question about QSPI core

[dsun01]

Dear Intel Support and Expert

I am working on a QSPI project, the target device is STHV1600 from ST. the chip control is like QSPI, but I think need some customization.  

If there is no QSPI IP core that I can use directly. is it possible to make some modification of a standard QSPI core?  I hope it will save some time if there is someone already invented the wheel. 

Appreciate your help. happy holiday,

David

Hi,

Not sure if you are able to use https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-gen-sfi.pdf? I don't think you are able to modify the QSPI Core IP as it is part of the Quartus IP.

Hi John

thank you for the reply, if there is no similar core that I can use, is there a solution that use the NiosII IO to emulation a Quad-SPI? if true, is there are example how to use NiosII implement an SPI through the IO pin instead of a SPI MASTER core. 

Best Regards,

David
