Does the sysutils/u-boot-beaglebone boot the BeagleBone Black for you? As I reported earlier in the start to this thread, I can't get it to boot the system for me. I've copied MLO, u-boot.img, and /boot/ubldr to the FAT partition, but I just get to where U-Boot loads ubldr and then pauses before starting over again in a loop. Are there some other files that need to be copied to the FAT partition, or are those three files, plus the defaults compiled into u-boot.img sufficient to boot the BeagleBone Black from SD card? Cheers, Paul.help
