hello, I was able to solve nand erase and nand write and saveenv. Now,I am making kernel up and followed below steps..

1. tf 1000000 uImage_icm_v1.1 nand erase 0x00200000 361483 nand write 1000000 0x00200000 361483

2. tf c00000 p1021rdb_32b.dtb nand erase 0x00100000 3000 nand write c00000 0x00100000 3000

3. 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.
