UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards NOTE: if the Debug Probe is set up to boot in DFU mode, the USB bridge functions (virtual COM port) and Debug Probe features will not be available if the board is not first initialized by the MCUXpresso IDE. -
Page 11: Starting A Debug Session Using An External Debug Probe
UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards When the board is used for the first time, it is recommended to force the target into known state by performing an ISP boot before attempting to run your first example code. This can be achieved by pressing and holding down the ISP button while pressing and releasing the reset button. -

UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards 4. On-board (Link2) Debug probe This section describes the features provided by the on-board Link2 Debug Probe, including how to use this to debug an exernal target. The Link2 Debug Probe is implemented using an LPC432x MCU (circuit reference U16), which provides a high speed USB port interface to the host computer that runs the development tools. -

UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards 4.1 Link2 boot LED LED D8 is the Link2 MCU BOOT0_LED indicator. This LED reflects the state of Link2 MCU pin P1_1. When the boot process fails, D8 will toggle at a 1 Hz rate for 60 seconds. -
Page 14: Board Power
UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards 5. Board Power The LPCXpresso55S16 board requires +5V input to power the on-board voltage low dropout linear regulators, of which there are 3, circuit reference U1, U3 and U4. . The Link2 Debug probe has a 2.5V regulator (U1) which draws power from USB connector J1 ("Debug Link") only. -

UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards used to connect power from a load switch to the VBUS signal of the port selected; JP2 should be placed in position 1-2 for USB0 or position 2-3 for USB1. If neither USB port is being used as a USB host this jumper is not required. -
Page 16: Can-Fd Connector
UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards 7.2 CAN-FD Connector The LPC55S16 MCU includes a CAN-FD controller. On LPCXpresso55S16 board, P1.22 (IOCON Function 9) and P1.27 (IOCON Function 9) are configured as CAN_RXD and CAN_TXD respectively. A CAN-FD transceiver, U9, TJA1044, is populated on the board with level shifters between LPC55S16 target and CAN-FD transceiver to support both 1.8V and 3.3V. -
Page 17: User (Sw3) And Wakeup (Sw1) Buttons
UM11158 NXP Semiconductors LPCXpresso55S16 Development Boards The ISP button can also be used in user application code. Care should be taken if P0_5 is configured as an output driving high, since pressing this button will short it to ground. Note that jumper JS3 may also be used as a convenient way to always assert ISP when the LPC55Sxx is reset or powered up. -
