Tool/software: Linux
Hi,
We have a custom board with AM3358, MMC0 is connect to external SD card, and MMC1 is connect to EMMC. And we are use Processor SDK Linux 04_03_00_05.
Right now i can build a SD card and boot it from it. After boot into linux, I create 2 partition on EMMC, and copy u-boot/MLO/rootfs to these 2 partitions.
After that, i removed SD card, and power on board. It can boot into uboot, but can't enter linux. Here is console output:

Why MMC is not presented? do i need change something in uboot?
