    Things to note about the final .rpd that worked

    • Little Endian
    • Bit Reversal handled in embedded code
    • Generated pointing to EPCQ128 in the 'Convert Programming File' tool
    • Active Serial (not x4, just normal)

Any thoughts on this?

I've tried every file type I know how, still with no luck.

  • I made sure to generate the .rpd file using a version of Quartus that supports EPCQ128A
  • I've tried both big and small endian versions of the above .rpd file
  • I made sure to bit swap every byte before writing it to flash memory
  • I can write and read back the memory contents of EPCQ128A accurately (aka confirmed data is getting written properly)
