linux on virtex 2 pro board

Started by rajendra k singh ●August 17, 2004
Hi All,
    I am trying to boot linux on virtex 2 pro P7-ff672 board. My problem is
that I am able to boot the linux image(ppc) on bitstream generated by EDK
6.1 but not with bitstream generated by EDK 6.2 (SP2). Does anyone had
similar experience ? I wonder if the problem is EDK 6.2 or I need to change
my  liuux image which should not be the case as I am using the same version
of cores. Following is the only message I get on bitstream generated by 6.2
EDK.

loaded at:     00400000 0045D1E4
board data at: 0045A13C 0045A154
relocated to:  00405600 00405618
zimage at:     00405AFB 00459C4F
avail ram:     0045E000 02000000

Linux/PPC load: root=/dev/nfs rw ip=on
Uncompressing Linux...done.
Now booting the kernel


While the same Image produce following message on 6.1 bitstream

Raj,

just looking at the kernel command line I would say that these are two 
different Linux kernels. In one case you try to boot from NFS in the 
other from a RAM disk.

ok, my mistake. I didnt tell that I had two linux image just to avoid any
confusion. But I tried both the images (one with root=/dev/nfs and other
with root=/dev/ram) and both hangs after "Now booting the kernel message".
