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.

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
at 2 A.
Do not exceed an input voltage of 5.5 V at any time during the testing of the
UUT.
7.3
