Here are my instructions how to solve boot issue on eMMC (see one warning which I get below):
All commands should be run on BBB as root or add sudo. Checkout and patch u-boot as described here: https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-Bootloader:U-Boot Do not build yet. ``` nano configs/am335x_boneblack_defconfig ``` Add these lines to the end of the file: ``` CONFIG_AUTOBOOT_KEYED=y CONFIG_AUTOBOOT_PROMPT="Autobooting in %d seconds, enter \"stop\" to stop\n" CONFIG_AUTOBOOT_STOP_STR="stop" CONFIG_AUTOBOOT_DELAY_STR="delay" ``` Then compile u-boot running these commands: ``` make ARCH=arm CROSS_COMPILE=${CC} distclean make ARCH=arm CROSS_COMPILE=${CC} am335x_boneblack_defconfig make ARCH=arm CROSS_COMPILE=${CC} ``` Now you should have u-boot.img and MLO files compiled. Write them to eMMC boot calling these commands: ``` dd if=MLO of=/dev/mmcblk0 count=1 seek=1 conv=notrunc bs=128k dd if=u-boot.img of=/dev/mmcblk0 count=2 seek=1 conv=notrunc bs=384k ``` Done. Try to restart. If you have serial connection, check if you will see message when BBB starts "Autobooting in 1 seconds, enter "stop" to stop" Warning: After applying this I see warning when u-boot starts "*** Warning - bad CRC, using default environment". By this warning description here (http://www.denx.de/wiki/view/DULG/WarningBadCRCUsingDefaultEnvironment) seems like it's not critical or even important, but still, maybe someone has an idea how to solve it?
