ML403 patch for UBOOT

ML403 patch for UBOOT

[alayrac]

I'm new member of this mailing list an I'm looking for some information
on UBOOT on ML403.

stevea-mdi talk about a pacth from  Ameet
(http://www.linux2knowmore.com) but I did not succeed to find this
pacth.
The one attached to the mail
(http://patchwork.ozlabs.org/linuxppc/patch?id=6502)  seems to be for
linux 2.6.17-4 and not for UBOOT.

Is there something I'm doing wrong?

Where can I found a pacth for UBOOT for ML403?

Thank you in advance for any help

Chris

Thank you Ming for your prompt reply. It is exactly the pacth I've found
previously.
The pacth start with the following lines :
diff -Naur linux-2.6.17-4.patch1/arch/ppc/platforms/4xx/xilinx_ml300.h
linux-2.6.17-4.working/arch/ppc/platforms/4xx/xilinx_ml300.h
--- linux-2.6.17-4.patch1/arch/ppc/platforms/4xx/xilinx_ml300.h 2006-07-25 16:42:50.000000000 -0400
+++ linux-2.6.17-4.working/arch/ppc/platforms/4xx/xilinx_ml300.h        2006-08-02 19:47:00.000000000 -0400

I understand from that that it try to change linux-2.6.17-4 xilinx_ml300.h
If I type from u-boot (1.1.4) source code directory
patch -i U-BOOT 
with U-BOOT the text file containing that pacth then it stop askink for file path.

So I wonder if the pacth is for UBOOT or Linux 2.6.17-4 kernel source?

I should precise that I'm a beginner with Uboot and linux 2.6 (already port linux 2.4 on ML403 using BYU instructions)
I must miss something basic...

Thanks for your help

Chris,

You are correct, that patch is for the Linux kernel and should be 
applied to the kernel if you are planning on using u-boot.  It ensures 
that the board_info structure in the kernel matches the one used by u-boot.

Xilinx has a u-boot tree that works with the ML403 board.  It is 
available here:
http://www.xilinx.com/ml410-p/designs/u-boot.zip

Good luck,
Frank

No problem. I am also a beginner. :)

You might want to start with XAPP542
http://direct.xilinx.com/bvdocs/appnotes/xapp542.pdf
http://direct.xilinx.com/bvdocs/appnotes/xapp542.zip

The zip file includes the U-Boot patch for Linux kernel 2.4.

Re: ML403 patch for UBOOT

Hi Ameet,

Thanks for your reply
> you got the URL wrong. Its http://linux.get2knowmore.com
I've got the right address but I've made an error in the email.

Following your instrcutions I've succeed to run the 2.6.17.1 kernel on
my ML403 board. The process stop when I try to mount the NFS root file
system. This is because there is no Etehrnet drivers.

It seems that Xilinx will release SP2 for EDK 8.2 very soon and that
issue should be solved.

We decide to work on u-boot on that ML403 board (and linux 2.4.26 very
well documented on byu web site, link on your web page) . To do so I use
ML403 ppc ref design and I've dowloaded the u-boot.zip from xilinx
website.

This u-boot.zip have empty files for sw_services (tcl script...), and
I've noticed that memory map found in u-boot/board/ml403/xparameters.h
did not match the one of the design from Xilinx.

I've then modify the address in this file and I succesfully start U-boot
on that board.

Unfortunately, the process stop on the last line of do_boot_linux when
whe are supposed to get back to entry point at address 0x00000000.
(the uImage is properly unzip, and CRC OK).

I did not know why the process stop?
Do you think it has something to do with the hardware design?
Should I modify the mapping of the hardware to macth the original memory
map of the xparameters.h that comes with this u-boot.zip file?
(that is the next track I'm working on).

I did not found PartII on your web site, it is an error from me or you
did not find time to publish it?

Thanks any way for your contribution and your help.

Kinds Regards

Chris
