1. What you get after the build ?
You get a mini Linux Distribution adapted for the UNISIM Virtex 5 FXT Simulator. The distribution is based on Busybox and the MiBench version 1 benchmark suite. At least four files are needed to boot Linux in the simulator:- A boot program (PPC440 startup):
boot.elf
- A Linux kernel:
vmlinux
- A device tree (a machine description for Linux):
device-tree-16m.dtb
device-tree-32m.dtb
device-tree-64m.dtb - An initial RAM disk image (a root file system):
initrd.img
initrd_automotive_basicmath_large.img
initrd_automotive_basicmath_small.img
initrd_automotive_bitcount_large.img
initrd_automotive_bitcount_small.img
initrd_automotive_qsort_large.img

2. Requirements
- A Linux host machine with the sudo rights
- A GNU cross tool-chain: follow the instructions here
- Binaries and data sets of the MiBench version 1 benchmark suite: download
- make 3.82 (may not work with make 3.81)
3. Get the material
Download that tarball. It contains all the necessary material (scripts and source codes) to get a mini Linux distro for the UNISIM Virtex 5 FXT Simulator.4. Uncompress the tarball
$ tar zxvf
unisim-virtex5fxt-linux-distro-source-v4.tar.gz
5. Build the Linux distribution
Run the building script:$ cd
unisim-virtex5fxt-linux-distro-source-v4
$ ./build.sh all ${HOME}/mibench-v1-bin-powerpc-7450-linux-gnu-v4 ${HOME}/crosstool-source-v3/powerpc-440fp-linux-gnu
$ ./build.sh all ${HOME}/mibench-v1-bin-powerpc-7450-linux-gnu-v4 ${HOME}/crosstool-source-v3/powerpc-440fp-linux-gnu
Adjust the arguments of the building script to your cross tool-chain and MiBench installations. Be patient...the process of building the Linux distribution is quite long.
6. Check your distro build/simulator build (optional regression test)
Run the checking script:$ cd
unisim-virtex5fxt-linux-distro-source-v4
$ ./check.sh ${HOME}/unisim-virtex5fxt-1.0beta11/virtex5fxt/bin/unisim-virtex5fxt-wfpu-1.0beta11 1234
$ ./check.sh ${HOME}/unisim-virtex5fxt-1.0beta11/virtex5fxt/bin/unisim-virtex5fxt-wfpu-1.0beta11 1234
