摘要
通过对GD32的在应用编程(IAP),设计出一种可靠的远程升级方案,在利用现有通信接口的条件下,无需操作微处理器的BOOT信号以及连接升级线缆,对GD32微处理器的应用程序实现软件升级。该方案在保证升级成功可靠的条件下,节省了以往远端设备升级时由于拆卸升级线缆所带来的人力成本和时间成本,对于包含多个嵌入式系统设备的远程在线升级具有一定的参考意义。
A reliable remote upgrade scheme is designed through the in application programming(IAP)of GD32.Under the condition of the existing communication interface,it is unnecessary to operate the BOOT signal of the microprocessor and connect the cable to upgrade the application program of GD32 microprocessor.Under the condition of ensuring the success and reliability of the upgrade,the scheme greatly saves the labor cost and time cost caused by dismantling the upgrade cable in the past,which has a great reference value for the remote online upgrade of multiple embedded-systems equipment.
