The Firmware Upgrade Over the Air (FOTA) module is a hardware accelerator that is a component of the OptiFlash technology to schedule reads and writes over the same 8 data lines of the OSPI module. The purpose of this hardware accelerator is to minimize XIP downtime.
For applications like ADAS,Automotive Gateway,and IndustryAutomation,Firmware Over the Air (FOTA) updates are required toaddress bug fixes and security vulnerabilities.In order to meet the systemcost,a single flash solution isrequired,which would require topause the application execution until the update (firmware download) is completed. To reduce overall down-time of the system during a firmware update,FOTA allows the system toupdate new firmware/software image during concurrent system operation - reading from external flash (XIP).
For more information on FOTA, see Section 13.3.2.2.6.
