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...

I am making progress. I did find that the CE# pin (that's also BSEL1) was pulled up with a zero Ohm resistor. So I fixed that to be 1K and now I can see an ID.

But the ID is odd...

I see 9D19709D.

If the first 9D was not there, it would be what I expect, but my part says it repeats the sequence until CE# is brought high, again. But quartus_hps seems to read more than three bytes and then complains that this is not a valid ID and won't do anything more.

....

Clock Select: 0

Start HPS Quad SPI flash programming ...

Initialize QSPI peripheral and flash controller ...

Assuming QSPI controller system clock is 50Mhz

QSPI controller baudrate setting: 32 (15)

Read Silicon ID of Quad SPI flash ...

Quad SPI Flash silicon ID is 0x9D19709D

Error: Not able to map flash ID from flash database

Error: Quartus Prime Programmer was unsuccessful. 0 errors, 0 warnings

Error: Peak virtual memory: 4273 megabytes

Error: Processing ended: Fri Nov 30 21:45:48 2018

Error: Elapsed time: 00:00:02

Error: Total CPU time (on all processors): 00:00:00

Is there anything else one could try, here?

Thanks
