Why is EPCS_controller not supported in Quartus 18.0 for Cyclone 10 LP

You probably have to update/regenerate the IP, but EPCS support is going away:

Hi WMor,

The EPCS/EPCQA serial flash controller core is not supported by Intel Cyclone10 LP devices.

Kindly check the below link (15.1 Core Overview) - Page 165

Check the below thread with similar issue.

Thanks.

Hello sstrell and Calvin Joazer,

Thank you both for taking the time for answering my question.

In the mean time I also learned that I should use ASMI Parallel FPGA IP Core for configuring the Cyclone 10 LP. Are there some documents how to connect an EPCS devices to a Cyclone 10 LP and how to configure the ASMI Paralell FPGA IP Core in the Platform Designer (how to connect this to the NIOS II CPU)?

Thank you and best regards,

Wamor​

Hi WMor,

Refer to the link below for 'ASMI Paralell IP Core' or 'ASMI Parallel II IP' which has similar feature.
