FPGA HW&SW development environment

Software

• Xilinx tools
  • ISE 9.2i -- package for FPGA HW design; compiles input (HDL, netlist, schematics) and optimizes output bitstream according to given user constraints (mainly timing and pin assignment). In our work, ISE programs are almost exclusively invoked by EDK tools.
  • EDK 9.2i -- package for FPGA HW&SW embedded system development; contains libraries of embedded computer IP cores and serves to glue HW FPGA cores together with software.
  • Chipscope 9.1i (optional) -- logic analyzer inside of FPGA. Dedicated IP core sends measured waveforms by JTAG to Chipscope analyzer, running on PC with GUI.
• open-source software
  • libusb-driver -- much better replacement/emulator of driver for Xilinx USB-JTAG adapter
  • gcc 4.3.2, binutils, glibc -- development of system-less as well as Linux SW for PowerPC, contained in Xilinx Virtex-4 hybrid FPGA
  • Linux 2.6.27-rc4 PowerPC kernel containing Xilinx Virtex support

Hardrware

• Xilinx Virtex-4 XC4VFX12 hybrid FPGA IC on ML405 evaluation board

Toolchain preparation and kernel build information

Debian GCC-4.3 build logs

Kernel headers install

http://xilinx.wikidot.com/u-boot

mkdir src
cd src
git clone  git://git.xilinx.com/u-boot-xlnx.git
git clone  git://git.xilinx.com/gen-mhs-devtree.git
git clone --reference /usr/src/linux-devel git://git.xilinx.com/linux-2.6-xlnx.git

mkdir -p build/ml403/linux
cd build/ml403/linux

Copy and adapt GNUmakefile to override ARCH and select kernel source directory

Run

make headers_install

The header-files for building GCC nd GLIB are prepared in usr/include directory. Copy files found there to the directory /usr/powerpc-linux-gnu/sys-include

Glibc

The required files are glibc-2.7ds1.tar.bz2 glibc-linuxthreads-20071023.tar.bz2 glibc-libidn-2.7.tar.bz2 glibc-ports-2.7.tar.bz2

mkdir -p src
cd src
tar -xjf ../glibc-2.7ds1.tar.bz2
tar -xjf ../glibc-linuxthreads-20071023.tar.bz2
tar -xjf ../glibc-libidn-2.7.tar.bz2
( cd glibc-2.7 ; mv glibc-libidn-2.7 libidn )
tar -xjf ../glibc-ports-2.7.tar.bz2
( cd glibc-2.7 ; mv glibc-ports-2.7 ports )
ln -s glibc-2.7 glibc

Prepare directory to build PowerPC version of GLIBC

mkdir -p build/powerpc-linux/glibc

If there is no previous install of GLIBC, use next dummy build to install headers. They are required to build GCC later
