CDK4NIOS -- NIOS Cross Development Kit
CDK4NIOS stands for Cross Development Kit for Alteras soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment for even this processor familie under Linux. It will present only free of fee tools, so you can use it without risks. Further you will find some useful OS projects and related sample code all arround NIOS inside of the example packages.
CDK4NIOS collects all programms and development tools in one directory (/opt/cdk4nios) and will try to present an easy to admin installation. My intention for CDK4NIOS is / was to provide a full featurd tool chain distribution of all the free accessible resources, because often the most stuff is hidden or scattered to the wide of the whole Internet and only compilable and translatable by wizards or professions.
Basically CDK4NIOS is based on the GNUPro Tool Suite for NIOS maintained by Altera only. You can find a download instruction here (outdated, download latest release 3.2 here). Til now Altera has have support only Win32 systems, HP-UX, and Solaris as developer plattform. So, CDK4NIOS tried out to close this gap. In the near future CDK4NIOS could be become redundant, because Altera planes support for Linux development systems with its latest NIOS release version 3.1 (date: 2003/10/31). Even this was the intension of CDK4NIOS.
The most packages are untested. Some few packages will be unstable or developer snapshot code. So I'm looking for (beta) test users. Please tell me your experience with CDK4NIOS. Further I try to be up to date with all the package versions, but CDK4NIOS is a leisure-time project and so I think my update cycle will be 5 or 7 months, sorry :-(
The base package cdk-nios-base will work only at Red Hat based distributions (Red Hat, Mandrake, and I believe SuSe). For other distributions you have to ensure the linked scripts cdk4nios.sh and cdk4nios.csh in /etc/profile.d are involved in your user environment build process at login time.
Til now Altera has made two major and some minor releases of its NIOS GNUPro. Each release has got its own "major.minor" version number. This version number is absolutely independent of binary versions (assembler, C/C++ compiler, libraries, and debugger). For a better overview related to Altera's work CDK4NIOS uses the GNUPro version number as main counter. The list below should you give a more extensive overview of binary versions related to GNUPro version number:
Each package will be provided as RPM only. It is not necessary to install all packages,but you have to install the base package cdk-nios-base every time you want to use another package. Here is an example for a typical GNU development environment:
[user@host]$ rpm -hiv cdk-nios-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hiv cdk-nios-binutils-3.1-20031023.i386.rpm
[user@host]$ rpm -hiv cdk-nios-gcc-3.1-20031023.i386.rpm
[user@host]$ rpm -hiv cdk-nios-gcc-c++-3.1-20031023.i386.rpm
[user@host]$ rpm -hiv cdk-nios-libgloss-3.1-20031023.noarch.rpm
[user@host]$ rpm -hiv cdk-nios-newlib-3.1-20031023.noarch.rpm
[user@host]$ rpm -hiv cdk-nios-libstdc++-3.1-20031023.noarch.rpm
[user@host]$ rpm -hiv cdk-nios-gdb-3.1-20031023.i386.rpm
Note: Under Linux you don't need to install the package cdk-nios-related-tools. It includes development tools which in most of all case are already installed on a running Linux host system. This package is part of CDK4NIOS to present NIOS GNUPro Tool Suite completely.
Currently you will found all released files at SourceForge.Net
Securety: Each package will be signed by my own PGP key. You can donload my public key (GnuPG: pgp.asc) install it and check the RPM packages. Do this:
[user@host]$ gpg --import pgp.asc
[user@host]$ rpm --checksig *.rpm

Base package -- is needed every time you will use any CDK4NIOS package.
NOTE: Users of base packages with version 0.2 and prior have to update to latest version. There was a damaged (t)csh startup script. As a result of an buggy %preun script in previous packages you have to update in two cycles:
[user@host]$ rpm -hUv cdk-nios-base-0.3-20031111.i386.rpm
[user@host]$ rpm -hUv --force cdk-nios-base-0.3-20031111.i386.rpm

| 1. Assembler, Disassembler, Object File Operator: | |||
| 1.1 | cdk-nios-binutils |
Binutils is a collection of binary utilities, including:
|
|
| 2. Compiler, Interpreter: | |||
| 2.1 | cdk-nios-gcc |
A compiler aimed at integrating all the optimizations and features
necessary for a high-performance and stable NIOS development
environment. You'll need this package in order to compile
C/C++ code. It includes:
|
|
| 3. Debugger, Simulator, Emulator: | |||
| 3.1 | cdk-nios-gdb |
GDB, the GNU debugger, allows you to debug programs written in C, C++,
and other languages, by executing them in a controlled fashion and
printing their data. In the case of NIOS processores you can use a
integrated simulator to run programs. This collection includes:
|
|
| 4. Libraries, Operating Systems: | |||
| 4.1 | cdk-nios-libgloss |
This is `libgloss', the library for GNU Low-level OS Support, contains the startup
code, the I/O support for gcc and newlib (the C library), and the target board
support packages which you need to port the GNU tools for an embedded
execution target. You need to install NIOS libgloss to use NIOS newlib port.
|
|
| 4.2 | cdk-nios-newlib |
This is `newlib', a simple ANSI C library, math library, and collection of
board support packages. You need to install NIOS newlib port to work
with C source files or to use NIOS libstdc++ port.
|
|
| 4.3 | cdk-nios-libstdc++ |
This is the standard C++ library supported by GNU CC. You need to
install NIOS libstdc++ port to work with C++ source files.
|
|
| 4.4 | cdk-nios-uclibc |
This is `uClibc', the microcontroller C library as an alternative to the
common used GNU Lib C. The uClibc will be used together with uCLinux.
Till now the uClibc-toolchain is completely untested so there is no way to
install/use the uClibc library together with the other ones above (newlib & Co.).
Note: This library is in BETA stage for Nios (especialy CDK4NIOS). So there may be left some board/target specific dependencies. This binary package was only tested successful on Alteras Nios Development Kit DK1S10 Stratix Edition. If you want to rebuild the library in a special way with your own configuration you can install the package cdk-nios-uclibc-source and use the content of the source path /opt/cdk4nios/src/uClibc. To do this you need a full configured uCLinux source tree (see cdk-nios-os-uclinux-source below). Quick Start: To rebuild the uClibc together with your own linux kernel - in this example with the kernel rebuild for DK1S10 (see below) - do this (you need the toolchain without standard libraries):
Coming soon: ... collection of usable and workable userland applications ... For more informartion see: http://www.uclibc.org |
|
| 4.5 | cdk-nios-os-uclinux |
This is `uClinux', the microcontroller Linux kernel for MMU less CPUs as an special
port to Alteras Nios Soft CPU. The Linux kernel is already ported to:
Note: The uCLinux kernel is in BETA stage for Nios (especialy CDK4NIOS). This binary package was only tested successful on Alteras Nios Development Kit DK1S10 Stratix Edition. If you want to rebuild the kernel in a special way with your own configuration/changes you can install the package cdk-nios-os-uclinux-source and use the content of the source path /opt/cdk4nios/src/linux. Quick Start: To rebuild the uCLinux kernel for DK1S10 do this (you need the toolchain without standard libraries):
