4.2. How the HPS Flash Programmer Works

The HPS flash programmer is divided into a host and a target. The host portion runs on your computer and sends flash programming files and programming instructions over a download cable to the target. The target portion is the HPS in the SoC. The target accepts the programming data flash content and required information about the target flash memory device sent by the host. The target writes the data to the flash memory device.

The HPS flash programmer determines the type of flash to program by sampling the boot select (BSEL) pins during cold reset; you do not need to specify the type of flash to program.
