提出了一种基于GoAhead嵌入式web服务器和JTAG总线的FPGA/CPLD/PROM器件远程配置方法。设计使用GoAhead嵌入式服务器接收来自以太网的XSVF文件,再由CPU解析并通过JTAG协议对FPGA/CPLD/PROM进行配置文件更新,技术人员可以通过局域网中的任意PC机对目标设备进行远程操作,避免了繁琐而不安全的设备开箱。本方法占用系统硬件资源极少,效果稳定可靠,可作为各类通信设备中FPGA/CPLD/PROM器件的ISP方案,也可方便的用在旧设备的升级改造中。
A remote configuration method of FPGA / CPLD / PROM device based on GoAhead embedded web server and JTAG bus is proposed. The design uses the GoAhead embedded server to receive the XSVF file from the Ethernet, then the CPU parses and updates the FPGA / CPLD / PROM configuration file through the JTAG protocol. The technician can remotely operate the target device through any PC in the LAN, Avoid tedious and insecure equipment out of the box. The method occupies very little system hardware resources, the effect is stable and reliable, and can be used as an ISP solution for FPGA / CPLD / PROM devices in various communication devices, and can also be conveniently used for upgrading and upgrading old devices.
