BSP 3.04 - Update device tree

With BSP 2.8 i could do the following to update the device tree on the device

‘pause UBoot’

run setupdate
run prepare_ubi
run update_fdt

This does not seem to work. This is what i get ( Note : I have network connection and SD with easier installer on it)

Device tree binary located at UBI partition “dtb”. You can update it directly from Linux using

 ubiupdatevol /dev/ubi0_1 <dtb_binary_file>

Or you can do it from U_boot: - Load dtb binary from SD to RAM, then

# ubi part ubi  
# ubi write <addr_in_RAM> dtb <size in bytes>
