1.2.1. Remote System Configuration Mode
Remote configuration supports “Direct to application” (DTA) and “Application to Application” update. Remote configuration only supports a 4-byte address scheme so there is no support for devices with densities smaller than 128 Mbit.
The CRC check on the application image is done taking only image data into consideration. Dummy bytes in programming files are not taken into account during CRC checks.
When you use low-voltage quad-serial configuration (EPCQ-L) devices, the remote update mode allows a configuration space to start at any flash sector boundary. This capability allows a maximum of 512 pages in the EPCQ-L256 device and 1024 pages in the EPCQ-L512 device, in which the minimum size of each page is 512 kilobits (Kb). Additionally, the remote update mode features an optional user watchdog timer that can detect functional errors in an application configuration.
