System powerup and operation
Before continuing, check the following:
• The Host and Meter sample projects are compiled, edited, and programed.
• The board assembly steps are completed.
• The Ethernet LAN cable is connected to the i.MX RT106x EVK.
• Any power sources are disconnected from the boards.
Make sure that your router or network does not reject the internet connection for the i.MX RT106x.
NOTE
8.1 Power up
It is important to perform the following steps in a sequential order to power up:
1. Apply power to the i.MX RT106x evaluation board and you should see the on-board green LED on and the LCD
backlight on. Power can be provided directly from the board debug port connector J41. If necessary, see the EVK user
guide for any other power sourcing options.
2. Apply power to TWR3x via a USB cable.
This order is essential in this simple interconnect scheme. The i.MX RT106x evaluation board can fail to start
if it has power applied to its IOs before receiving the main power to the chip. In a real system, use isolation. It
completely removes this issue.
NOTE
8.2 Boot
1. Verify that the TWR-KM3x board LCD is on and displays characters.
2. In the serial terminal, check that the EasyEVSE boot messages show a successful connection to the Azure IoT Central
and that telemetry is being sent. See
Verify connection of device with Iot central application
.
3. When the EVSE boots as expected, go to your Azure IoT Central application and migrate the device to the EasyEVSE
Migrate device to the EasyEVSE dashboard
4. Navigate to the EasyEVSE Dashboard view.
