MCU-Link OB debug probe

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. The architecture is used both in standalone debug probes (such as MCU-Link Pro) and for onboard debug probes in evaluation boards (such as FRDM- MCXA153). The onboard implementation of MCU-Link is referred to as MCU-Link OB.
The FRDM-MCXA153 board implements a subset of the MCU-Link architecture features, as mentioned in Section 3.1. For more details on the MCU-Link architecture, visit the MCU-Link Debug Probe Architecture page.
The MCU-Link OB on the FRDM-MCXA153 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 3.4.

Supported MCU-Link features
MCU-Link includes several mandatory and optional features. Table 15 summarizes the MCU-Link features supported on the FRDM-MCXA153 board.
Table 15. Supported MCU-Link features

allows SWD-based debugging with SWO for profiling and/or low overhead debug standard I/O communication.
Virtual communication (VCOM) serial port| MCU-Link adds a serial COM port on the host computer and connects it to the target MCU while working as a USB-to- UART bridge.
External debug probe support| The MCU-Link interface supports debugging the target MCU (MCXA1xx) using an external debug probe, instead of MCU-Link. Support for an external debug probe is enabled by disabling the SWD feature.
External target support[1]| MCU-Link can also be used to debug an external target.
[1] J-Link firmware does not support this feature.

MCU-Link host driver and utility installation
The MCU-Link debug probe is supported on Windows 10/11, MacOS X, and Ubuntu Linux platforms. It uses standard OS drivers. For Windows, the installation program also includes information files to provide user-friendly device names.
Support for MCU-Link can be enabled using the Linkserver utility, which is an NXP GDB server and flash utility that supports many NXP debug probes. Running the Linkserver installer also installs all the drivers and a firmware update utility required for MCU-Link.
NXP recommends you to use the Linkserver utility for installing the MCU-Link drivers and firmware update utility, unless you are using MCUXpresso IDE version 11.6.1 or earlier. For more details on this utility, visit the https://nxp.com/linkserver page.
Note: Installing the Linkserver utility (using the Linkserver installer) only installs the device drivers required for MCU-Link, it does not update the MCU- Link firmware. The Linkserver installation package includes the utilities that are used to update the firmware. If you are using MCUXpresso IDE version 11.6.1 or earlier, you must install the firmware update utility version 2.263, which is not included in the Linkserver installation package.

If you cannot use the Linkserver utility, follow these steps to install the MCU-Link drivers and firmware update utility

1. Visit the board page on the NXP website (not available yet).
2. Go to the Design Resources > Software section. Under the Development Software category, MCU-Link installation packages for Windows, MacOS, and Linux platforms are available.
3. Download the MCU-Link installation package applicable to your host OS.
4. Run the installer program (for Windows) or install the firmware package (for MacOS or Linux).

You are recommended to update the MCU-Link firmware on your board to the latest firmware version to get the latest functionality. Steps to update the firmware are provided in Section 3.4. Before updating the firmware, check if the MCU-Link firmware you want to use is compatible with the MCUXpresso IDE installed on your host computer (see Table 17).

Table 17. Compatibility between MCU-Link firmware and MCUXpresso IDE

MCU-Link firmware version| USB driver type| CMSIS-SWO

support

| FreeMASTER support via| Supported MCUXpresso IDE versions
---|---|---|---|---
SWD / JTAG| USB bridge
V1.xxx and V2.xxx| HID| No| Yes| Yes| MCUXpresso 11.3 or later
V3.xxx (up to and including V3.108)| WinUSB| No| Yes| FreeMASTER V3.2.2

or later

| MCUXpresso 11.7.0 or later
V3.117 and later| WinUSB| Yes| Yes| FreeMASTER V3.2.2

or later

| MCUXpresso 11.7.1 or later

Updating MCU-Link firmware
When updating the MCU-Link firmware, MCU-Link must be powered up in ISP mode. To configure MCU-Link in ISP mode and update MCU-Link firmware, follow these steps:

1. Disconnect the board from the host computer, short jumper JP8, and reconnect the board. The red MCU-Link status LED D7 lights up and stays on. For more details on MCU-Link LEDs, see Section 3.8.
2. Navigate to the MCU-LINK_installer_Vx_xxx directory, where Vx_xxx indicates the version number, for example, V3.108.
3. Follow the instructions in the readme.txt to find and run the firmware update utility for CMSIS-DAP or J-Link firmware version.
4. Disconnect the board from the host computer, open jumper JP8, and reconnect the board. The board enumerates on the host computer as a WinUSB or HID device (depending on the firmware version).

