Problems on porting linux 2.6 to xilinx ML410

Hey:
    Recently I'm doing some project on Xilinx Ml410 evaluation board.The first step is porting linux 2.6 to ml410,but I got some problems on this,and my project cann't proceed,so I come to you for some help.
    I use the linux kernel source tree download from  http://git.secretlab.ca/git/linux-2.6-virtex.git  (The latest one).Add the file the xparameters.h,xparameter_ml40x.h.  Then add arch/ppc/platforms/4xx/xilinx_generic_ppc.c(Use the patch I get here),and change it's name to ml40x.c,then I make some necessay change of the configuration files to accept selecting a Ml40x type board.Then compile the kernel,and get the image file from arch/ppc/boot/images, (On kernel compiling,the only device driver  I sellect is " 8250/16550 and compatible serial support ").After that  I download the zImage.elf file to the target board,and run it.But there is no output from the serial port at all.Am I doing somthing wrong?I really don't know goes wrong.
    Can anyone here help me with this?Any help from you is appreciated.Thank you very much!

        


                                                                                                                                                                                    woyuzhilei

You shouldn't need to do all of this; only the xparameters_ml40x.h
file is needed.  To get started, I'd just use replace
xparameters_ml403.h with your custom xparameters_ml40x.h and use the
ml403 board port.  Once you've got it booting, you can get more fancy.

Make sure you've got 16550 console support enabled and
'console=/dev/ttyS0' in your kernel command line.

how to get your linux-2.6-virtex tree?

[Ming Liu]

Dear Grant,
I am trying to get your linux-2.6-virtex tree. When I release the command 
"git-clone git://git.secretlab.ca/git/linux-2.6-virtex.git", it shows 

fatal: unexpected EOF
fetch-pack from 'git://git.secretlab.ca/git/linux-2.6-virtex.git' failed.

How can I get your tree? Thanks for your telling.

BR
Ming

Hmmm....  Works fine from my machines.

What does 'dig git.secretlab.ca' tell you?  I see this:
;; ANSWER SECTION:
git.secretlab.ca.       1320    IN      A       208.123.74.12

Have you tried the git:// protocol?

This is what I get when I clone from another machine:

grant@trillian:~/temp$ git-clone

I just checked it for you, both http and git are working.

I released 'dig git.secretlab.ca' and saw this: 
;; QUESTION SECTION:
;git.secretlab.ca.              IN      A

;; ANSWER SECTION:

Yes. I tried both git:// and http://. 

For git:// protocal:
mingliu@romeo ~ $ git-clone git://git.secretlab.ca/git/linux-2.6-virtex.git
fatal: unexpected EOF
fetch-pack from 'git://git.secretlab.ca/git/linux-2.6-virtex.git' failed.


For http:// protocal:

Upgrade to a newer version of git.  git.secretlab.ca uses the virtual
hosting feature of git daemon, but you need to be using git version >
1.5

Re: how to get your linux-2.6-virtex tree?

[Ming Liu]

Dear Grant,
That's right!!! My git's version is quite old. OK then. Thus I will upgrade 
my git and obtain your kernel tree. Thanks for your help.
