1.3.8. Breakout Board (TBD)
1.3.9. JTAG
You can use JTAG interface to debug MT7688AN. To access JTAG interface, you
will need to unsolder resistor R95 and solder it to resistor R3 on the
7688 development board. After you’ve moved the resistor and reboot the
device you’ll activate JTAG function. The steps are:
1) Find a group of resistors on the bottom side of LinkIt Smart
7688 (top-right view) as circled in below.

2) Next, you will move a resistor by unsoldering and soldering
it to a lower position as shown in below, after you’ve
finished moving the resistor, restart the device and you
should be able to activate JTAG function.
