now we have successfully converted the HS-FS device to HS-SE, and while trying to boot the device by SPL mode.

We would like to know how to modify the configuration of uboot or linux to use our own key instead of custMpk.pem provided by TI to implement the signature

    Hi hongyao.jin,

    While generating the signed tispl,tiboot3.bin,uboot.img image build infra make use of k3-j784s4-binman.dtsi configuration file . In default SDK the root trust keys used to sign the image is custMpk.pem, which is TI dummy key you need to use you key instead of TI dummy key.

    For the kernel  fitimage generation follow the SDK docuemanataion.
