unble to mount rootfilesystem from cramfs

[Sreekanth Rupavatharam]

Hello,

I am unble to mount rootfilesystem from cramfs...
Any suggestions on where I am going wrong?.
------steps i am following-----------------
1.In physmap, added 2 partitions: 0 for kernel, 1 for cramfs rootfilesystem.
2.make menuconfig: select cramfs, set root=/dev/mtd1.
3.make zImage.initrd,
4.create binary
5.objcopy -I binary -O srec --set-start=FLASH_BASE_ADDR kImgName
6.Using BDM flash the srec file to FLASH_BASE_ADDR
7.mkcramfs -r b filesystem fileImageName
9.objcopy -I binary -O srec --set-start=RFS_ADDR fImageName.bin fImgName.s19
-Here the RFS_ADDR corresponds to the mtd1 'offset'.
10. Using BDM flash the srec file to RFS_ADDR
