We changed uBoot to boot from SD card something like this:


We boot Freescale target via NFS or TFTP:

On the target, SCP from the host to the target:

Run: scp <SSH_SERVER_NAME>@<IPADDRESS>:<SUBDIR of uImage>/uImage . (. Is current directory on the target. Must be R/W.)

Run: cat uImage > /dev/sda1


You need a partition (mount point) for each of uboot, uboot-env, uimage, dtb, filesystem.

When you copied all to SD card, reboot and stop uboot.

Change the uboot env to boot from SD card.
