Flash memory not detected - Arria 10 Development kit

hello, We have a new development kit ( Intel Arria 10 GX FPGA Dev board - DK-DEV 10AX115S-A). I can program the sof and do the initial fpga check with blinky LED. Now, I want to try programming the...

Hi,
the board uses 2x1Gbit flash memory, thus memory type should be specified as CFI_2gb.

User manual 6.8.1 shows the default flash memory map. I presume that PFL option bits and factory respectively user hardware (whatever you want to program) should use the defined settings to be recognized by the flash loader at boot time.

You may also check which settings are used in the default factory configuration, e.g. by decoding fpp_config.pof. Usually flash loader is reading option bits to determine where to find the FPGA configuration. Factory configuration DIP switch will be probably used to switch between factory and user configuration, but I'm not sure.

When I were you, I would expext clear instructions how to generate and flash .pof shipped with the board, also example .cof and .cdf files. I took only a brief tour around the support package, but apparently they are not there.
