My thunderboard is dead. Please help me

[Errol Blanco Valverde]

Hi everybody!!

Im new in the group, and I arrived here because I have I BIG BIG
problem. When the pack arrives it becomes preloaded, so I check that
everything works fine. But when I tried to load it, simply crash it.
----------------------------------------
Here's what I did:
1. I download the tao-20100806.tar.bz2 and I place it in /root/
tao-3530
2. So I tried to make the bootable SD Card. At this point, I don't
knew that this script only works fine when the OS is english, and have
it in spanish (Ubuntu 10.04). Im new in ubuntu, so I didn't realize
that I have problems with the script.
3. Then I connect the board to the PC, I stop the boot, just like said
in the documentation. All was fine at this point, I could see the
board booting in the terminal. The problem begans when a write "nand
erase clean" in the terminal, it erase all fine, but I forgot to put
the SD Card in the slot. (by the way, the sd card wasn't made properly
because the language; now I fixed it. I just check the script and saw
that the script does a "GREP Disk", but like a have my OS in spanish,
it must said "GREP Disco", simple, but it didn't make the partition
properly, so the script can't copy the boot and the rootfs in the sd
card).
4. Since that I can't do anything with my board. The LCD still white,
don't show anything in minicom or GtkTerm, nothing... I have 3 leds
on: First on the tao, beside the wifi module. Next one is between the
screw and a 6R8 IC and the final one is always flashing, and it's next
to the battery interface that closer to this 6R8 IC
-----------------------------------------------
Im tried this:
1. Change the Null modem cable
2. Use a usb - rs232 cable
3. I change my OS language to english, and the script works fine (0
errors)
4. I did a bootable sd card by myself. I did 2 partitions with
gparted: the first one with fat 16(64MB) and the last one with
ext3(around 930MB); then I did this

cp /root/tao-3530/tao-20100806/boot /media/boot

cp /root/tao-3530/tao-20100806/rootfs /media/rootfs

cp binaries/thunder/uImage /media/boot/
rm -rf /media/rootfs/lib/modules/*
cp -rfa binaries/thunder/lib /media/rootfs/

5. I used this tools develop in http://code.google.com/p/omap-u-boot-utils/
to try the copy the uboot on the nand. I tried this

root#./pserial -p /dev/ttyS0 -f /root/tao-3530/tao-20100806/prebuild/u-
boot.bin
Waiting For Device ASIC ID: Press Ctrl+C to stop ////// that's all,
it didn't do anything

I tried this other
root#./pusb -f /root/tao-3530/tao-20100806/prebuild/u-boot.bin
Waiting for USB device vendorID=0x451and productID=0xD009:
Dev #6: Texas Instruments - OMAP3430
File:System Error: : No such file or directory
Could not stat /root/tao-3530/tao-20100806/prebuild/u-boot.bin
send_file:293:Filesize -1 >65536 max
main:541:send file failed

I know that maybe the problem with the last command is that the tool
has this productID=0xD009, I don't if that is fine to thunderboard,
probably not. But I found something rare when executed this

root#dmesg
....
[ 6611.089998] usb 1-7: USB disconnect, address 7
[ 6614.612024] usb 1-7: new high speed USB device using ehci_hcd and
address 8
[ 6614.746387] usb 1-7: configuration #1 chosen from 1 choice
[ 6615.046533] usb 1-7: USB disconnect, address 8

Looks like, the board isnt recognize by the pc. When i executed
"lsusb" don't show the board
----------------------------------------------------------
Things that I will do soon:
1. Right now, I'm downloading Visual Studio 2005, winCE 6.0, and all
the upgrades to try since Windows Xp
2. Cry

Please help me, i need restore my thunderboard to continue to my
project

Hi

I already fixed. Looks like I has two problems: first one was the
language ( like I said before); the second one was a bad contact in
the rs232 cable that came with the board. It's rare because I tested
it with a multimeter, and looks fine; but when I was trying
everything, i built my own cable, and it's works! Now this cable is my
best friend :-)
