1 Introduction
This application note is a supplement to AN4287: MQX Board
Support Package Porting Guide, available on freescale.com.
AN4287 introduced how to create new BSP in CW7.2, CW10
and IAR, but didn't cover KEIL embedded development
products. So, this application note introduces how to create a
new BSP in KEIL for porting. In addition, this document also
introduces a script tool to help make this procedure much
easier. All the discussion in this application note is based on
Freescale MQX
™
RTOS 3.8.0.
2 Introduction to MQX’s BSP
BSP masks the hardware details and provides the uniform
interface to the operating system (OS). Before beginning to
port a BSP for MQX, it must be known how MQX is
organized and how it works.
Figure 1 shows the folder organization of MQX. The folders
enclosed by red rectangular boxes (as shown in Figure 1) are
significant while porting a BSP. The contents of these folders
are described briefly as follows.
