Research on Online Program Upgrade Method Based on TMS320F28388D

TMS320F28388D, as a new Digital Signal Processor (DSP) produced by Texas Instruments in recent years, has gradually been applied in various fields due to its strong performance. The official program update download method often requires opening embedded devices or configuring additional I/O status, which is not applicable in many scenarios. This article proposes an online upgrade method that does not require additional operations on embedded devices to address this issue. This method involves designing the BootLoader on the DSP side and the software on the personal computer side separately. The BootLoader is solidified to the DSP, and then the update file is automatically downloaded to the DSP using a personal computer via serial communication. Finally, the feasibility of this method was verified on the development board.
