Test Procedure
7.1 EVM Wakeup
For the first time, the MSP430 firmware must be flashed as follows:
1. Set jumper configuration as described in
2. Plug the USB cable into the PC to flash the MSP430 on the board.
3. Load the MSP flash tool on the PC.
4. Click on MSP430 firmware upgrade utility.
5. Click the Next button.
6. Plug the USB cable into the connector on the board.
(a) Press the browse button then select USB2ANY and hit open
(b) The Upgrade button should be highlighted
7. Press the Upgrade button.
8. Wait for the MSP430 to be flashed.
9. Close the tool, then disconnect and reconnect the USB cable. The LED should blink three times then
stay on.
10. If a voltage source is used instead of a battery, the source must be able to sink some current.
7.2 Set Input Voltage
With the input supply off or disconnected from the unit under test, adjust the input voltage to 3.8 V. For the
supply connections, see
Input Supply
. Ensure that the input power supply current limit is set
at 2 A.
7.3 Enable DUT
With the power supply connected to the input pins, turn on the power supply.
To power up the UUT, press the POWERON pin for 1 second. Check the following power outputs on the
EVM to check if the UUT powered on properly.
