Hello,

I spent some hours compiling various *vanilla* flavours of 2.6.31 for
c7x0, up to 2.6.31.3.
The kernel boots just fine from SD/CF using kexec(boot) but hangs
immediately if launched from nand.

I double-checked the .config and I'm sure I've had the same mtd
options as in 2.6, so it should just boot...
Last lines on console are from bootloader: *** Jumping to Linux ***
and then nothing...no leds activity nor reboot after flash.

What's interesting is that Tosa too doesn't boot from nand with this
kernel, so possibly is the same issue.
Any idea, any floating patch?

Regards

Andrea

I'm using kexec, exclusively :-(.

Hi Andrea,

I had no time to look into this yesterday, but browsing through the mailing
list I find:

http://www.spinics.net/lists/arm-kernel/msg75900.html
http://www.spinics.net/lists/arm-kernel/msg75829.html

I hope one of these help ;-)

Cheers,
cortez

Few days ago I sent a patch called "Zaurus: Fix NAND Flash OOB layout
for Borzoi". Maybe something similar affects Tosa. However quick look
into the code does not show any apparent problem.

Old implementation: Only driver in drivers/mtd/nand/sharpsl.c.

New implementation: Platform definition + drivers/mtd/nand/sharpsl.c.

In my case it attempted to boot, but I seen lots of NAND errors on the
beginning of the boot.

Not here on c7x0, if I copy the kexecboot-kernel on SD/CF and boot
from there it seems to find and respect the mtd partitions...

I personally did not test on tosa: Yuri said tosa boots with 2.6.30
but not 2.6.31.
I'll have to try with 2.6.30 on c7x0 too.

Regards

Andrea

I've tested .31 on tosa some time ago. Kernel booting just hangs in the
middle.

BTW, what about create some group on google or project on linuxtogo to
connect all active zaurus users and developers. We are still have some
unresolved troubles (power management for clamshells, wifi for tosa). IMHO,
it would be great thing for collaboration.

It may be an useful idea. Especially if there will be any way to contact
other people that may be able to test patch on other devices.

Do you think that it makes sense to create a git tree for Zaurus
(probably based on Eric's tree + Eric's fix tree) and then push tested
stuff? (Well, I am not yet so familiar with git.)

I am thinking about yet another project: Matchbox2. The original site is
dead, maintainers don't respond and I push each fix as a patch directly
to OE. It already works nicely on my Zaurus.

Yes, something like that would be cool.
Well, if the ammount of outstanding patches gets big and if someone is
willing to maintain it, why not, but for now, I guess using Eric's
tree makes sense.
