13.5 MPLAB REAL ICE JTAG ADAPTOR BOARD
The MPLAB REAL ICE JTAG Adaptor (AC244007) may be used to provide JTAG
communication between the MPLAB REAL ICE in-circuit emultor and the target. The
kit contains a JTAG adaptor board, ribbon cable, and this insert.
13.5.1 JTAG Support
• The JTAG adaptor board is supported on MPLAB X IDE 1.60 and above.
• The JTAG adaptor board supports all PIC32 devices.
• Only basic debug features are available when using JTAG: Run, Halt, and Single
Step. No advanced features are available, i.e., data capture, runtime watches,
application in/out, DMA reads/writer, RTDM, and instrumented trace.
13.5.2 Switch from Standard Communications to JTAG
To switch the hardware:
1. While connected to the target using Standard Communications, erase the target
device. You may need to add “Erase Device Memory Main Project” to a toolbar
using View>Toolbars>Customize
.
2. Power down the target board.
3. Disconnect the Standard Communciations cable from the target, disconnect the
USB cable from the emulator, and unplug the Standard Driver Board from the
emulator.
4. Connect one end of the ribbon cable to the connector on the JTAG adaptor board
(it should plug in only one way) and insert the JTAG adaptor board into the
emulator driver board slot.
5. Connect the other end of the ribbon cable to the connector on a target board,
such as the Microchip Explorer 16 development board. The plug is keyed to fit
only one way.
6. Connect the USB cable to the emulator and power the target board.
To set up MPLAB X IDE for JTAG operation:
1. Select File>Project Properties
. In the Project Properties dialog, click on your
desired configuration, e.g., “Conf: [default]”.
2. Click on the down arrow on the “Supported Plugin Board” dropdown box and
select “JTAG Driver Board”. Click OK to accept the setup.
Note: The target device MUST BE ERASED before switching from Standard
Communications to JTAG communications.
