TI中文支持网AM437x如何通过jtag下载到程序到emmc？

不支持直接通过JTAG加载。
The issue with loading eMMC over JTAG is that before you access the EMMC it needs to be FAT formatted. We don`t have any FAT formatting utilities that run from the target so we rely on host utilities that can format the eMMC over USB so that the ARM can simply use FATFS driver to open/close and write files to the eMMC.If you have some way to format the eMMC before assembling it on your platform. you should be able to test the EMMC over JTAG by simply using eMMC driver and the FATFS driver to create a read write utility.
