[U-Boot] problem while making kernel up

[Manukumar]

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

it is giving below log message.
	
	
 2168276 bytes written: OK
=> bootm 0x00200000 0x00600000 0x00100000
WARNING: adjusting available memory to 30000000
Wrong Image Format for bootm command
ERROR: can't get kernel image!


and also my next question is 
cp.b 1000000 0x00200000 100000 not working it is showing log as:

=> cp.b 1000000 0x00200000 100000
Copy to Flash... Flash not Erased

why this is happenning please give me the solution for this.
