Yes. First priority boot source is SDCAR0, before internal NAND.

Then you did not write the SPL loader properly to the SD-CARD I think.

To verify you can find a snapshot build of my version of u-boot  at
http://www.henriknordstrom.net/code/A10/u-boot-mmc-hno-201203.img

just dump it to an SDCARD and it should boot to an u-boot prompt.

For doing anything meaningful you probably want to partition the card
and place system.bin and kernel uImage on it, just remember to start the
first partition at sector 2048 or other sufficiently large number to
leave space for u-boot & environment. The image only contains u-boot and
have no partition table at all. It's verified to boot on my A1000.
