The microchip device is in most of the case delivered with a 0.9.5 a version 1 seems to be available even if not downloadable from microchip product webpage.

Main problem I found with the tool: it is not possible on a MAC to open the firmware file to load. Other functions are accessible. On W7 it is possible to flash the device :


  • Connect the device with bootloader mode check activated
  • Select the firmware hex file
  • Select 19200 bps as for speed
  • Clic … sometime it is short (and not working) sometime it is longer and working
