Sd card to update the firmware of module instead of doing by swiflash tool


i am currently using mangoh green board and using swiflash tool to flash target module.
I want to update WP85XX firmware with just plugging in SD card which have an image of yocto build inside it.
so we would not have to use swiflash on field product if there is any update in s/w required in existing products having WP85XX module.
help me if there is any thing similar to my requirement.



Can you have a look at the fwupdate tool. Below is the link for your reference:
