A-C4CE6 Card-Features List 000.PNG

Programming the MPS16 Flash

  • This card has a single JTAG connector for code download
  • The card can be temporarily or permanently changed - but it's done with some special methods
    • Temporary programming does not persist after power cycling (or reset) (Stored in RAM
    • Permanent programming requires downloading the FPGA into the attached Serial EEPROM
  • The process to permanently program the EEPROM is more complicated
    • This is attempt to document the steps I took to make it work


Create sof file

  • In Quartus create code
  • Device: EP4CE6E22C8
  • Compile the part
    • Processing > Start Compile
  • This results in a .sof file
    • .sof file is an sram download which puts the logic into the FPGA but does not store it permanently in the EEPROM

Create jic file

  • Ap Note on this process
  • Convert .sof file to .jic file
    • jic file is a JTAG Indirect Configuration file
      • jic file is downloaded through the FPGA into the EEPROM
      • File is brought through the FPGA which will be in a soft programming mode
    • File > Convert Programming File
    • If Conversion setup was previously saved then
      • Open Conversion Setup Data...
      • Select the file
      • If via this method then the next couple of steps can be skipped
    • If this is the first time then the next few steps need to be followed
    • Programming file type: JTAG Indirect Configuration file (.jic)
    • Configuration device: EPCS16
    • Set output file name
      • Make sure path is correct since the previous path seems to persist
  • Two "segments" in the Input Files to convert section
    • Flash Loader: EP4CE6
    • SOF Data: xxx.sof
  • Verify screen looks similar to this

Conv Prog File.PNG

  • Click Generate
    • Overwrite file (if needed)
  • Save Conversion Setup so you don't need to do this next time
  • Close

Program EEPROM

  • Back in Quartus Programmer
    • In Quartus select Program Device (Open Programmer)
  • Tools | Options
    • Select Use the enhanced mode Serial Flash Loader (SFL) IP for factory default helper image
  • Autodetect device
    • EP4CE6E22 shows up in preview window below
  • Select device by clicking on it
  • Right click on device
  • Edit
    • Attach flash device
    • Select Flash Device: EPCS16 (same as MPS16)
  • Click on EPCS16 and change file
  • Select Program/Configure box and the Factory default enhanced... line will appear
  • Select Start
  • Program Device with the setup below
  • If you did this before the screen is probably already correctly filled out
  • Note this has the FPGA on the card and the serial EEPROM shown as a connection from the FPGA
    • The FPGA has "Factory default enhanced SFL image" and is assigned to the EP4CE6
    • The .jic file which was created in the previous steps is assigned to the EPCS16
  • Mode should be JTAG since the connection to the card is via the one JTAG connector
  • Select Program/configure
    • The SFL image is a soft loader which lets the FPGA control the EEPROM
      • Should be EP4CE6E22C8 part

JIC File-5-Program.PNG

  • Start
  • The FPGA is left with only the Serial programmer
  • Remove power and repower up the card to have change take effect
