MCX-N9XX-EVK Board User Manual
2.16 Board errata
• Incorrect device type - Boards with devices marked "PMCXN947" may report an incorrect device type in the
SYSCON->DEVICE_TYPE field.
• Erroneous HVD assertion - Boards with devices marked "PMCXN947" may assert HVD events if VDD is
greater than 3.5 V. This applies only to configurations that supply VDD externally.
• EdgeLock 2GO service not provisioned - Boards with devices marked "PMCXN947" do not have the proper
provisioning for the EdgeLock 2GO service. If this service is required, contact your local field applications
engineer (FAE) or sales representative for assistance.
• Wakeup times may be faster than expected - Boards with devices marked "PMCXN947" may exhibit faster
wakeup times than qualified "MCXN947" devices.
• Incorrect LDO_SYS output capacitance - Boards with devices marked "PMCXN947" do not have the required
0.9 µF - 2.1 µF of capacitance. As a result, a false HVD / LVD event may occur. No other functional impacts
are known.
2.17 Board operating conditions
The operating temperature range for the MCX-N9XX-EVK board is -40
℃
to +105
℃.
The MCX N94x device
supports up to 105
℃.
See MCX N94x, N54x Product Family Data Sheet for more details on device operating
conditions.
3 MCU-Link OB debug probe
This section describes the MCU-Link onboard (OB) debug probe, its features, how to install software support for
it, and how to update its firmware.
3.1 MCU-Link overview
MCU-Link is a debug probe architecture jointly developed by NXP and Embedded Artists. The MCU-Link
architecture is based on the LPC55S69 MCU, which is based on the Arm Cortex-M33 core.
The MCU-Link architecture is configurable to support different debug feature options, and to support both
standalone probes (such as MCU-Link Pro) and for use on-board evaluation boards such as MCX-N9XX-EVK.
These on-board implementations are referred to as MCU-Link OB.
The MCX-N9XX-EVK board implements a subset of the MCU-Link architecture features, as described in
Section 3.2. For more information on MCU-Link visit MCU-Link Debug Probe Architecture.
The MCU-Link OB on the MCX-N9XX-EVK board is factory programmed with the firmware based on the NXP
CMSIS-DAP protocol. The firmware also supports all other features supported in the hardware. A custom
version of the J-Link firmware to make MCU-Link OB compatible with J-Link LITE is also available. However,
this firmware version supports only limited features, including debug/SWO and VCOM. For information on how
to update the firmware, see Section 3.5.
3.2 Supported MCU-Link features
MCU-Link includes several mandatory and optional features. Table 31 summarizes the MCU-Link features
supported on the MCX-N9XX-EVK board.
Feature Description
Serial wire debug (SWD) / serial wire debug
trace output (SWO)
Allows SWD-based debugging with SWO for profiling and/or low
overhead debug standard I/O communication
