Altera_Forum · ‎06-28-2005

The Microtronix Nios II Linux Distribution has been updated to support the Nios II 5.0 IDE.

Following is a partial list of changes from v1.3 of the distribution to v1.4:

- The Linux kernel has been upgraded from v2.6.9 to v2.6.11

- Support for the Altera Nios II 2s60 ES Development board is now included

- Support for the Microtronix PSK is also provided.

- The application plug-in was re-written to support the newer version of Nios II IDE (specifically, the newer CDT)

I'll be using this thread to post any updates and bug-fixes that can be applied to v1.4 of the Nios II Linux Distribution. Please feel free to subscribe to this thread to keep notified of these fixes.

The following info is also found within the readme.txt file.

upgrading from v1.x to v1.4

backing up your projects:

To carry your kernel projects forward to the new release, please backup

the <project>/build/.config file to somewhere safe.

To carry forward filesystem and application projects, please backup each

project directory to somewhere safe.

All projects can normally be found in:

...altera/kits/nios2/bin/eclipse/workspace

upgrade procedure:

(1) Uninstall Nios II Linux v1.x.

(2) Follow the upgrade procedures for Quartus II v5.0 and Nios II v5.0

(3) Install Nios II Linux v1.4

restoring a kernel project:

(1) Create a new kernel project using the instructions found within the Quickstart Guide. The procedure hasn't changed at all since v1.0

(3) Configure the kernel taking all the defaults.

(2) Copy over the .config file that you backed up earlier into the project's build directory.

(3) Start up Nios II SDK shell and run:

$ cd $ECLIPSE_WORKSPACE/<kernel_project>/build
$ make oldconfig

When prompted with new options, select "no" for any new ones that show up. In the case of multi-answer options, using the default value should be safe.

(4) From within the Nios II IDE, try rebuilding the kernel using the build project option.

restoring filesystem projects:

(1) Copy the project directories back into the main workspace directory that you selected when starting up the Nios II v5.0 IDE.

From the Nios II IDE:

(1) Select File->Import... from the pull-down menus

(2) Select "Existing project into Workspace" from the list of options

(3) Click next.

(4) In the next page, select: "Browse..." and select the project directory with your filesystem project.

restoring application projects:

(1) Create a new Application Project using the Nios II IDE.

(2) Copy all the relevant C Source files and Makefiles into your new application project and build.
