Freescale offers complementary MQX RTOS suite for its ColdFire microcontroller with full source code. Although the software is deliveried in source code, it is highly recommended not touching source code in the component level.

The default firmware shipped with the M52259DEMOKIT and M52259EVB is Web HVAC, which allows people to view and control HVAC via a standard web browser. It is the 4th lab project in the series of demo projects prepaired for the MCF52259 connected microcontroller. 

In this blog, Kirin stands for a specific product line of ColdFire 32-bit microcontroller from Freescale Semiconductors.

Freescale Semiconductor developed a “one-stop-shop” industrial connectivity solution that combines 32-bit ColdFire mcu family (MCF5225x) with a complimentary offering of the Freescale MQX real-time operating system (RTOS).
