How to change u-boot boot argument and cmdline to mount a partition in my rootfs partition?

I created several partitions, two partitions are formatted by ubifs during u-boot, one is rootfs, a main partition, another is a backup storage, I burned the rootfs partition to the Nand flash, after boot from main partition rootfs, I cannot see the ubifs driver for the backup partition, so I had to run ubi attach and mount the backup storage in rootfs partition everytime in boot, that is definitely a wrong way.


How can I attach ubifs and mount backup storage only once in main rootfs boot up?  I think it should be added to the boot argument, can anyone point me a document how to modify the u-boot boot argument and cmdline?


Thank you.


Kind regards,
