Can EPCQL256 be used as configuration device for 5CEFA9?

Hi XG Kang ,

EPCQ-L flash device family only compatible with Intel® Stratix® 10, Intel Arria® 10, and Intel Cyclone® 10 GX FPGAs. (NOT compatible with Cyclone V)

Please refer to following link for more details:

Alternatively, you also can use 3rd party Intel devices supported by Intel® Quartus®.

Please refer to the following link for more details (go to option Intel Supported configuration Devices --> Intel supported Third party configuration device):

I hope this will help you.

Thanks. :)
