Is uImage built is wrong or it is due to ramdisk file has some problem?...
plz provide me d solution for dis..?

Seema

Load the image to a different address and run from there. The image is a compressed one and it unpacks itself to 0x20080000, thus overwriting the source image (see load address, this is inserted into the image while generating it). You must have non-overlapping areas for source and destination of decompression.
