    After registration, I received CPLD firmware (MCF547X__64.upd) from Logicpd. I downloaded it with the “update” command in Lolo; after that, if I press S3 button, the line IRQ6# will come back to 0 (correct behavior).

    The problem is that if I reset the system (S1 button or switch off and then switch on), the S3 button will not have effect on IRQ6# line (monitored on pin 44 of J12 with an oscilloscope).

    My questions are:
    - Have I to program CPLD after each power on or reset? For me this is not possible because of on my project I do not use Lolo.
    - Is there any procedure in order to activate CPLD firmware? I suppose the firmware is on the CPLD but it is not active.


    Thanks in advance

    The error you are seeing is probably due to a revision change to the Xilinx CPLD IC on the board. A new .upd file needs to be generated for the update to work correctly. This process has been started and a new .upd file should be available in the near future. Sorry for any inconvenience.
