- Download the Linux package for CL-SOM-iMX6 from CompuLab website. Unzip the package to a directory on your host workstation.
- All image files mentioned below can be found in the images subdirectory.
- Connect the host PC to the SB-FX6 base-board (connector P8) via the serial cable supplied with the evaluation kit.
- Continue to the Preparing installation media subsection.
Preparing installation media
- Obtain an MMC/SD card. Any commercially available MMC/SD card of 1GB (or larger) may be used.
- Create a first partition on it. The partition can be formatted either ext2/3/4 or FAT file system.
- Copy all files found in the directory images from the Linux package for CL-SOM-iMX6 to the first partition on the installation media (MMC/SD card).
- Continue to the Automatic Installation Procedure section.
