Hi, I have bricked my beagle board trying to install musb gadget u-boot in NAND.

Recovery from SD card doesn't work, no matter what I do, following http://elinux.org/BeagleBoardRecovery. I don't even get the ....40T...... string on minicom (1152008N1, on /dev/ttyUSB0 using FTDI serial USB converter). I tried pressing user button on powerup, using USB or DC supply power, etc .. to no avail. Previously working SDcards don't work anymore, and reformatting from scratch, using MLO_restore written first on the SD,  etc .. doesn't work either. Hence I'm left with USB recovery. That, at least, seems to work for first step : getting U-boot V2 prompt. I can download the enclosed uboot.bin file (binary from http://groups.google.com/group/beagleboard/browse_thread/thread/be194f345b55a887?pli=1, following the link on beagle recovery page). I get u-boot prompt, but can't upload u-boot (V1) via UART as indicated in the tutorial.
First, help command doesn't work. Second, loadb works, with option -f instead of -d. Probably a slightly different version. I then get stuck trying to upload u-boot.bin (V1) via minicom and kermit (installed both gkermit and ckermit). When I lauch the ctrl-A S command, selecting kermit and then file u-boot.bin, there is no activity on the serial line (I have leds on the usb-serial converter) and I have to kill the transfer using ctrl-c. I copied the whole minicom log below.
I suspect my kermit and minicom options are not correct (I am not all that familiar with those tools). Could someone help me with those ?? I suspect one has to set minicom "transfer protocols" option G for minicom, and possibly some modem options too in minicom, and the .kermrc file.
I thank you in advance for your help and concern.

My kermit version is the following :

  Trustees of Columbia University in the City of New York.
Type ? or HELP for help.

USB boot (I have to sudo it for it to work).

Hi,

I'm not really sure I have understood where is your pb :
- you can't boot anything ?
- when you boot the uboot on your SD card that doesn't work ?
- something else ??

For the first pb you can try to boot from the serial port and reflash your NAND from there, you can follow the explanation on :
http://github.com/nmenon/omap-u-boot-utils/tree/master

for the second, are you sure you have built correctly the last uboot version and signed it ?

for the 3rd,sorry If this was useless to you

cheers,

Maxime

or maybe look for prebuilt images here:
http://code.google.com/p/omap-u-boot-utils/
> <mailto:mart...@pfump.org>>
you could try using ucmd, ukermit as in omap-uboot-utils.. also see the
steps which I believe should work in
http://nishanthmenon.blogspot.com/2008/12/towards-creating-beagleboard-nand.html

$1=/dev/ttyS0
pserial -p $1 -f images/u-boot-v2-serial.bin
#OR use pusb for doing downloading u-boot v2 .
ucmd -p $1 -c "loadb -f /dev/ram0" -e "bps..."
ukermit -p $1 -f images/u-boot-v1.bin
ucmd -p $1 -c "go 0x80000000" -e "autoboot"
ucmd -p $1 -c "help" -e "#"

#write u-boot.bin to nand flash:
ucmd -p $1 -c "nandecc sw" -e "#"
ucmd -p $1 -c "nand erase 80000 80000" -e "#"
ucmd -p $1 -c "nand write.i 80000000 80000 80000" -e "#"

#now load up x-loader to write to flash.
ucmd -p $1 -c "loadb 0x80000000" -e "bps..."
ukermit -p $1 -f images/x-load.bin.ift
#flash x-loader.bin.ift
ucmd -p $1 -c "nand unlock" -e "#"
ucmd -p $1 -c "nandecc hw" -e "#"
ucmd -p $1 -c "nand erase 0 80000" -e "#"
ucmd -p $1 -c "nand write.i 80000000 0 80000" -e "#"

once u-boot-v1 changes done are integrated to the mainline, I will try
and create a shell script for running this which could be run at command
prompt.. mebbe koen or someone could help write a recipe for the
individual components sometime?

Nishanth Menon

Hi I had the same problem and fixed it with that script that I
made ::::::

I had to run the script two times ?? I'm checking that right now. I
think that for example if I run it with first partition ended to 50 it
failed and 51 (echo 51 fdisk option ) it passed. I was doing some test
with it and it seem that if I change to 50 try into beagle it failed,
change to 51 try it to beagle it failed and rerun the script with 51,
try it to beagle it works. I think that I have a bad understanding of
fdisk. I mean that if I change the partition size then remount should
I do a sync or something different before remounting... If I found the
problem I will tell you.

I post those details in that post but I don't now why it is not
publish yet?

Hi, in fact, the problem is that I can't transfer files via UART to Beagle using Minicom and Kermit. I need that for USB recovery. Hence I would like someone to give me the correct settings and procedure on Minicom and Kermit (or any other serial tools) to upload binary files to Beagle .

As for my board, it doesn't boot on its own, over NAND or SD, but I can get a limited u-boot V2 (light, and without NAND support) prompt on minicom, with u-boot V2 loaded to SRAM using usb boot. I need minicom and kermit to upload from there the "normal" u-boot.bin (V1) to ram, after running a loadb command on the beagle ... To be able to reformat flash and complete recovery.

I will also try the methods by kpare and maxime louvel, SD or serial boot SHOULD work.
Thank you for your help.

Laurent

A) use ckermit to do it:
from u-boot/tools/scripts/send_image: (modified): copy the following
to a script send_image, chmod +x send_image
#!/usr/bin/kermit +
# usage: send_image FILE_NAME
# e.g. send_image output.bin
set line /dev/ttyS0
set speed 115200
set serial 8N1
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec pack 1000
set send pack 1000
set window 5
set prompt Kermit>
send \%1
out \13
quit
exit 0

open minicom -> run command loadb -f "/dev/ram0"
then press ctrl+a, q to quit without reset.
then:
./send_image u-boot.v1.bin

B) use omap-uboot-utils:

ucmd -p /dev/ttyS0 -c "loadb -f /dev/ram0" -e "bps..."
ukermit p /dev/ttyS0 -f u-boot-v1.bin
it will run loadb command and should download u-boot.v1.bin file.

Thank you very much to maxime louvel, Nisnanth and kapare for the suggestions and scripts. I successfully unbricked my board thanks to your help. I don't know what exactly was wrong with my MMC formatting, possibly just proper syncing and unmounting, but now it works .. and serial transfers also do.
Thanks again

Summarizing the process on a wiki page for others to follow would be greatly appreciated.

Hi Jason,

I can do this and others can verify and validate the doc. Where do you
suggest to do this eLinux or http://code.google.com/p/beagleboard/w/list.
Maybe simply by adding more details in http://elinux.org/BeagleBoardRecovery

Would suggest adding more details to http://elinux.org/BeagleBoardRecovery
since that is people go and will run into the same issues.

I agree this is the best approach. Once things are more stable, then
an entry in the code.google.com site would make sense.
