摘要

介绍了屏蔽门DCU的双处理器（TMS320F28335、PIC24FJ64GB004）架构，详细论述了PIC24FJ64GB004通过远程通信更新固件的方法。通过试验，证明此方法稳定、可靠，避免了利用仿真器或编程器更新固件的不便，提高了系统的可维护性。因不依赖于特定处理器与通信介质，此方法完全适用于其他应用。

Abstract

Dual CPU(TMS320F28335, PIC24FJ64GB004) architecture in DCU of PSD was introduced, and method of firmware remote updates for PIC24FJ64GB004 was discussed in detail. The method was proved stable and reliable through experiments, and avoided using the emulator or programmer to update the firmware for the inconvenience, which improved system stability. Because of no depending on the specific processor and a communication medium, this method is fully applicable to other applications.
