摘　　要：目前对个人笔记本电脑的EC固件更新软件都是基于X86架构CPU开发的,随着搭载国产飞腾CPU新型个人笔记本电脑的出现,我们不可避免地面对许多底层芯片固件更新软件无法在飞腾RAM架构平台上运行的问题。目前针对搭载飞腾CPU的笔记本电脑,EC芯片固件更新只能采用将EC固件的Flash拆下来进行离线烧录的方法,该方法费时费力,还很容易损坏主板,提出以一种在Linux操作系统下对EC固件进行更新的方法,提高调试效率,节约售后维护成本。At present,EC firmware update software for personal notebooks are all developed based on X86 CPU architecture.With the emergence of new personal notebooks equipped with Phytium CPU,we inevitably face the problem that many underlying chip firmware update software cannot run on ARM architecture platform of Phytium.Currently,for notebook computers equipped with Phytium CPU.The EC chip firmware can only be updated by tearing down the EC Flash from the mainboard and burning it offline,which is time-consuming and laborious.It’s also possible to damage the motherboard.This paper presents a method to update EC firmware in Linux operating system to improve debugging efficiency and save maintenance cost.
