Software Files
The EPCS serial flash controller core provides the following software files. These files provide low-level
access to the hardware and drivers that integrate into the Nios II HAL system library. Application
developers should not modify these files.
•
altera_avalon_epcs_flash_controller.h , altera_avalon_epcs_flash_controller.c —Header and source files that
define the drivers required for integration into the HAL system library.
• epcs_commands.h , epcs_commands.c —Header and source files that directly control the EPCS device
hardware to read and write the device. These files also rely on the Altera SPI core drivers.
