LPCXpresso55S69 Development Board

J4

Link2 (LPC43xx) force DFU boot.
Leave this jumper open (default) for Link2 to follow the normal boot 
sequence. The Link2 will boot from internal flash if image is found 
there. With the internal flash erased the Link2 normal boot sequence 
will fall through to DFU boot.
Install this jumper to force the Link2 to DFU boot mode. Use this setting 
to reprogram the Link2 internal flash with a new image (using the 
LPCScrypt utility) or to use the MCUXpresso IDE with CMSIS-DAP 
protocol.

Note that the Link2 flash is pre-programmed with a version of 
CMSIS-DAP firmware by default.

Open

J5

Target processor selection for the on-board Debug Probe. 
Jumper open (default) the LPC55S69 Target SWD interface enabled. 
Normal operating mode where the Target SWD is connected to either 
the on-board Link2 Debug Probe or an external Debug Probe.
Jumper shunted, the LPC55S69 Target SWD interface is disabled. Use 
this setting only when the on-board Link2 Debug Probe is used to 
debug an off-board target MCU.

Not installed

J6

USB host Vbus selection
Note that only one of USB0 or USB1 can be configured as a USB host 
port at any given time (this is a board restriction, not a limitation of the 
LPC55S69.)
Install jumper in position 1-2 for USB1 (High Speed) to provide Vbus 
(i.e. enable USB host capability) (Default)
Install jumper in position 2-3 for USB0 (Full Speed) to provide Vbus (i.e. 
enable USB host capability)

1-2 (USB1)

J7

USB host power control selection
This jumper selects routing of USB port power and overcurrent detect 
from either the USB0 or USB1 ports of the LPC55S69. Note that only 
one of USB0 or USB1 can be configured as a USB host port at any 
given time (this is a board restriction, not a limitation of the LPC55S69.)
Leave open when using USB1 (High Speed) as a USB host (Default)
Install jumper for USB0 (Full Speed) to provide Vbus (i.e. enable USB 
host capability)

Installed 
(USB1)

J10

ISP boot jumper for LPC55S69. Installing this jumper ties port P0_5 to 
ground, forcing the LPC55S69 into ISP mode whenever it is reset.

Open

n/a

J11

USB1 ID selection: USB1 ID is normally pulled to ground through a 
100Kohm resistor. Installing this jumper connects USB1 ID to VBUS.

Open

J12

USB0 ID selection: USB1 IDis normally pulled to ground through a 
100Kohm resistor. Installing this jumper connects USB0 ID to VBUS.

Open

P1

When open (default), the "Bridge" UART and SPI connections from the 
Link2 probe are driven to the LPC55S69 target. 
Install P1 when using the SPI interface at connector P20 and/or FC0 
UART at P8. Note that this disables the Link2 SPI and UART (bridge) 
connections.
