb
set your bootargs
bootm 0x400000 - 0x600000

- I downloaded roberts
http://www.pengutronix.de/oselas/bsp/phytec/index_en.html#phyCORE-MPC5200B-tiny
patches, but still ended up with the same result.

I read ( http://www.nabble.com/Re%3A-MPC52xx-support-rework-for-2.6.20-p7568655.html
)  that the arch/powerpc port for lite5200 works right out of the box.
Am I doing something wrong ?

The one thing I am yet to try is to do a git checkout from
git.secretlabs.ca. Unfortunately thanks to some internal firewalling
policies I still have not been able to do that.

kernel.org tree will also work with lite5200b, if you need ethernet
download fec/bestcomm patches from Grant's tree.
