All,
Anyone who cares to test usb gadget mode in u-boot, can try the gzipped image at:
http://groups.google.com/group/beagleboard/web/musb_gadget-u-boot.bin.gz
This image was built using the latest code on the omap3-dev-usb branch + the latest patches on the mailing list (that should get added to the branch soon). To read a little more about what this is doing, read: http://elinux.org/U-boot_musb_gadget_support - specifically the setting of the stdin, out, err.

Hi,
I just try to test your u-boot.bin but seem to have miss something...
because my board is not booting any more.
Here what I have done
Old version at bootup:
U-Boot 1.3.3 (Jul 10 2008 - 16:33:09)
First switch beagleboard power, remove SD and insert into SD slot of
your PC. The SD partition are mounted:
cd ~/u-boot-omap3
cp u-boot.bin /media/boot/
ls -lh /media/boot/
total 3.4M
-rwx------ 1 kapare root 701K 2008-12-18 22:36 flash-uboot.bin
-rwx------ 1 kapare root 17K 2008-12-18 22:26 MLO
-rwx------ 1 kapare root 172K 2009-01-23 14:39 u-boot.bin
-rwx------ 1 kapare root 2.5M 2009-01-19 18:16 uImage
-rwx------ 1 kapare root 20K 2008-12-18 22:30 x-load.bin.ift
sudo umount /media/boot /media/rootfs
Second remove SD from PC and insert it into beagle board.
minicom
Plug beagle board power.

......NOTHING HAPPEN!
""Reboot your board and keep the user button pressed while applying
power (see Known bugs). ""
Oups I was pressing user button and I remove the power cable 
So what should I do to fix that ?

Hi Kapare,
This happen to me once, and was that for some configuration my board
was loading the code at 82000000 instead of 80000000 as the
instructions assume. Please try to do recovery with the MMC recovery
procedure documented here:
I have actually been loading this u-boot off the MMC rather than
writing it into NAND since I keep modifying the u-boot code. I have
only written MLO (x-load) to nand, and let u-boot load off the MMC.
This gets me around the times when I do something bad to the code and
the beagle doesn't boot anymore!
-Atin
Hi,
This is what I have achieved until now!
1- Nothing changed the board is stock trying to start the Bootloader.
2- I create a script that shows the steps that I have done, see
attachment update_sd.sh
3- MLO_restore I used the one from BeagleBoardRecovery - eLinux.org
4- I could try BeagleBoardRecovery - eLinux.org ?
But I will wait for your suggestions.
Regards
kap

Hi Again,
I encourage you to sign-up on the mailing list to avoid having all of
your messages moderated. You can sign-up and opt for no e-mail.
I try multiple variation with those event just the MLO_restore only.

sudo cp /home/kapare/beagleboard/sd/boot/MLO_restore /media/boot/MLO
sudo cp /home/kapare/beagleboard/sd/boot/MLO_revb /media/boot/MLO
If you overwrite the MLO_restore, then it won't work. MLO must be the
first file copied after freshly formatting the SD card per the
instructions. You cannot alter it after you copy it or it won't
work. You'd need to start over again by formatting the card again.
sudo cp /home/kapare/beagleboard/sd/boot/musb_gadget-u-boot.bin /media/

boot/u-boot.bin
sudo cp /home/kapare/beagleboard/sd/boot/u-boot.bin_autoflash /media/
boot/u-boot.bin
I think you only want to copy the _autoflash version if you are trying
to recover your board.
sudo cp /home/kapare/beagleboard/sd/boot/flash-uboot.bin /media/boot/u-
boot.binI see the ...40T... but no output about MMC like in thehttp://elinux.org/BeagleBoardRecovery#MMC_recovery

If you aren't seeing something like the above, then the MLO setup
didn't work or you aren't holding the USER button when you apply
power.
-------
So you said that "You need to make sure your beagle boots off SD since
the version in NAND is written into the wrong spot for your config."
This mean that my beagleboard is not booting likeUSB -> UART -> MMC -> NAND
but always
NAND -> USB -> UART -> MMC
Actually, the 40T tells you that UART boot was attempted, so you
aren't booting directly from NAND flash.
I think I'm missing something and it is very stupid! Or maybe that my
MLO_restore that I copy was not ok!?From my other attempts I found that after Formatting I need to
"Unplug, and replug in your SD card, and it should now automount the
two partitions that you created. "
You should only do that after performing a 'sync' to make sure the
cache is flushed on your system.

I always copy MLO_restore first and did not overwrite it. I just cut
paste the command that I used to show what I have tryand only one MLO
each try.

Ok The USER button was pressed and hold each time, so this is what I
am now thinking that my setup did not work. But the question is what I
did wrong?

So you mean that I should do a sync just before doing sync, umount
then unplug? to be sure that file systems buffer are flush. If I don't
call sync before calling umount can this be a cause of my problem?
I will go on the chat to continue that discussion....

Finally I fixed the board and had the chance to test the Atin u-
boot.bin with usb :))
