AM5716: AM5716:SDK(9.3) emmc start failed

Part Number: AM5716

Tool/software:

Hi :

   I use the AM571X processor of your company, and the sdk is 9.03. When I use the sd card to boot, it is normal and I can enter the kernel, while when I use the emmc, it has been formatted and well distinguished, but the startup fails. When I enter the uboot, I can either press the command or load it into the kernel and device tree. Any reply and guidance would be greatly appreciated
