      As you probably know, KVASD is a soft-decision decoder for the Reed
      Solomon (63,12) code using six-bit symbols. It uses a petented
      algorithm (see the note at bottom of this WSJT web page

      In principle there's no reason it could not be compiled for the ARM
      processor. Evidently there is not much demand; I have never before seen
      such a request. I do not have an ARM-based machine on which to do the
      compile. It's not clear that the Raspberry Pi has enough "horsepower"
      to make it a useful platform for the JT65 mode.
