    Thanks for the reply.

    Should the commands be run in the UART terminal window?

    Hello,

    The k3conf commands suggested by Kyle are Linux based commands.

    You cannot run these from "u-boot", which is the way you are attempting now.

    Please boot to Linux and run these commands.

    Regards
