3.8 TROUBLESHOOTING

Debug Connection Problems

While using the starter kit as a debugger, you may get the error “Unable to Enter Debug

Mode” when programming the device. This can result from communication being lost

between the starter kit and MPLAB IDE. To resolve this:

1. Unplug the USB cable from the starter kit.

2. Plug the USB cable back into the starter kit.

MPLAB IDE should automatically reconnect to the starter kit. If this does not work, do

the following:

1. Check the USB connection between the PC and starter kit at both ends.

2. If using a USB hub, make sure it is powered.

3. Make sure the USB port is not in use by another device.

Programming Problems

If during the course of developing your own application you can no longer program the

device on the starter kit, you may have set device configuration bits to code protect or

some other state that prevents programming. To view the settings of the configuration

bits, select Configure>Configuration Bits

3.9 SETTINGS DIALOG, INFO TAB

When you select Debugger>Settings or Programmer Settings, you will open the Starter

Kit Settings dialog.

Currently, there is only one (Info) tab on this dialog, displaying the following

information:

• Firmware Version: The version of firmware on the starter kit board.

• Debug Exec Version: The version of the debug executive that is loaded into the

dsPIC33F device program memory to enable debug operation.
