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 image (recommended):

Torrent of Arch Linux release 5 for all Olimex iMX233 boards: iMX233 Arch image with kernel 2.6.35 WIFI release 5

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.
• minifs Compact Linux Distro Generator for iMX233 with mainline Kernel 3.x
