[beagleboard] Is my BB Bricked?

Neil · April 28, 2010, 4:55pm

Hello,

I have a beagleboard which has the follwoign symptons:

Cannot boot from my SD card
The power light comes on but the USR lights do not
Nothing comes down the RS232 connection

Is there anything I can do to evaluate what is going wrong with the device or am I out of options (short of buying a debug board).

Cheers,

Neil

Hi Neil!

BB boots from SD card. Necessary files MLO and u-boot are on a SD card. If these files are not loaded then USR led can’t be lid and, obviously, rs232 connection must be dead also.

What is wrong with your SD card? Can yiu open it on a usual PC to watch it’s content?

regards,
Max

Hello,

SD card runs fine - this actually happens when there is no card in (or with the card in). My other board (I have two BBs) with no card shows the x-loader down the serial line when it starts with no card in so that is the strange thing - it is like there is no x-loader. I’ve followed the recovery instructions to try to flash a new x-loader on but nothing; it just sits there. On my other board when the OS does not load from the SD card the USR light is not out but solid and then flashes when the u-boot is loaded from the SD card.

Thanks for your reply - do these symptons sound familiar?

Cheers,

Neil

Hi,
My beagleboard (Rev C) is continuously displaying this message on serial console and I tried beagleboard recovery techniques with serial/USB. Nothing works. Can anyone help me in recovering this board.

Hari

Check the power supply to the board. I've seen them do that when not
given adequate power.

You have a power supply issue.

Thanks for the suggestion. It is booting when I connect both 5V external supply and USB. However serial console input is not accepting.
Any suggestions?

That could be a cable issue. I have seen that happen when the ribbon cable is the wrong type. There are two different types if ribbon cables. One works and the other one does not. Go through the System Reference Manual and go to the section where you verify the pinout of the cable.

I've had a similar problem, I'd get stuff printed to the terminal just
fine but keystrokes seemed to be not being sent. If you're using
PuTTY try using a different method for serial communication. I
switched from PuTTY(on windows) to screen (Linux) and all my problems
with this stopped, not sure if the problem was with PuTTY or Windows
but this worked for me. Here's some info on screen

It appears that my NAND flash is erased. I tried board recovery with UART recovery method and I get the prompt.
But the bin that I used does not have (from the beagleboard recovery page UART method) does not have nand unlock etc…
I need to write into NAND flash. Can anyone help me in suggesting how to flash the NAND. And the right u-boot, x-loader etc… to download.

Hari
