IMX233

Official Images from OLIMEX

Linux

For initial test with the default images follow the general algorithm:

1. Download the image

2. Extract it out of the archive

3. Write the image to a properly formatted microSD card

Step 3 under Linux looks usually like:

sudo dd if=LINUX_IMAGE_NAME.img of=/dev/mmcblk0

Newest official Arch Linux images (recommended):

If you experience problems or instability with one of the images below please test with the other! Different iMX233 boards have different memories and this requires different images.

Torrent of Arch Linux release 4 for Olimex iMX233 boards with SAMSUNG RAM memories: iMX233 Arch image with kernel 2.6.35 WIFI release 4

Torrent of Arch Linux release 3 for Olimex iMX233 boards with industrial or non-SAMSUNG RAM memories: iMX233 Arch image with kernel 2.6.35 WIFI release 3

Build instructions for the ArchLinux images: GitHub instructions; the difference in the source code between the two official releases is in init-mx23.c related to the RAM initialization, refer to this forum post

Software

Linux Commands

Linux-Commands Brief Linux Command reference

To run a Linux system on iMX233 boards, 3 key components are required:

• boot code: either bootlets or a bootloader;
• kernel;
• root filesystem.
  
  

Kernels

There are two kernel flavours which work on all 3 iMX233 OLinuXino boards:

• 2.6 line. Support for all on-board hardware features, but lacks support for new kernel features and drivers. Build recipes: Yocto BSP, ArchlinuxARM package.
• Mainline. A modern kernel but still a bit flaky. instructions, easy build helper with instructions, PKGBUILD for alarm.
  
  
  

Software Distributions

A list of linux distributions or build systems which can produce runnable images:

• Debian. An excellent guide here, including instructions for bootloader, SD card partitioning, etc. There is another guide from Olimex.
• ArchlinuxARM with packages for both 2.6 and 3.x kernels and rich package repositories. The prebuilt images use bootlets, but can be made to work with U-Boot.
• Yocto BSP, where most of the work on the boards is done and integrated first. Not newb-friendly, but extremely powerful. Also a complete SDK with cross-toolchains, runtime libraries, etc.
