SK-AM62P-LP: Bad device specification mmc 1

Part Number: SK-AM62P-LP

Tool/software:

SDK v10.1

EVK: SK-AM62P-LP

Command: 

$ cd ${PSDKLA}
$ sudo bin/create-sdcard.sh

Then, the tool re-partitioned SD card, formatted them and copied files into each partition. At this time, we took tisdk-default-image-am62pxx-evm.rootfs.tar.xz as FS.

Switched boot mode to SD Boot, then power on the EVB, then got errors of Bad device specification mmc 1
