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. Bootlets are stable, Das U-Boot is worked on

and has support for the boards since recently.

  • kernel, usually comes from the distribution or build system being used
  • root filesystem, also provided by the chosen software distro

Kernels

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

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
