Hardware

Attaching LCD to iMX233-OLinuXino-MAXI

Software

To run a Linux system on these 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
