6.2 Using on-board Link2 to debug an off-board target LPC MCU
The LPCXpresso54102 board
’s Link2 debug probe may be used to debug an off-board
target MCU. The on-
board Link 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 LPC54102 MCU from
interfering with the SWD interface, JP1 must be fitted. 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 LPCXpresso54102 board from the Link USB connector J6, and
jumper JP2 must be fitted across pins 2 - 3 (
External
Target), as shown in, as shown in

7. LED indicators
The LPCXpresso54102 board LED locations are shown in Figure 11. A description of
each on-board LED indicator is shown is Table 3
The current through the LEDs does
not contribute to current monitored by the current monitor methods shown in this manual.
