NXP Semiconductors MCX-N9 EVK Series - Supported Debug Scenarios

NXP Semiconductors
UM12036
MCX-N9XX-EVK Board User Manual
Feature Description
Virtual communication (VCOM) serial port Adds a serial COM port on the host computer, and connects it to the
target MCU by using MCU-Link as a USB-to-UART bridge
USB serial input/output (USBSIO
[1]
Adds a USB serial I/O port on the host computer, and connects it to the
target MCU by using MCU-Link as a USB-to-SPI bridge or USB-to-I2C
bridge
External debug probe support Allows debugging the target MCU (MCX N94X) using an external debug
probe, instead of MCU-Link. Support for an external debug probe is
enabled by disabling the SWD feature. While using an external debug
probe, the VCOM and USBSIO features can be used.
External target support
[1]
Allows debugging an external target MCU using MCU-Link
Energy/power/current/voltage consumption
measurement
[1]
(MCUXpresso IDE only)
Allows onboard measurement of current drawn by the target MCU

[1] J-Link firmware does not support this feature.)
3.3 Supported debug scenarios
In the MCX-N9XX-EVK board, the MCU-Link debug probe target can be either the MCX N94X MCU or an
external target compliant with MCU-Link. The board also allows to use an external debugger for debugging the
MCX N94X MCU, in place of the MCU-Link debug probe.
Table 32 describes the debug scenarios supported on the MCX-N9XX-EVK board.
