TMS320F28335 Online Program Upgrade Realization Method

A method of programming to FLASH using asynchronous serial communication interface SCI is proposed. By changing the FLASH boot mode of TMS320F28335 and entering the pre-burned upgrade program, the serial port online upgrade program can be realized. This article introduces the principle and implementation steps of the method in detail, and gives a flowchart and key codes. The experimental result shows that the method is effective and feasible, which can be convenient to operate and reduces the risk of program upgrade.
