PROCESSOR-SDK-AM335X: Cannot start linux from sd card. just waiting...

We have make a new am335x  board, copy most things form starter kit board ,except that we fix the power supply and no need to drive it.   When I try to boot linux from sd card, it shows Waiting for root device PARTUUID=299ac6e7-02...

The mmc in u-boot work normal, but failed in linux.

When I cpoy the evm's MLO, U-BOOT, dtb on this sd card, it can boot linux on starter kit board successfully.

I don't know what is the problem. Can someone help?

My sdk version base on this ti-processor-sdk-linux-rt-am335x-evm-06.03.00.106-Linux-x86-Install.bin

The log is  like this:
