Introduction
MicroController Linux (μCLinux) is a Linux operating system for embedded hardware systems without a memory management unit (MMU).
The LEON3 is a 32-bit VHDL processor core based on the SPARCV8 RISC instruction set architecture.
This project will involve synthesis and placement of a LEON3 processor onto a commercial off the shelf (COTS) field programmable gate array (FPGA), μCLinux will then be loaded to the FPGA.

- Download the CentOS distribution, specific .iso files listed above.
- (VirtualBox is used here, however, CentOS could of course be used as the machine's primary operating system). In VirtualBox, create a new virtual machine. Specific options used are described in CentOS_5.3_i386.xml.
- With the new virtual machine, mount and boot to CentOS-5.3-i386-bin-1of6.iso.
- When installing CentOS, install the following extras: "Development Libraries","Development Tools","Java Development","Legacy Software Development".
- Login-name: 'centos' sans single quotes.
- Once CentOS is installed: a. Applications->System Tools->Software Updater
- We know have a fresh, updated operating system to begin the project.
Building uCLinux
Cross Compiler
The cross compiler is necessary to compile μCLinux using LEON3 as the target architecture.
In the CentOS virtual machine, open a terminal.
$ cd $ pwd /home/centos $ mkdir uCLinux $ cd uCLinux/ $ mkdir crosscompiler $ cd crosscompiler/ $ wget ftp://gaisler.com/gaisler.com/linux/linux-2.0/toolchains/sparc-linux-3.2.2/sparc-linux-3.2.2-1.0.1.tar.bz2 $ tar xjf sparc-linux-3.2.2-1.0.1.tar.bz2 $ su Password: $root cp -R ./sparc-linux /opt $root exit exit $ export PATH=$PATH:/opt/sparc-linux/bin
uCLinux Source
We're going to use an instance of uCLinux that is safely ensconced within SnapGear Linux provided by Gaisler. The mainline distribution of uCLinux is rife with 'paper cuts'.
$ cd $ cd uCLinux $ mkdir uCLinux_source $ cd uCLinux_source $ wget ftp://gaisler.com/gaisler.com/linux/linux-2.0/snapgear/snapgear-2.0-p36.tar.bz2 $ tar xjf snapgear-2.0-p36.tar.bz2 $ cd snapgear-2.0-p36 $ make xconfig Kernel/Library/Defaults Selection, Libc Version: uClibc, Customize Vendor/User Settings: Y, 'Save and Exit'. Set Kernel Command Line: n boa 0.94.14rc21: n hdparm: n SnapGear Embedded Linux Application Configuration -> Network Applications, telnetd: n, 'Save and Exit'. $ make dep $ make
Built images will be found at: /home/centos/uCLinux/uCLinux_source/snapgear-2.0-p36/images/
TSIM
Validate the built image by using a LEON3 emulator from Gaisler.
$ cd $ cd uCLinux $ mkdir TSIM $ cd TSIM $ wget ftp://ftp.gaisler.com/gaisler.com/tsim/tsim-eval-2.0.14.tar.gz $ tar xfz tsim-eval-2.0.14.tar.gz $ export PATH=$PATH:/home/centos/uCLinux/TSIM/tsim-eval/tsim/linux/ $ cd /home/centos/uCLinux/uCLinux_source/snapgear-2.0-p36/images/ $ tsim-leon3 $ tsim> load image-2.0.x.tsim $ tsim> run
Building the LEON3
Download Xilinx ISE WebPACK. http://www.xilinx.com/tools/webpack.htm. Make an account and log in. The product you want is: "SW, ISE WebPACK 11.1 Single File Download Image" and the name of the file is "Xilinx_11.1_WebPack_SFD.tar".
