beagleboard recovery take 2

[2013-03-06 update]:
after a few years of letting things rot, I just managed to pick up my old binaries and gave it a dry run:
https://github.com/nmenon/beagle-recover has the original working binaries since the google groups link no longer work. NOTE: I HAVE NOT TRIED WITH ANY OF THE LATEST SOURCES. I do not have plans to do so in the future as well  - an quick try indicated things are broke :(

[Original post]

http://groups.google.com/group/beagleboard/web/beagle_recover.tar.bz2 has the recovery package ready to go for ubuntu 8.04 32bit OS: download this, run sudo ./recover_beagle.sh - as shown in the video... Steps summary:
1. first shutdown the board.
2. run 'sudo recover_beagle.sh /dev/ttyUSB0' in a terminal -> you need
super user permissions(sudo permissions) to run this script.
3. Keep the pushbutton S1pressed while powering on the board -> there
are two white push button switches, use the one closer to the edge of
the board
NOTE: if your nand is completely erased, the above step wont be
needed, but what the heck, use it for preventing all kind of cases
where you have an MMC card/partly corrupted nand etc..
4. Once the terminal starts downloading, you can remove ur finger off
the S1 switch ;)..
5. wait a bit for files to reach and be flashed :).. the script should
exit happily once it is done.

With u-boot-v1 in mainline arm repo, here is take two of the same.. this time with a script and a non-Oscar winning video:

On my ubuntu 8.04 32bit OS PC, here are the steps I did.

------------- Build Steps ----------------
$git clone git://gitorious.org/x-load-omap3/mainline.git xloader
$git clone git://git.denx.de/u-boot-arm.git
$git clone git://git.denx.de/u-boot-v2.git
$git clone git://github.com/nmenon/omap-u-boot-utils.git


$alias mymake='make -j2 CROSS_COMPILE=arm-none-linux-gnueabi- V=1 ARCH=arm'
$cd x-loader
$mymake omap3530beagle_config;mymake
$wget "http://beagleboard.googlecode.com/files/signGP.c"
$gcc -o signGP signGP.c
$./signGP x-load.bin 0x40200800
$cd ../u-boot-v2/
$mymake omap3530_beagle_per_uart_defconfig; mymake
$cd ../u-boot-arm
$mymake omap3_beagle_config;mymake
$cd ../omap-u-boot-utils
$make;make usb
$mkdir -p ../beagle_recover/target_files;cd ../beagle_recover

$cp ../omap-u-boot-utils/pusb ../omap-u-boot-utils/pserial
../omap-u-boot-utils/ukermit ../omap-u-boot-utils/ucmd .
$cp ../u-boot-arm/u-boot.bin target_files/u-boot-v1.bin
$cp ../u-boot-v2/uboot.bin target_files/u-boot-v2.bin
$cp ../xloader/x-load.bin.ift target_files/x-load.bin.ift

------------- Flashing Steps ----------------
$TTY=/dev/ttyS0
$sudo ./pusb -f ./target_files/u-boot-v2.bin
Connected just the USB cable to the board with the user switch S1 pressed.
$./ucmd -p $TTY -c "loadb -f /dev/ram0" -e "bps..."
$./ukermit -p $TTY -f target_files/u-boot-v1.bin
$./ucmd -p $TTY -c "go 0x80000000" -e "serial";./ucmd -p $TTY -c "help" -e "#"
$./ucmd -p $TTY -c "nand erase" -e "#"
$./ucmd -p $TTY -c "nand write.i 80000000 80000 80000" -e "#"
$./ucmd -p $TTY -c "loadb 80000000" -e "bps..."
$./ukermit -p $TTY -f target_files/x-load.bin.ift
$./ucmd -p $TTY -c "nandecc hw" -e "#"
$./ucmd -p $TTY -c "nand write.i 80000000 0 80000" -e "#"


The following step is optional if you want to remove the autoboot.
$ ./ucmd -p $TTY -c "setenv bootcmd;nandecc sw;saveenv" -e "#"


The attached tarball contain prebuilt images, and you can also use a
script recover_beagle.sh which is part of the tgz attached.
