TDA4 EVM,boot failed from the SD card

Hi,I'm working with the TDA4 EVM,and want to Run Out of the Box Demos following by:

http://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/psdk_rtos_auto/docs/user_guide/getting_started.html

I have finished the step2.2.1 to step2.2.4,but there are some errors when I run the step 2.2.5.

I insert the SD card,which has been partioned and installed , to the EVM board,then power on,the console port display:

The SD card is 64G,and the BOOT partition is 64M,the rootfs partition is the rest.

How can I run this prebiulted demo?
