For the DM816x, C6A816x and AM389x, there are instructions on how to boot the kernel over TFTP and mount the filesystem via NFS at the following location. This is a copy of the Platform Support Package (PSP) User's Guide.

thanks!

i know little about linux booting.

according to "Boot over Network (Ethernet)", there are two files "uImage" & "ramdisk.gz", where to find "ramdisk.gz" or how to make it ?

it seems that "ramdisk.gz" is only required in boot over TFTP, not required in boot over NFS.

That section gave 2 different examples of a filesystem. One, the ramdisk.gz, is RAM Disk filesystem. The entire linux filesystem is compressed into a RAM disk and then loaded into DRAM.

The other example is a NFS mountable filesystem which is generally preferred for development purposes.
