external debug probe, instead of the on-board debug probe, the Link USB connector
(J15) must be disconnected.
The JN5189 Target VBAT selection is made at JP3, J5, with 3.3V from on-board LDO set
as the default.
2.9 Debug Configurations
The DK6 board has a built-
in debug probe referred to as “Link2”. The JN5189 target
wireless MCU can be debugged by the Link2 debugging probe, or from an external
debug probe installed at P1. On-board jumpers JP1 and JP2 must be correctly positioned
for each mode. The on-
board Link2 debug probe is capable of debugging target MCU’s
with a VDDIO range of 1.6V to 3.6V. Check the sections below for the appropriate jumper
settings and how to properly power the board.
2.9.1 Debug using on-board debug probe
To use the on-board Link debug probe:
•
The jumper JP2 must be fitted in position pin 1 - 2 (Local Target).
•
Jumper JP1 must be open or fitted in position 2
– 3 to enable the target
JN5189.
•
Connecting the mini USB J15 to a host computer will power the Link and
according JP3, J5 position, the JN5189 sections of the board and provide
the USB link to the debug tool software.
2.9.2 Debug using external debug probe
To use an external debug probe:
•
connect the probe to the SWD (P1) connector
•
power the JN5189 Target section of the board from the FTDI header (J1) or
