tl;dr After trying to get my BBB to update or boot from the microSD card, I mistakenly attempted to remove the MLO file from the eMMC partition, thusly bricking my device. I want to attempt to use the exposed eMMC pins in the header to directly write to it and reimage the flash. Possible?
I have been trying for the past couple weeks to get my BBB to boot from the uSD slot, doing a variety of button holds (boot, reset+boot, etc), using a variety of power supplies (initially tried usb, upgraded to beefy 5V10A), and a variety of images (Angstrom, Ubuntu, Debian, both flasher and boot). After unsuccessfully getting it to boot into the uSD card, I attempted one forum post which suggested renaming the MLO so that it would force it to use the uSD. Unfortunately, that has not worked, and now I am left with a brick. Debug serial is a dead line, and it will not boot to anything. Before I give up on it completely, I want to try one more thing: using a second micro, writing a hardware imaging script which will interface to the eMMC directly, reflashing it back to a default state. My questions are this: Will this interfere or cause problems with the processor? Is the eMMC locked by the processor, requiring the use of the password bits to enable write mode? Before I start down this road, what are the means for booting from the serial or USB connections? -James -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
