3.2.6. Programming Serial Flash Devices
You can program serial flash devices in-system using the Intel FPGA Download Cable II or Intel FPGA Ethernet Cable.
You have the following two in-system programming options:
• Active Serial
• JTAG
3.2.6.1. Programming Serial Flash Devices using the AS Interface
When you select AS programming the Intel Quartus Prime software or any supported third-party software programs the
configuration data directly into the serial flash device.
You must set MSEL to JTAG. When MSEL is set to JTAG, the SDM tristates the following AS pins: AS_CLK, AS_DATA0-
AS_DATA3, and AS_nCS0-AS_nCS3. The Intel Quartus Prime Programmer programs the flash memory devices via the AS
header. If you are using the Generic Serial Flash Interface Intel FPGA IP to write the flash memory the flash device must be
connected to GPIO to access the flash device.
