I have linux-2.6.7 running on both MPC8265 and MPC8280 based custom
boards.
Firstly, I think your problem may be that the u-boot overwrites the linux
image file during decompression, because it is placed too low in memory
(0x200000).
Try first to set your u-boot environment loadaddr higher.
0x400000 works fine for linux-2.6.7, but another thing I see is that your
linux image file is rather large (190c52 hex). My linux-2.6.7 uImage file is
f10e9 hex, quite smaller.
Has linux-2.6.8 grown so much ? or are you making the wrong image ? You
should make uImage, I guess you are aware of that.

Subject: Has anybody successfuly run linux-2.6.8-rc2 (or any
previous linu x
2.6 version) on MPC 82xx ?
Hello,
I have been told that the first linux 2.6 version, which should work on
MPC
82xx is linux-6.8-rc2 ...?
So I have cross-compiled "vanilla" linux-2.6.8-rc2 (using Cygwin with
quite
a few patches from Dan Kegel , Martin Schaffner and others to make
cross-compiling work - except for netfilter code, which doesn't
cross-compile on Cygwin and needs to be disabled, which I did) for ppc,
82xx
and created uimage (used mkimage tool from u-boot-1.1.1, which I have
built
also on Cygwin with the latest Yuli Barcohen's patch). I have loaded this
uimage onto PQ2 ADS witn MPC8270 (U-Boot version loaded on the PQ2 ADS
flash
is still 1.0.0.) and tried to run it with "bootm" - but it fails (resets)
immediately after decompressing the image ... and I do not have 82xx
back-end Jtag probe/debugger available to me to see what is happening...

Has anybody successfuly run linux-2.6.8-rc2 (or previous linux 2.6
version)
on MPC 82xx ?
If so, could you share with me ".config" file used ?
On another more general subject - does Freescale (former Motorola) has a
single focal point person who's charter is to promote Linux board support
on
Motorola development boards (aka Linux czar) - do you have his contact
info
?
I know that there were Linux OS Development Breakout Sessions SNDF (Smart
Networks Developer Forum ) April, 2004 Dallas
http://www.freescale.com/webapp/sps/site/overview.jsp?nodeId=02VS0llCc5pzMP5
51361587974
So somebody should stand behind Linux development activity at Freescale/
Motorola (both IBM and HP do have dedicated Linux Labs and people working
strictly on Linux ...) I guess ...
Thanks,
Best Regards,
Alex
