So, the sequence of instructions would be as follows:
1. > Parition the *sd-card* with a 4MB hole:
sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__
2. Format *sd-card *as ext4:
sudo mkfs.ext4 -L rootfs ${DISK}1
3. Copy *MLO* and *u-boot.img* to sd-card:
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/
Question: From where should I execute these commands ?
There is no *u-boot* in */boot* folder on BBB !
