Why do i get this error.
Are you sure your hardware is working fine? No RAM problems otherwise?

Dowanload address and load address must differt at by least the size of the uncompressed kernel size.
After reading the manual, REadme and a few posts i came to know that the bootargs were set to NFSboot.
Thisi s not a bootargs issue.
3> I would be able to prepare uRamdisk using mkimage, but that requires an image data file SIMPLE-ramdisk.image.gz to be specified with the -d switch. How do i make the SIMPLE-ramdisk.image.gz so that
Read the manual.
OR from where do i find SIMPLE-ramdisk.image. for ARM processor
For example from our ELDK: /opt/eldk/arm/images/
