Some Questions to Answer First

  1. 1.What device are you working with? Often an upgrade to a newer pack (DFP/TP) version for MPLAB X IDE is required to support newer devices.
  2. 2.Are you using a Microchip demo board or one of your own design? Have you followed the guidelines for resistors/capacitors for communications connections? See Target Connections.
  3. 3.Have you powered the target? The emulator can only power the target when it is powered by an external 9V power supply. For details see Power Specifications.
  4. 4.Are you using a USB hub in your set up? Is it powered? If you continue to have problems, try using the emulator without the hub (plugged directly into the PC.)
  5. 5.Are you using a communication cable shipped with emulator? If you are using a longer cable, it may have communications errors. If a longer cable is required, consider another type of communication. See PC Connections.
  6. 6.Are you using the USB cable shipped with the debugger? Other USB cables may be of poor quality, too long or do not support USB Communication.
