Version 1.4 Released

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&#39;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&#39;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.
