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.

   Maybe you did not set your baud rate while config the kernel.     If you use UART16550, you should set your baud rate while config the kernel.In the kernel 2.6.22, the option is in "Platform options", selecting "Default bootloader kernel arguments" and then setting your baud rate. However, if you use UARTLITE, the baud rate dose not need to be set by yourself.   If the problem did not due to the baud rate, then perhaps your xparameters_ml40x.h file did not correctly define the register address of the serial port device. Your can find the correct register address of the serial port device in BSP generated by EDK.                                                                   linyao

Just some random bits I found in the web: http://developer.apple.com/documentation/Hardware/DeviceManagers/pci_srvcs/pci_cards_drivers/PCI_BOOK.250.html The Interesting part is: "Thus, the address swizzle is completely transparent to software." So, I would just try to setup some memory mapping and turn on little endian mode to access that area... MMMV. Just a guess.

From Thomas I got a patched mv643xx_eth driver which is ported to support the 64260, too. Now the driver is integrated and runs complete through initialisation bringing up an eth0 device. The initialisation seams to be ok (no error messages), the device is up and routing information is setup. Now I try to ping a remote station but I receive nothing and I get no feedback from the remote compter. As soon as I turn of the net interface (ifconfig eth0 down) I get the message "Tx time out or no link?) Is there anything else I can check? Any idea what may cause this problem?

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.

Hmmm....  Works fine from my machines.

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

Have you tried the git:// protocol?

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

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.
