Help with BSE-IP Board and Linux 2.2.5

Help with BSE-IP Board and Linux 2.2.5

[Grant Carter]

Hi all

Perhaps someone can help me. I have just received my BSE IP-Engine and
have compiled the 2.2.5 kernel for it. The compilation went successfully
and, after setting up the IP address etc on the board and getting my
TFTP server running, I downloaded the kernel to the board (via Ethernet
so I know it is working). Since the user space starts at 0x4000, I
loaded the zImage there. When I tried to run it, the BSE board froze. I
found that I had downloaded an old kernel from linuxppc.cs.nmt.edu for
the BSE board and when I tried it, I got the same results. Does it
matter to the kernel at what address in memory it is loaded and if so,
where can I change this is the linker?

I have set up my NFS server with the mbxroot.min files in it. I am not
100% sure that this is working but am I correct in assuming that I
should see the beginning of the kernel booting before it requires any
files from the NFS server? 

Any ideas on how to proceed from here? Does somebody have a known
working kernel for this board which I can try?

TIA
Grant

So, I guess it doesn't matter that I write the help file :-)?

If you look at 'embedded_notes' it tells you to load the image
at 0x200000.  The code on the front of the zImage file will uncompress
and load the kernel starting at memory address 0.  You have to allow
a few hundred Kbytes for this to happen, and allocate some working
space for the kernel.

In fact, the explicit commands for the BSE-IP are there......

The image doesn't really care where it is loaded, so long as it is
above about 1.5 Mbytes or so.......
