The file sd_pt_4k.img is 4K content placeholder, it is provided by LSDK team, suitable for all SD cards, no need to modify it, please download it from the following link to use it directly.

The file firmware_ls1046ardb_sdboot.img is built in LSDK 21.08 with the following command.

$ flex-builder -i mkfw -m ls1046ardb -b sd

If you are bringing up your custom board based on ls1046ardb, you need to customize ATF source code according to your custom board, especially the DDR initialization section.

For your error log, it seems that there is SD card reading problem, please try to use other SD card to do more verification.
