Serial communication
EVK-IRIS-W1 provides two options for serial communication and debugging:
•
MCU-Link (default) chip
•
FTDI chip
3.5.1
MCU-Link
The MCU-Link is a powerful and cost-effective debug a that seamlessly integrates with the
MCUXpresso Integrated Developer Environment (IDE). It is also compatible with third-party
IDEs that support CMSIS-DAP protocol. The USB3 MCU-Link port on the EVB
provides a USB-
to-UART bridge feature (VCOM) that can be used to provide a serial connection between the
IRIS module and a host computer. MCU-Link is based on the LPC55S69 microcontroller (
U13
)
and features a high-speed USB interface for a high-performance debugging.
The main
UART
(
UART 3 TX, RX
) and the
SWD
interface signals of the IRIS-W10 module are
connected to the MCU-Link through switches
U16
or (
R134, R136
),
U19,
or (
R142, R143
) by
default. Optional connections to the Flexcomm 0 SPI interface through switch
U18
and
resistors
R259, R260, R261, R262
, and connections to the I2C Flexcomm 2 interface through
switch
U17
, are also possible. The connection options are shown in
and further
described in

The MCU-Link JTAG/SWD Debug Probe [
], a free utility from NXP, is compatible with
Windows 10, MacOS, and Linux which provides an easy way to install firmware updates
.
