U-Boot based on SDK10 

The CN913x u-boot is not public yet, and was taken from Marvell's SDK10

...

Code Block
cp <sdk patch directory>/Base_SDK/base-patches-SDK-10.3.3.0-PR8/uboot/git-uboot-2019.10-SDK-10.3.3.0-PR8/*.patch patches-sdk-u-boot/ $ROOTDIR/patches-sdk-u-boot/The script will apply the u-boot patches onto the mainline u-boot.

If the SDK patches directory doesn't exist, the script will take by default the u-boot.bin provided in the binaries directory.

...

for burning u-boot image only: 

Code Block
sudo dd if=images/flash-image.bin of=/dev/sdX bs=512 seek=4096 status=progress
