3.2. Using the MCU Card with the UDP Motherboard
Refer to Figure 3 for a diagram of the hardware configuration when using the MCU card with a UDP motherboard.
1. Connect the MCU card to the UDP motherboard slot.
2. (Optional) Connect an I/O card to the UDP motherboard slot.
3. (Optional) Connect a radio test card to the radio test card slot in the UDP motherboard.
4. (Optional) Connect an EZLink card to the EZLink card slot in the UDP motherboard.
5. Connect the USB Debug Adapter to the 10-pin debug connector (J23) on the MCU card using the 10-pin
ribbon cable.
6. Connect the USB Debug Adapter to a USB Port on the PC.
7. Move the SW1 VDD Select switch to the lower MB position.
8. Verify that the JP2 Imeasure jumper is populated.
9. Connect the ac/dc power adapter to power jack J20 on the UDP motherboard. The board can also be
powered from the J16 USB, J1 mini USB connectors, or J11 battery connector socket.
10. Move the S3 power switch on the UDP motherboard to the ON position.
11. Update the motherboard firmware as described in Section 3.3.
Notes:
Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter.
Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the
ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power
can damage the device and/or the USB Debug Adapter.
The MCU card can be used alone without the motherboard. However, the motherboard must be powered if
an MCU card is connected.
