imx8mn boot from boot0 and write to boot1.

Hi

I am using an imx 8m nano evk. I need to have the bootloader in the boot partitions of emmc. Initially it should boot from boot0 (boot partition 1) and write to boot1 (boot partition 2).The next time it should boot from boot1 and update to boot0. How can I handle this in the uuu script?

Really appreciate any help.

Thanks !

The uuu can't support such function, this needs you change the uboot source code and uuu code.We don't have such solution at present.

Thanks for your reply!

I think, I managed to write to both boot partitions. Now I need to set an environment variable and save it. But the saveenv doesn't work from uuu script.
