Linux for the Nios II Processor
Please refer to http://www.rocketboards.org/foswiki/Documentation/NiosIILinuxUserManual for latest updates on Nios II Linux !
This is the community supported version of Nios II Linux with MMU. This package will work only on Linux. You will need a virtual Linux to run it on Windows. This is GPL software, and comes with absolutely NO warranty.
Getting started with Linux for the Nios II processor
- Linux desktop installation
- Download Linux distribution for the Nios II processor
- Quick start
- Creating a Nios II design with a memory management unit (MMU)
- Debug user space
- Try out without compilation
- Build the gcc4 toolchain
- Device tree
- KGDB (Kernel Debugger)
- Linux Sources
- Nios2 SMP Linux System
- Kernel development is currently taking place in the "unstable-nios2mmu" branch of the git repository. It is stable despite the name and frequently gets updated with the most recent upstream changes. The branch contains code to run Linux on Nios II with or without MMU. So to build a current (2.6.39 as of this writing), you need to switch to that branch for the kernel. Inside the "linux-2.6" folder, issue a "git checkout unstable-nios2mmu" command to switch your head to that branch. Alternatively you can check out a stable tagged version. These are recognizable by their -nios2 prefix. To e.g. check out Linux Kernel 2.6.39 with Nios II support, issue "git checkout v2.6.39-nios2".
- If you want to build a recent Linux kernel for Nios II without MMU, please see the message announcing the merge of the MMU and NOMMU tree at http://sopc.et.ntust.edu.tw/pipermail/nios2-dev/2011-March/005041.html for some important instructions
- As of this edit (March 21, 2011), this page is somewhat out of date but it still contains the best information for getting Linux up and running on a MMU based NIOS processor. A comprehensive update is coming soon but for now I am adding "ugly" edits to note bugs / errors in the build instructions.
Many informations provided for the no-MMU uClinux distribution on this Wiki also applies to the MMU based Linux installation.
