thanks scott.
i loaded my u-boot image to nand flash its fine. and also I need my kernel image and rootfs also in nand flash so that my system should make kernel UP using nand flash. how can i do this using nand flash as we are using only nand flash as boot device.

hello, I was able to solve nand erase and nand write and saveenv. Now,I am making kernel up and followed below steps..
tf 1000000 uImage_icm_v1.1 nand erase 0x00200000 361483 nand write 1000000 0x00200000 361483
tf c00000 p1021rdb_32b.dtb nand erase 0x00100000 3000 nand write c00000 0x00100000 3000
tf 2000000 mini.rootfs.ext2.gz.uboot nand erase 0x00600000 2115d4 nand write 2000000 0x00600000 2115d4
then to boot kernel from nand i used bootm 0x00200000 0x00600000 0x00100000
Bootm takes a RAM address, not a NAND address. Unlike NOR flash, NAND is not directly addressable. You need to use "nand read" first.
