Is there a known problem with the Intel® MAX® 10 FPGA On Chip Flash IP for UFM read operations?

Environment

  • Quartus® II Software
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    Due to a known problem in the Intel® Quartus® Prime Software, data read failures might occur when using the On Chip Flash IP to read User Flash Memory (UFM) in Intel® MAX® 10 devices.

    Resolution

    To work around this, modify the altera_onchip_flash_avmm_data_controller.v file as shown below. This file can be found in the following location <Quartus installation folder>\ip\altera\altera_onchip_flash\altera_onchip_flash\altera_onchip_flash_avmm_data_controller.v

    Original:

         assign flash_read_addr = (is_read_busy) ? flash_seq_read_ardin : avmm_addr;

    Modified:

         assign flash_read_addr = avmm_addr; // (is_read_busy) ? flash_seq_read_ardin : avmm_addr;

     This problem will be fixed in a future version of the Intel® Quartus® Prime Software.
