You can use 'dd' to extract them from the original drive.. Or the really simple solution, just back them up somewhere on your drive, like i do here: https://www.digikey.com/eewiki/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-BackupBootloader sudo mkdir -p /media/rootfs/opt/backup/uboot/ sudo cp -v ./u-boot/MLO /media/rootfs/opt/backup/uboot/ sudo cp -v ./u-boot/u-boot.img /media/rootfs/opt/backup/uboot/ Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
