What is the right way to run fw_setenv for selecting different ECC or dtb files?

[Jupiter]

Could anyone please advise how to set up dtb?

In running uuu, I can set up "SDP: write -f imx6ulz-kobs.dtb -addr
0x90000000", but how can I change to different dtb calling fw_setenv?

Thank you and appreciate it.

Kind regards,
