1. Please create two partitions with Linux command "fdisk", one 1G FAT16 and 2G one ext2/ext3 or with remainder of the available disk size.
# mkfs.vfat /dev/sdb1
# mkfs.ext2 /dev/sdb2

2. Please deployed RCW + PBI + BL2(bl2_<boot_mode>.pbl)image to SD card as the following.
dd if=bl2_sd.pbl of=/dev/sdb bs=512 seek=8

note:/dev/sdb is SD device name.

Please deploy TF-A FIP image at 0x00800 in SD card.

dd if=fip_uboot.bin of=/dev/sdb bs=512 seek=0x800

Please deploy FMAN ucode at 0x04800 in SD card.

dd if=fsl_fman_ucode_ls1043_r1.1_106_4_18.bin of=/dev/sdb bs=512 seek=0x4800

you can't find /dev/sdb2

Set the environment in uboot for SD boot.:

setenv bootcmd 'setenv bootargs root=/dev/mmcblk0p2 rw rootdelay=5 console=ttyS0,115200;mmcinfo;ext2load mmc 0:2 0xa0000000 /boot/Image;ext2load mmc 0:2 0xb0000000 /boot/fsl-ls1043a-rdb-sdk.dtb;booti 0xa0000000- 0xb0000000'

saveenv

boot

Moving Image from 0xa0000000 to 0xa0080000, end=a15d6000
