Hello,
I am using xilinx ml310 board. Now I want to use networking feature on
the
board
and hence I have to enable the "ENABLE PCI" option in the
configuration of
kernel which I am trying to load onto the ppc.
Now once I enable the enable pci option what happens is that the kernel
during
the make zImage command execution asks for the following parameters
which are
not present in the xparameters_ml300.h file

`XPAR_PCI_0_IO_BASEADDR'
`XPAR_PCI_0_CONFIG_ADDR'
`XPAR_PCI_0_LCONFIG_ADDR'

All these parameters I believe get added in xparamters_ml300.h file. If
I am
using ml300 board and I add the pci module in the bsp then they get
added.
However the ml310 board has a different architecture and hence the pci
bridge
parameters get added instead of the above.
How do I get around this problem.If I disable the pci then I can
compile the
kernel succesfully. But to use the networking feature I believe I have
to use
pci.
Has anyone come across this problem?
Has anyone successfully compiled linux kernel with pci support on
ml310?
Thanks,
Nitesh

Please visit the ML310 web pages at
http://www.xilinx.com/ml310. Under 
Documentation and reference designs you will find a section of 
information on how to build a Linux system including PCI. One of these 
documents is a "Tutorial on how to configure and re-create the Linux 
kernel for the PCI design using XPS and MVL 3.1 Pro."

Cheers,

Which kernel are u using...I have been trying to
get a custom kernel on
the ml-310 since many months and still I am not successful...Anyways I
ported 2.4 and 2.6 without PCI support , but with PCI, I could compile
the kernel but I couldnt get it to boot...

I recommend to start with the MontaVista Linux
Preview Kit for the 
ML300. It can be downloaded from http://www.mvista.com/previewkit free 
of charge. The web pages I pointed you to are based on the MontaVista 
Linux 3.1 Pro edition. The previewkit is the same as far as the kernel 
goes but does not have the advanced development tools (Eclipse, etc).

Hello,
I am able to compile the kernel succesfully.
Now I have one more problem. I load the bit file and download the
kernel.
The following screen appears on my minicom and then goes dead.
Enter Desired System ACE CF Configuration <0-7>.
   0: ACE-loader.
   1: Linux w/PCI.
   2: VxWorks w/PCI.
   3: QNX Demo.
   4: Linux EDK Base Build.
   5: VxWorks EDK Base Build.
   6: User Configuration A.
   7: User Configuration B.


Select:

Linux/PPC load: console=ttyS0,9600 root=/dev/xsysace/disc0/part2 rw
Uncompressing Linux...done.
Now booting the kernel




It gets stuck on booting the kernel. 
Any suggestions....
Thanks

Hi Parag ,
I am using 2.4.26 kernel.
I am also trying it with the monta vista preview kit as told by peter.
I will try the pci example  with the montavista kernel.
For the pci parameters eroor what I did was I copied the parameters
from the xparameters_ml300.h file patch given by Andrei Konovalov on
http://galileo.gamepoint.com.au/pub/linux/kernel/people/akpm/patches/2.6/2.6.9-rc4/2.6.9-r
c4-mm1/broken-out/ppc32-xilinx-ml300-board-support.patch
