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:

ML40x EDK Processor Reference Design

UG082 (v5.0) June 30, 2006

Start XPS and load the Linux XMP:

$ xps system_linux.xmp

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.

Quit XPS.

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 Xilinx XAPP765: Getting

Started with EDK and MontaVista Linux.

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

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
