Yeah, i biseced it down to (and reverted)
"ENGR00141363-ARM-imx53-clock-change-di0-clock.patch" from both
freescale's 2.6.35 11.09.01 bsp, which fixes the uart clock
corruption..
I brought the patch over to the
LTIB/BSP branch and it worked like a champ. I can now boot multiple
kernels from the recent u-boot without the serial port messing up. Life
is a little better now.
So all my script does, it checks out 2.6.35.3 from the "linux-stable"
tree which is combination of torvalds tree and all the stable
branches.. Then i pull freescale's patch set, and since i have the
common ancestory it all merges nice and clean.. Then i also revert one
commit to fix the serial output..
so simple:
git checkout v2.6.35.3 -b new-branch-based-off-2.6.35.3
git pull http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git
imx_2.6.35_11.05.01
git revert --no-edit <some sha that i can't remember for:
ENGR00141363-ARM-imx53-clock-change-di0-clock.patch>
OK. Clear as mud for me right now. :-) This will give me something to come up to speed on.
humm, strange which usb port? otg/ehci, i haven't see that one. btw is
this the new "R" board, next to the ddr, there should be a silkscreen
with the model number with a "-R-" or something..
Yes, this is the new "R" board. I guess it includes a few
"enhancements" to make our lives a little more exciting. I've included
the tail end of the boot messages to the email if you want to look at
where the 'usb wakeup is here' messages are coming from.
Now that I have a new u-boot that I can build working nicely with the
Freescale BSP kernel, I think I now have enough to begin work on the a
stable Debian install for myself. I plan on ripping into the Ubuntu
Lucid demo that came with my iMX53 QSB and work on replicating its
functionality with a Debian install. It has working Ethernet and USB
(at least for keyboard/mouse), but sata doesn't seem to be working.
Something frustrating is that I can see that Ubuntu kernel was built
from the same source tree as the LTIB/BSP sources, but they don't seem
to provide the config file for the kernel. I can't tell exactly how
they configured the kernel to properly activate all the devices. I
don't know of a way to get the kernel configuration from the running
Ubuntu system either. Hopefully I can find some hints on the Internet.
Thanks again.
