I think you do not have CONFIG_SPL_FAT_SUPPORT or CONFIG_SPL_EXT_SUPPORT
defined in the board config file and SPL uses MMCSD_MODE_RAW and just
reads at offset CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR of the card
and not from the partition 3.

SPL reads at byte offset 0x140000 of the device it seems.

Does SPL detect the image if you write it to the sd-card as below?

  dd if=u-boot-with-spl.sfp of=/dev/sdb bs=1M seek=1

But please only write it this way if there is no partition
with important data at the beginning of your sd-card.
