Hi guys, i'm trying to compile my personal u-boot for multiplexing pin
reasons.. The problem is that i can't find a working source code, when
i compile u-boot.bin with a source it doesn't start my beagle, with
another it starts but with no usb working and wrong dvi resolution and
all red. I'm loosing my hope, it's about a month that i'm working on
it.. Can anybody help me, telling me the right git and possibly the
modifies to do to compile a working u-boot? (like that's in
xmc_4_25.img validation image).
Also i've read this:http://groups.google.com/group/beagleboard/
browse_thread/thread/560a08274cc267c8
but when i'm on the git.angstrom-distribution.org how should i move?
How to use what it's there?
Hey anyone answer to me? I'm desperate, i'm trying to do this for
work..
The mainline u-boot at http://git.denx.de works (to the best of my knowledge). There are some features added in OE for the validation image, but if you are interested in building your own u-boot I suggest starting from the mainline. I’m skipping some generic steps, but you can essentially ‘make omap3_beagle’.
Hi, from denx.de i can't get it work.. It give me an error2, seems the
compiler (codesourcery) isn't able to find a .depend to make some
work..... I don't understand.
From here: http://gitorious.org/beagleboard-validation/ i'm able to
build successfully an u-boot.bin image, setting resolution from
boot.scr but i have 2 problems: the screen display all color similar
to red and the 4 usb ports are not powered, so i can't use any
keyboard and mouse. is there any change to do into source to have sub
and right color working?
This is the error i get:

I was getting the error when I git clone the u-boot-main
I tried downloading from here - and it seems to compile fine.- haven't
tried running the built image on the board yet.

I will try, thank you!!
It doesn't start.. From console it prints at last:
OMAP3 Beagle board + LPDDR/NAND
I2C: ready
DRAM: 512
and here it stuck..
But this u-boot doesn't have beagle xm c support?

Choosing a known-good release from the mainline is a good strategy.
That is much better than trying to pick up one of the odd-ball working
branches used to generate patch sets.

The version build with the above patches has is what is most
frequently used by myself and many others working on the project.

I believe you may have better luck if you apply this pending patch:
http://patchwork.ozlabs.org/patch/107678/
I haven't tried it, they just seem to be reporting/fixing a similar issue.
Hi, i've tried to apply the patch with patch -p0 < "patch".patch but
it gives me this:

Ok i've applied the xm support patch successfully to boot 2011-06 but
when booting it stuck at the same point (DRAM: 512)
I know this commit works on xM Rev C:
http://git.denx.de/?p=u-boot.git;a=commit;h=56fa45d58116f86f343a9c45ce6d1110f50b8d70
To get USB working in u-boot, I disabled caches in the config, but USB
is the only thing I know that breaks. You might also want to extend
the timeout duration for MMC, but I haven't seen that it is required.
For MLO, I know this commit works:
http://gitorious.org/x-loader/x-loader/commit/fca7cd29b6821df3e7d8c4369522f2a3d01a5d7b
Sure, you can try to reproduce what is in the April 25th image and I
can help you do that (the easiest way is to actually use
OpenEmbedded), but if you want a solid u-boot code base to build from,
get onto the mainline development tree. v2011.09 will be released
soon and should be pretty good for BeagleBoard and BeagleBoard-xM.
How to disable cache in u-boot? I must modify some code ore what?
It is a setting in the configuration header file. Here is the patch:

I am testing xM Rev. C on 2.6.39. After patching, it works with usb
hotplug only. If I reboot, kernel log shows usb info, but it is not
accessible in /media/sda, unless I unplug and plug.
