  1. Great work on the programmer Jack! Already tested it on my Papilio board 🙂

    The only funny thing I found is that if I have the .bit file on a different partition (e.g. D:\…) than where the programmer is installed (C:\…), programming window immediately closes and doesn’t work. Do you have an idea what could be the cause?

    1. Ok, I did some testing and the problem stems from the cd command in the bat file. It needs a /D to tell it to change drives in addition to the directory.

      I’ll be releasing an update with a fix soon.

      In the meantime editing Papilio_Programmer.bat and replacing line 4:
      cd %0\..\bin
      cd /D %0\..\bin

      will get you up and running.
