Which version LSDK are you using? How did you generate the boot firmware image?

DDR initialization should be in ATF booting up stage not in u-boot.

You could download LSDK 21.08 pre-built firmware image with the following command.

Then deploy it on the alternate bank of QSPI flash on the target board.

=>sf probe 0:1

=> sf erase 0 +$filesize

=>sf write 0xa0000000 0 $filesize
