摘要
ColdFire系列微处理器是Freescale32位微处理器的主流产品,采用先进的BDM调试接口技术。在分析了BDM接口特点、通信时序基础上,提出了BDM调试器基于CPLD器件的硬件设计方案,阐述了BDM调试系统驱动程序设计方法。本设计方法在实际中取得了良好的使用效果。
ColdFire family MCUs which use advanced BDM debug interface technology are the mainstream products of Freescale 32- bit microcontrollers. After analyzing the features and communication sequence of BDM＇interface, this paper raises the hardware design of the interface, expounds the method of hardware design based on CPLD and gives the design of lower and upper driver. This method has made good use of effects in practice.
