7.8.3. Programming EPCS and EPCQ Devices

You can program EPCS and EPCQ devices in-system using a USB-Blaster™ , EthernetBlaster, EthernetBlaster II, or ByteBlaster™ II download cable. Alternatively, you can program the EPCS or EPCQ using a microprocessor with the SRunner software driver.

In-system programming (ISP) offers you the option to program the EPCS or EPCQ either using an AS programming interface or a JTAG interface. Using the AS programming interface, the configuration data is programmed into the EPCS by the Intel® Quartus® Prime software or any supported third-party software. Using the JTAG interface, an Altera IP called the serial flash loader (SFL) must be downloaded into the Cyclone® V device to form a bridge between the JTAG interface and the EPCS or EPCQ. This allows the EPCS or EPCQ to be programmed directly using the JTAG interface.
