I am trying to configure EP2AGX Arria® II GX using EPM240 Max ii CPLD and on board CFI Flash js28f256m29ewh using PFL IP.

In my case our custom Board flash Address bus 24bit bus and Data 8bit Bus from FPGA conected as per PFL requirement

but in case of CPLD only connected with 24bit Addresses to Flash and Data bus is not contected between CPLD and CFI Flash

my question is
1.how configure PFL for CFI flash program from CPLD ?

2.can i program by using PFL from FPGA ?

What will the best option for me please help us.

      Hi

      Sir

      Thanks for your reply

      In my case I wrote my above post our custom board doesn't have directly CPLD to CFI data port there

      thats why I am confused how to define PFL_flash_data [0] to PFL_flash_data[7] in PFL? CFI flash D15 also connected with CPLD.

      PFL_flash_addr[0] to PFL_flash_addr[24] CPLD to CFI connected there

      all require another pin connected between CPLD and CFI Flash like nce,we,oe etc

      Thanks

    Hi Nome,


    No connection is needed between Arria II and flash, this is because it will be control by PFL and CPLD(Max 10) to load in Arria II.


    Regards,

    Aiman

      Hello
      Thanks for your reply
      sir i am not talking about connection between Arria fpga and flash.
      I am talking about data bus between cpld max II and flash
      if we doesn't have physically data bus between Max II and flash how pfl will work?
      Thanks
