Why does JAM programming of a QSPI flash device fail when connected to an Intel® Stratix® 10 FPGA and when using the Intel® Quartus® Prime Pro Edition Software version 20.4 and later?

Environment

  • Intel® Quartus® Prime Pro Edition
  • Intel® Quartus® Prime Pro Edition Programmer and Tools
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 20.4 and later, errors may occur when programming a .jam (JAM) file to a QSPI flash device attached to an Intel® Stratix® 10 FPGA at high JTAG clock frequencies.

     

    Resolution

    To work around this problem in the Intel® Quartus® Prime Pro Edition Software v20.4 or later, reduce the JTAG clock frequency to 6 MHz.

     

    You can modify the JTAG TCK frequency of an Intel FPGA Download Cable II with the following command: 

     

    > jtagconfig --setparam <cable_number> JtagClock 6M

     

    This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.4.
