Building the AVR32 Linux file system for the STK1000

Introduction

A prebuilt AVR32 Linux image for the STK1000 can be found in the BSP CD at /BSP-CD/builds/stk1000/avr32-linux-image.img.gz.

The BSP CD includes a reference script that builds an AVR32 Linux file system image. The reference script is available from: /BSP-CD/scripts/build-linux-environment.sh.


NOTE: Windows does not support the second extended file system (ext2), and the Linux kernel is not guaranteed to build under cygwin, so this can only be done when running Linux on your host machine.

Running build-linux-environment.sh

build-linux-environment.sh can be run as follows:

  • Copy source and script from BSP CD to a local folder: 
mkdir /home/stk100build
cd /home/stk1000build
cp -r /bsp-cd/scripts .
cp -r /bsp-cd/software .
  • Copy and unpack the linux reference file system. 
cp /bsp-cd/builds/stk1000-linux-image-reference.tar.gz .
tar -zxf stk1000-linux-image-reference.tar.gz
  • Make a build directory 
cd scripts
mkdir build
  • Edit the reference script (adjust configure settings, select modules and so on)
  • Run build-linux-environment.sh 
bash ./build-linux-environment.sh ../software ../sd-image-reference build

Once you have built the file system image you can write it to an SD card or mount the filesystem over NFS

Troubleshooting

  • Make sure to have installed all the necessary tools. This includes both tools specific for the AVR32 and general build tools. See AVR32 Tools Installation
  • If you want to change settings:
    • Edit build-linux-environment.sh to remove or add packages.
    • Edit configure files included in each package to change settings.
