Research and Implementation of Online Upgrade Technologies for DSP
This paper develops an online upgrade plan based on In-Application Programming (IAP) for the software upgrade problems of digital signal processor (DSP). Taking TMS320F28335 as an example, the online upgrade of application is achieved through the secondary Bootloader. The key technologies such as Flash space allocation, program startup design, Flash API usage, and software upgrade process design are detailed. The experimental result suggests that this plan is convenient, secure, and reliable, and has high promotion value.
