Hi Gary,

Are you asking Ethernet boot in Linux or RTOS?

In Linux, U-Boot doesn't support Ethernet boot yet.

CPSW Ethernet boot is documented here: https://software-dl.ti.com/processor-sdk-linux/esd/AM64X/08_05_00_21/exports/docs/linux/Foundational_Components/U-Boot/UG-Network-K3.html

Note that as highlighted in the documentation on SK-AM64 it is important to set the BOOTMODE[7] pin (Link info) to '1' to get the device to send out DHCP requests and start the boot process. Below photo shows a working CPSW Ethernet Boot configuration (with UART as a backup boot mode) on SK-AM64B.
