5.4. Quad SPI Flash Layout
5.4.1. High Level Flash Layout
5.4.1.1. Standard (non-RSU) Image Layout in Flash
In the standard (non-RSU) case, the flash contains four firmware images and the application image. To guard against possible
corruption, there are four redundant copies of the firmware. The firmware contains a pointer to the location of the application
image in flash.
