I could change the path form MMC to NAND when save the u-boot variable for help.
Re: how to change the u-boot environment to NAND when saveenv on i.MX28 coustom board
And I add NAND parameters to u-boot source code so I got the below result as log.

Hit any key to stop autoboot: 0
But I can't save the variable when saveenv. The log is
MX28 U-Boot > saveenv
Saving Environment to NAND...
Erasing Nand...
Erasing at 0x140000000020000 -- 0% complete.
Writing to Nand... done
MX28 U-Boot >
I don't understand the eraseing address. (0x140000000020000)
When do saveenv command the function saveenv in u-boot/common/env_nand.c calls nand_erase_opts function in u-boot/drivers/mtd/nand/nand_util.c
I did the check the address erase.addr value in nand_erase_opts function.
The address erase.addr value is diffeent when call it.
Can help me?
