•
The on-board Link2 debug probe must be unpowered, by leaving USB mini
(J15) unconnected.
2.9.3 On-Board Link2 flash programming
To program the Link2 Flash the Link2 MCU must be in DFU mode. If the Link2 already
has a valid image in the flash, you will need to force it into DFU mode by placing a
jumper shunt on JP5 across pin 1 - 2, then power the board by connecting the mini USB
J15 to a host computer. Link2 MCU programming is performed using the LPCScrypt
https://www.nxp.com/design/microcontrollers-developer-resources/lpc-
microcontroller-utilities:LPC-UTILITIES
). Instructions for using the tool are located at the
same web page.
2.9.4 Using the DK6 to debug an off-board target
The DK6 board’s Link2 debug probe may be used to debug an off-board target MCU.
The on-
board Link2 debug probe is capable of debugging target MCU’s with a VDDIO
range of 1.6V to 3.6V. To keep the on-board target K32W061/041 MCU from interfering
with the SWD interface:
•
JP1 must be fitted across pin 1 - 2.
•
The Link2 debug probe SWD is connected by a ribbon cable between the
P1 connector to the off-board target MCU SWD interface.
•
Power the DK6 board from the Link USB connector J15,
•
Fit jumper JP2 across pins 2 - 3 (External Target).
