Fw: Montavista Patch for ml403

[Peter Ryser]

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

Further down find the updated instructions. I'll send you the updated 
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 
ML40x and a script to patch a MontaVista Linux kernel from the ML300 LSP 
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 
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 
from MontaVista (http://www.mvista.com). For further information about 
using Linux with EDK, refer to XAPP765: Getting Started with EDK and 
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 
kernel, patches the Linux kernel with necessary changes for the ML40x 
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 
kernel, click Tools->Xygwin shell to run a shell, then type:
$ xmd –tcl genace.tcl –jprog –hw implementation/download.bit –elf <Linux 
elf file> -ace implementation/system.ace
