The current MDK (Mity Development Kit) for this module is an extension the TI Processor SDK. The MDK is created using Yocto and includes a cross-compiler environment along with Kernel, U-Boot, and filesystem binaries. In general, we recommend using Ubuntu Linux distribution for development. Using a older, but still supported, LTS release is usually the best choice.

Downloads of Critical Link maintained packages can be found under the "Files" tab or directly at: Also, larger files (including source code for the MDK Yocto build) are available at
