BeagleBone Black bricked

GoogleGroups
1

I have somewhat bricked the BeagleBone Black. When I boot it, when connected using the serial port, it does write the ‘C’ character continuously. Looking through the board I have seen the a post (https://groups.google.com/forum/#!topic/beagleboard/pDr_rLDYqy4) where it has a similar problem. I have tried reflashing the eMMC using several images but no luck at the moment.

Using the flasher images, this is the output using the serial port:

Looks like the flasher in the uSD isn’t able even to boot. Is there any way to solve this problem ?

Thank you,

Best regards,

I’d recommend to get a Linux-distro that runs from microSD card too (like Ubuntu), boot it with Boot-switch pressed and then check the eMMC manually/copy the distro to it.

I have fixed it now.

This was my scenario. I have two BBB boards, running the same OS image, and a uSD card with that same OS image. All runned fined, until I did something wrong with one of them and it bricked. It wasn’t able to boot from either the eMMC nor the uSD, the other BBB board booted though.

The bricked BBB wasn’t able to even boot, uboot wasn’t loaded, by writing the ‘C’ character continuously. With the flasher image loaded in another uSD it booted, but the kernel was crashing.

So, finally, I booted the bricked BBB with the flasher image uSD until it displayed ‘Hit any key to stop autoboot’, the I swapped the flasher image uSD with my OS image uSD, and it finally booted it. Then I reflashed it and the BBB came back to life.

So I guess that uboot was broken in the bricked BBB.

Anyway, thank you,

Best regards,

I have been looking at the booting process in the past, but I don’t have enough knowledge about U-Boot. Anyway, in case it’s any helpful for you, take a look at this link:
