Introduction to openwrt flash partitioning

I used to be engaged in the development of IP camera and involved a small number of Flash layer development tasks. I only had some basic information about our internal flash partitions and the upgrade process, there are still many differences with vrouters, and there are still many skills to master.

In this case, the flash layout http://wiki.openwrt.org/doc/techref/flash.layout on openwrt has the most official explanation.

In fact, openwrt currently supports automatic partitioning of Flash partitions. You only need to specify the firmware size in the DTs file.
