Beagle board B7 noot booting

Hi All,

I am working on Beagle board B7. I am trying to port Angstrom Linux on my board. But recently my NAND boot loader crashed and now I am trying to boot from SD card. I copied MLO, u-boot.bin, uImage to first partition and Angstrom file system second partition. After copying I connected my board to PC using serial cable and accession through minicom. When I powered up the board it just displaying 40V and followed by some junk characters. Even I hold down USER button for some time but still it is not booting. Can any body suggest how could i solve this problem.

NaveenKumar,

Hi All,

I am working on Beagle board B7. I am trying to port Angstrom Linux on my
board. But recently my NAND boot loader crashed and now I am trying to boot
from SD card. I copied MLO, u-boot.bin, uImage to first partition and
Angstrom file system second partition. After copying I connected my board to
PC using serial cable and accession through minicom. When I powered up the
board it just displaying 40V and followed by some junk characters. Even I
hold down USER button for some time but still it is not booting. Can any
body suggest how could i solve this problem.

I am facing the same problem, no SD access and corrupt NAND.
I am trying to recover from UART or USB as we will not have SD access
until we restore u-boot, i think.

http://elinux.org/BeagleBoardRecovery#UART_recovery
I think we have to load u-boot from SDRAM but i don't know how to do that, yet.

good luck for us,

vjvargas,

thx by your replay.
In this case, NAND is corrupted and we do not have SD card access,
even with User pressed.
It is an unusual situation.

I think we have to recover booting thru UART or USB x-loader and
loading u-boot from SDRAM, am i right ?

Thanks for reply. What ever you suggested that I have already tried. After powered On the board on minicom console it displaying like 40V and some junk characters. I hold down the user button while pressing reset button for 1 min but even there is nothing coming in console means it is not booting. Any other way to solve this issue…

I will also try booting from UART. Please let me know if u solve this problem so that I will follow same.

Hi,

I will also try booting from UART. Please let me know if u solve this
problem so that I will follow same.

I have not solved it yet.
I am a litle bit onfused.

take a look at this page:

that is what i am trying.

#See USB_Boot for a patch to x-loader to boot all the way to Linux via USB.
#You can use USB boot utility together with U-Boot V2 and then use
U-Boot V2's loadb to load U-Boot (V1). Binary: U-boot V2
#Note: USB download can only load programs into OMAP3's internal SRAM.
This is 64k, so too small for U-Boot (V1). But unfortunately, U-Boot
V2 currently lacks NAND support. So we have to use:
# USB download -> U-Boot V2 (SRAM) loadb -> U-Boot (V1) (SDRAM) NAND erase
# For this, get usbload and U-Boot V2 using above links, start usbload
tool at PC and while ... plug in USB OTG (power) cable. At host, this
will result in:

wget http://members.efn.org/~rick/pub/x-loader-usb.tar.bz2
git clone git://git.denx.de/u-boot-v2.git

Hi

Check the power supply ,I had a case of power supply more than 5.1V ,and the pmu wil auto protect

You can try to power with usb otg , Just for verify .

Hope to be helpful

You can try to format with HP format tools version 2.06 , this always work for my board

Hi,

Finally I done booting Linux on my Board. The way I followed is I created one FAT32 partition and made it as bootable. In fdisk tool by pressing ‘a’ we can make the partition as bootable.

download the following list of files adn copy to SD card.

After copying, Insert the SD card, Hold down the USER button then power ON the board. This is the way I followed to bring the board Up. I hope this info useful to you.

I am happy you boot your BB.

Please, could you post your fdisk ?

My fdisk starts at 63, and not 1 and i have tested with boot flag on too:

My NAND is corrupted.

1- How do you fix your NAND ?
2- Have you used fdisk type c W95 FAT32 (LBAc W95 FAT32 (LBA)) ?
3- Does your first partition starts from 1 ?

thx,
