All you need to instal nios2-linux is to install following packages: git-all git-gui make gcc ncurses-devel bison byacc flex gawk gettext ccache zlib-devel gtk2-devel lzo-devel pax-utilslibglade2-devel uboot-tools
Next you need download from git all needed sources:
git clone -b trunk git://
sopc.et.ntust.edu.tw/git/uClinux-dist.git git clone git://
sopc.et.ntust.edu.tw/git/toolchain-mmu.git git clone git://
sopc.et.ntust.edu.tw/git/linux-2.6.git git clone git://
sopc.et.ntust.edu.tw/git/tools.git Now you need to set eviroment path in .bashrc file. My looks like follows:
---------------------------------------------------------------
QUARTUS=/home/kamil/altera/12.1/quartus
export QUARTUS
NIOS2EDS=/home/kamil/altera/12.1/nios2eds
export NIOS2EDS
SOPC_KIT_NIOS2=/home/kamil/altera/12.1/nios2eds
export SOPC_KIT_NIOS2
NIOS2LINUX=/home/kamil/uClinux
export NIOS2LINUX
PATH=$QUARTUS/bin:$QUARTUS/sopc_builder/bin:$NIOS2EDS:$NIOS2LINUX/toolchain-mmu/x86-linux2/bin:/usr/bin:$PATH
export PATH
---------------------------------------------------------------------------
In that way I have path for every tool from Altera like also for toolchain for nios2-uclinux.
Last step is to make sopc2dts tool. Just do "make" command in /tools/sopc2dts/ location (for that you need jdk-devel package)
And that is all. Now you can play with linux on your nios2 boards :)
