Zigbee JTAG

The Interposer board contains a dedicated Zigbee JTAG connector. This connector is used only for debug of the on-

board Zigbee controller in case the Flashing of firmware to the controller is required. As such, this connector cannot

be used for system debug.

Reset Pushbutton Switch

Reset of the ARTIK module is accomplished by depressing the RESET button located on the Interposer board. This

button is located near the RJ45 Ethernet jack right next to the PWR_KEY button shown in Figure 3. The button is

indicated as RESET on the silkscreen. When this button is depressed, the entire development platform is reset,

except for the power controller (PMIC) on the ARTIK module, and all data is lost.

The PWR_KEY pushbutton switch located on the Interposer board performs the following functions:

•

System Power Up: Pressing and holding the PWR_KEY button until the red LED illuminates causes the system

to power-up the board.

•

System Power Down: Pressing and holding the PWR_KEY button until the red LED goes off causes the system

to turn off.

The location of the PWR_KEY pushbutton switch is shown in Figure 9.

The Interposer board also contains a 4-pin jumper (JP400) that allows the system to boot automatically once power

is applied, effectively bypassing the PWR_KEY button by grounding the AP_PWRKEY pin on the ARTIK module. This

jumper is located right next to the Reset button as shown on the Interposer board in Figure 9. When pins 1 and 3 of

this jumper are connected, the PWR_KEY LED turns on and boot-up commences once power is applied to the board.

When this jumper is inserted, pressing and holding the PWR_KEY button as described above is not required. Note

that pins 2 and 4 of this jumper are used for Zigbee JTAG and are not used for PWR_KEY purposes.
