Hardware requirements

  • Mini USB cable

  • TWR-MC56F8400 board

  • Personal Computer

Board hardware common setting

  1. Power setting:

    Connect J11 pin1 and pin2 Connect J6 pin1 and J7 pin2

  2. UART setting:

    Connect J8 pin3 and pin4 Connect J9 pin3 and pin4

  3. Onboard OSJTAG debugger setting:

    Connect J20 pin1 and pin2. Leave J17 open. Note: J17 is only used(connected) when firmware update for onboard debugger OSJTAG. Connect J21 pin 1-2, 3-4, 5-6, 7-8, to setup onboard debugger OSJTAG. Note: when use external debugger(connected to J14), leave all J21 pins open

Board settings

No special settings are required.

Prepare the Demo

  1. Connect USB cable between the host PC and the JM60 USB(J18) port on the target board. It setups OSJTAG and COM port in PC device manager.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board with OSJTAG debug configuration.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

When the example runs successfully, following information can be seen on the terminal:
