*************************************************************************************************************** Project : Linux BSP for Embedded System Development Kit Cyclone III (3C120)** File Name : Linux_3c120_README.txt** Last Updated : 4th August 2009** Author : System Level Solutions*************************************************************************************************************Quick Start Guide————————–We assume that you are acquainted with Linux enviornment.1. Install the following development packages at host side by giving following command. #apt-get install git-all git-gui tcsh make gcc ncurses-develbison byacc flex gawk gettext ccache zlib-devel gtk2-devel lzo-devel pax-utils2. Download the Linux BSP source (Nios2Linux-20090804-0.0.0.0.tar.bz2) and quick reference ( Quick_ref-20090805-0.0.0.0.tar.bz2) from http://www.slscorp.com/pages/bsp3c120.php Size : 508.44 MB Source : Nios2Linux-20090804-0.0.0.0.tar.bz2 MD5SUM : 4c54f86ef036591a53d18ac8bf6c7bf9 Size : 3.67 MB Source : Quick_ref-20090805-0.0.0.0.tar.bz2 MD5SUM : adee59e8100e3d113e40ed5fed529f4b3. Copy the BSP source ‘Nios2Linux-20090804-0.0.0.0.tar.bz2’ at the development folder on your linux PC and extract it. Ex: #cd /home/sls/ #tar -jxvf Nios2Linux-20090804-0.0.0.0.tar.bz2 The ‘Nios2-Linux’ folder will be created. It contains following three folders. BuildTools : Prebuild bin tools gcc 1.1.2 for nios2-linux Linux_source : Kernel and Application System-Board : System file for specific board. It contains only for 3c120 board files4. Set the Bintools path on your terminal. Ex: #PATH=$PATH:/home/sls/Nios2-Linux/BinTools/toolchain-mmu/x86-linux2/binPATH=$PATH:/home/grant/Nios2-Linux/BuildTools/toolchain-mmu/x86-linux2/bin (每次打开终端都要添加一次） 查看：echo $PATH sudo ln -s /lib/libncurses.so.5 /usr/lib/libtinfo.so.5 —只需要这么一句话！原因参考下文转载注意！： # nios2-wrs-linux-gnu-gcc hello.c -o hello —交叉编译Step 1：所有要打包成image的檔案，都會放在/home/grant/Nios2-Linux/Linux_source/uClinux-dist/romfs下，也就是說，我們只要將執行檔、函式庫、圖片….放在這個目錄下，將來就會打包成zImage下載到开发板的SDRAM內。(或者將hello_world_linux放到/uClinux-dist/romfs/usr/bin下类似[root@localhost src]# cp hello_world_uclinux /usr/local/src/uClinux-dist/romfs/usr/bin )5. Build the Linux image.cd /home/grant/Nios2-Linux/Linux_source/uClinux-dist/ #make menuconfig #make After compilation, you will get different images in the image folder located at: /home/sls/Nios2-Linux/Linux_source/uClinux-dist/image/ The linux.initramfs.gz file is an elf image with initramfs, built-in with u-boot images (images/vmImage and rootfs.initramfs.gz).6. Download the .elf and .sof files and then run the elf file. (a) Download the sof file ‘nios2_linux_3c120_125mhz_top.sof’ located at /home/sls/Nios2-Linux/System-Board/3c120_default/ (b) Download elf file ‘linux.initramfs.gz’ located at /home/sls/Nios2-Linux/Linux_source/uClinux-dist/image/ (c) You will get Linux booting masseges on the nios2-terminal window. #nios2-configure-sof "路径名".sof eg:#nios2-configure-sof C:/nios2_linux_3c120_125mhz_top.sof Ex: #nios2-download -g linux.initramfs.gz eg:nios2-download -g C:/linux.initramfs.gz #nios2-terminal验证结果： Welcome to NiosIILinux ls执行： ./helloNote: — Release is tested on fedora 8 only.
