FW: U-boot linux kernel

[srideep.devireddy at wipro.com]

Hi,



  I am right now working on MPC 8272 Ads board  to bring up the u-boot
and the linux kernel on it . As I am success full in bringing up the
u-boot . but I am finding it difficult in getting the linux up . As I
downloaded the vmlinux image from montavista linux site for 8272Ads
board and they  tried to tftp to 100000 at u-boot prompt I am not able
to compress the linus kernel image and go further I end up in getting
the following errors...I tried with two images ... VMLINUX.UBOOT is a
different board image but tried it ... but not able to go further..
later I used the Uimage (got it from vmlinux  using mkimage tool in
linux ) montavista image for mpc8272 ... it ended up giving me the
program check exception ...
