Re: Fw: Montavista Patch for ml403

[Peter Ryser <peter.ryser@xilinx.com>]

The linux/patch_linux script has some information on how to apply the=20
patch. For the next release of the reference design we will include more=20
information and also have updated the patch. The new release will be=20
available within the next few days. Check=20
http://www.xilinx.com/products/boards/ml403/reference_designs.htm for=20
availability of the updates.

Further down find the updated instructions. I'll send you the updated=20
patch in a private email.

  Building the Linux BSP (PPC405 Systems Only)

The EDK design comes with MLD/TCL technology to generate a Linux BSP for=20
ML40x and a script to patch a MontaVista Linux kernel from the ML300 LSP=20
for use with this BSP.

To build a BSP for and to patch the Linux kernel, proceed as follows:

1. Start XPS and load the Linux XMP:
$ xps system_linux.xmp

2. Generate the Linux BSP with Tools->Generate Libraries and BSPs

The resulting Linux BSP is located in=20
ppc405_0/libsrc/linux_mvl31_v1_00_a/linux.

3. Quit XPS

4. Create a copy of the MontaVista Linux kernel for the ML300 board.

The Linux kernel and the tools to build the Linux kernel are available=20
from MontaVista (http://www.mvista.com). For further information about=20
using Linux with EDK, refer to XAPP765: Getting Started with EDK and=20
MontaVista Linux (http://www.xilinx.com/bvdocs/appnotes/xapp765.pdf).

5. Patch the Linux kernel for use with the ML40x board
$ cd linux
$ ./patch_linux <path to the copy of the MontaVista Linux kernel>

This step copies the .config file from the linux directory to the Linux=20
kernel, patches the Linux kernel with necessary changes for the ML40x=20
board, and copies the Linux BSP into the Linux kernel.

Build the Linux kernel.
$ cd <path to the copy of the MontaVista Linux kernel>
$ make oldconfig dep bzImage

The resulting Linux kernel resides in arch/ppc/boot/images/zImage.elf

6. To build an ACE file consisting of the FPGA bitstream and the Linux=20
kernel, click Tools->Xygwin shell to run a shell, then type:
$ xmd =96tcl genace.tcl =96jprog =96hw implementation/download.bit =96elf=
 <Linux=20
elf file> -ace implementation/system.ace
