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,

Hi,
To flash u-boot to iMX6ULL NAND, it requires using higher bits ECC (my imx6ulz_kobs.dtb) to run kobs-ng in ramdisk, but to flash rootfs image to NAND in ramdisk, I have to change to use lower ECC (my imx6ulz.dtb).
I followed the advice at link https://developer.toradex.com/knowledge-base/u-boot-fw-utils to run "fw_setenv fdt_file imx6ulz_kobs.dtb" before flashing u-boot to NAND, although the fw_setenv command worked, the u-boot wasn't installed properly in NAND, I could not boot from NAND.
What is the right way to run fw_setenv for changing different ECC or different dtb files?
Thank you.