$ cd $ cd uCLinux $ mkdir Xilinx_ISE_11 $ cd Xilinx_ISE_11 $ #Place the downloaded Xilinx_11.1_WebPack_SFD.tar into this directory.# $ tar xf Xilinx_11.1_WebPack_SFD.tar $ cd Xilinx_11.1_WebPack_SFD $ su Password: $root echo 0 >/selinux/enforce #to turn off secure linux $root ./xsetup #Keep defaults, except: unselect 'Acquire or Manage a License Key', unselect 'Launch XilinxUpdate'. $root chmod -R 755 /opt/Xilinx/11.1 $root exit exit $ cd /opt/Xilinx/11.1 $ ./settings32.sh $ export PATH=$PATH:/opt/Xilinx/11.1/ISE/bin/lin
With the Xilinx account, request a 30 day trial license, or purchase a license. When the process is complete, you will have a file called 'Xilinx.lic'. Place the file in '/home/centos/.Xilinx/', chmod the permissions to 755.
Now that Xilinx ISE is installed, we'll pull down the LEON3 from Gaisler, and compile.
$ cd $ cd uCLinux $ mkdir LEON3 $ cd LEON3 $ wget http://www.gaisler.com/products/grlib/grlib-gpl-1.0.21-b3848.tar.gz $ gzip -rd grlib-gpl-1.0.21-b3848.tar.gz $ tar xf grlib-gpl-1.0.21-b3848.tar $ cd grlib-gpl-1.0.21-b3848/designs/leon3-xilinx-ml505 $ make xconfig #Tested with enabling and disabling the MMU, both work. OK. $ make ise-map $ make ise #The resulting file is 'leon3mp.bit'.
Program ML505 with μCLinux and LEON3
Install Windows XP SP2 (32-bit) to a computer, install Xilinx ISE 11.1 Design Suite. 'Xilinx_11.1_ISE_DS_SFD.tar' can be downloaded from Xilinx. Disable 'Acquire or Manage a License Key' and disable 'Launch XilinxUpdate'. XP is used to program the board instead of CentOS due to time constraints, everything works without much trouble on XP. A good follow on project would be to program the board using CentOS.
Attach a serial cable from the ML505 to the XP machine. Connect the Xilinx Platform Cable USB from the XP host machine to the ML505. Attach the ML505 to a power source, and turn on. Do not connect to Windows Update to find a driver, allow the driver to be installed automatically.
- Use Xilinx iMPACT to download the leon3mp.bit file to the FPGA.
- Start Xilinx iMPACT, automatically create and save a project->Yes. select 'Configure devices using Boundary-Scan(JTAG)'->OK.
- 'Do you want to continue and assign configuration file(s)?'->No. 'Device Programming Properties'->Cancel.
- On the xc5vlx50t chip, right click 'Assign New Configuration File'. Select the leon3mp.bit. 'Attach SPI or BPI PROM'->No.
- On the xc5vlx50t chip, right click 'Program'. 'Device Programming Properties'->OK.
- Xilinx iMPACT should report 'Program Succeeded'.
- Download GRMON from Gaisler to debug and program the ML505 board.
- ftp://gaisler.com/gaisler.com/grmon/grmon-eval-1.1.37.tar.gz
- Extract to suitable directory.
C:\Xilinx\Tutorials\grmon-eval\win32> grmon-eval.exe -u grlib> info sys
- Load the built image file to execute Linux on the FPGA
C:\Xilinx\Tutorials\grmon-eval\win32> grmon-eval.exe nb -u grlib> load image-2.0.x.dsu grlib> run
Follow On Work
- Benchmarks. SPECint. Compile the core with/without the hardware FPU, and see how much worse SPECfp would be.
- Troubleshoot the μCLinux Official Distribution. Fixing the 'paper cuts', as well as diff-ing the code between official and SnapGear. After fixing and gratuitous documentation, re-committing to the official site.
- SystemACE. Using a CF card to combine the LEON3 bit file as well as the Linux image into a SystemACE file and install onto the CF card that came with the ML505.
- Xilinx ISE Installation to CentOS. There are a myriad of tutorials and papers that touch on various parts of getting the ISE to work. Putting together a single source document with precise steps for Xilinx ISE installation would be useful.
