How to program QSPI on custom board

I have a custom board with a Cyclone V (5VSEMA5U3117N) and a QSPI flash memory attached (256 Mbit) to the HPS. I've checked all of the wiring and it looks fine, but when I try to access this memory v...

    Well, after much trying, and getting absolutely no support from Intel, we replaced our ISSI QSPI parts with Micron parts and everything works, now. This was a complete waste of time and Intel not being able to answer simple questions (like what parts are supported) is ridiculous. But we're moving on...

Hello sir,

We are still investigating about this issue.

Currently, there is no method to use non-supported QSPI flash. I understand your point, the Supported flash devices list requires an update.

I will send this request to our internal team for future improvement.

Thanks and apologize for the inconvenience

It's even a bit worse than just "requiring an update". The part Dzar is asking about here, IS25WP256D-RHLE, is the exact part Intel puts on the Cyclone 10 GX Development Kit board Intel sells. The devkit includes parts that aren't even supported by Quartus. This seems to be acknowledged in the Golden Top level, which includes notes like this:

   //QSPI
    output          c10_qspi_clk       , // IP core is currently not available
    inout   [3:0]   c10_qspi_d         , // IP core is currently not available
    output          c10_qspi_csn       , // IP core is currently not available
    output          c10_qspi_resetn      // IP core is currently not available

Is Intel planning to fix this?
