In the boot rom, the eMMC has higher priority if it have firmware.
So what you need to do is override the firmware in eMMC, then you can 
use SD card.
You can do this.
dd if=/dev/zero of=out count=4096

rkdeveloptool db rkxx_loader_vx.xx.bin
rkdeveloptool wl 0x40 out
rkdeveloptool rd

After this, the bootrom should not able to found firmware in eMMC, and 
it will
try to find the firmware in SD card.
