Hi All, I am trying to boot Linux from uboot. I have cross compiled Linux and ramdisk for my board. After cross compilation i did a tftp to download the image(Linux + Filesystem) to RAM(0x80800000) . From there i copied it to flash(0xad040000).
Now on a reset u boot comes up and then when trying to bring LINUX it throws an error saying Verifying Checksum.......Bad data CRC. Then uboot prompt appears. This is what happened.....
