摘要: 在一些对实时性要求高的应用场景,上电后DSP程序就需要运行,如某些伺服电机控制系统,上电就需要电机启动运行,需要等待时间的传统在线升级方式就不再适用。提出了一种通过RS422接口发送BIN文件至TI C2000系列DSP SCI接口进行实时在线程序升级的新方法,可以在满足程序在线升级的同时,具备上电实时启动系统的要求。

Abstract: In some application scenarios with high real-time requirements, the DSP program needs to run after power on, such as some servo motor control systems, the motor needs to start running after power on, the traditional online upgrade method that requires waiting time is not applicable. A new method of sending BIN files to TI C2000 series DSP SCI interface through RS422 interface for real-time online program upgrade is proposed, which can meet the requirements of online program upgrade while having power on real-time system start up.
