What’s openwrt? in my mind,openwrt is running on the embedded device linux systems.
OpenWrt file system is writable, developers do not need to recompile after each modification,
Make it more like a mini Linux computer systems, but also accelerated the development speed.
You will find both the ARM, PowerPC, or MIPS processor, has a very good support.
And with around 3000 packages, users can easily customize the features to make the firmware.
Can be easily ported to various types of functions under openwrt.
