Design of Embedded Remote Software Update System Based on FPGA+ARM

Abstract

Software updates are one of the most critical considerations in the production phase of any IoT project at a very early stage. If a production team maintains the program, anything that goes wrong can be corrected, and new characteristics can be implemented promptly, provided remote upgrades are successful, secure, and trusted. The fast growth of embedded and wireless technologies has eventually led to the convergence of embedded and wireless systems. Therefore, products should be pushed into development beforehand to provide the potential for a different approach, including remote upgrades if new enhancements are ready or if bugs have been remedied with the existing version. For the most part, it’s good to have a software upgrade mechanism during the very early stages of the product or application definition. The paper offers an ARM and FPGA-based data acquisition framework. It aims to capture the bandwidth of wireless signals from 70[Formula: see text]MHz to 6[Formula: see text]GHz using the proposed framework in the article. The framework included the user interface to configure sample rate, bandwidth, sample center frequency, sample time, and data storage parameters for sampling — the proposed framework consists of software and software architecture for the hardware framework. The hardware is supported by ARM and FPGA. The software is based on the Xilinx software development kit (SDK). In particular, for fast transmission and storing of data over ETHERNET, a remote data acquisition scheme based on the server and client model is built.
