    Change EPCS64 from S25FL164K to S25FL064L

      We use the EPCS64 Flash (S25FL164K) for configure Altera FPGA before, we generate the .jic file and can download the .jic file successfully. (AS mode)
      Now we want to change this flash chip to S25FL064L. I read the datasheet, they have the same pins and we only use the serial mode(single-bit).
      The circuit is all same with before. But the .jic file cannot download successfully, the problem shows in quartus is “Error (209025): Can't recognize silicon ID for device 1”.
      I don’t know the reason for this problem, is any difference between using method of these two chips? or I need to do some different settings when generate .jic files?
      Thanks in advance.