Note

•  Starting version V3.xxx, the MCU-Link firmware uses WinUSB instead of HID for higher performance. However, it requires MCUXpresso IDE version 11.7.0 or higher.
• MCU-Link firmware versions starting V3.117 provide CMSIS-SWO support, which means they can enable SWO-related features in non-NXP IDEs.

Using MCU-Link with development tools
The MCU-Link debug probe can be used with IDEs supported within the MCUXpresso ecosystem, such as MCUXpresso IDE, MCUXpresso for Visual Studio Code, IAR Embedded Workbench, and Arm Keil MDK.

Using MCU-Link with MCUXpresso IDE
The MCUXpresso IDE recognizes any type of MCU-Link probe that uses either CMSIS-DAP or J-Link firmware. When you start a new debug session, the IDE checks for all the available debug probes. For all the probes it finds, the IDE displays the probe types and unique identifiers in the Probes discovered dialog box.
If a debug probe requires a firmware update, the probe is displayed with a warning in the Probes discovered dialog box. For each such probe, the latest firmware version is indicated and a link to download the latest firmware package is provided. To update the firmware for the MCU-Link debug probe, see the instructions provided in Section 3.4.
You are advised to use the latest MCU-Link firmware to take the benefit of the latest functionality. However, the MCU-Link firmware version you can use depends on the MCUXpresso IDE installed on your host computer. To check the compatibility of the MCU-Link firmware you want to use with your MCUXpresso IDE, see Table 17.

Using MCU-Link with MCUXpresso for Visual Studio Code
The MCU-Link debug probe can be used with the MCUXpresso for Visual Studio Code extension from NXP. This extension uses the Linkserver debug server. To work with MCUXpresso for Visual Studio Code, install the Linkserver utility using the MCUXpresso Installer tool or as described in Section 3.3. For more details on MCUXpresso for Visual Studio Code, visit the MCUXpresso for Visual Studio Code page.

Using MCU-Link with third-party IDEs
The MCU-Link debug probe can be used with IAR Embedded Workbench and Arm Keil MDK, and may also work with other third-party tools. Refer to the documentation for these products, covering the use of generic CMSIS-DAP probes or J-Link probes (depending on the firmware image you are using).

MCU-Link USB connector
The FRDM-MCXA153 board has a USB Type-C connector J15, which allows you to connect MCU-Link with your host computer. It can also be used to supply 5 V power to the board.

VCOM port (USB to target UART bridge)
MCU-Link supports the VCOM serial port feature, which adds a serial COM port on the host computer and connects it to the target MCU while working as a USB- to-UART bridge.
In the FRDM-MCXA153 board, MCU-Link is connected to the LPUART0 port of the target MCU. To use MCU-Link as a USB-to-UART bridge, verify the following jumper settings and connect the J15 connector on the board to the USB port of the host computer:

• Jumper JP8 is open (MCU-Link boots normally)
• Jumper JP19 is open (MCU-Link VCOM port is enabled)

When you boot the FRDM-MCXA153 board, a VCOM port with the name MCU-Link Vcom Port (COMxx) is enumerated on the host computer, where “xx” may vary from one computer to another. Each MCU-Link based board has a unique VCOM number associated with it.
The VCOM function can be disabled by shorting jumper JP19, before powering up the board. Changing the jumper JP19 setting (open/short) after powering up the board has no impact on the VCOM function in terms of how MCU-Link behaves.

MCU-Link status LEDs
The FRDM-MCXA153 board has seven status indicator LEDs for MCU-Link. Table 18 lists these LEDs and describes how each LED behaves in different MCU-Link modes.

Table 18. MCU-Link LEDs

ISP (firmware update) mode
D5| USB_ACTIVE| Green| Indicates USB communication. The LED lights up after successful USB enumeration at startup, and then stays ON.| The LED remains OFF.| The LED remains OFF.
D7| ISP_EN| Red| Indicates MCU-Link status / SWD activity. It blinks rapidly at startup, if an error occurs.

The LED acts as a heartbeat LED (fades in/ out repeatedly), with SWD activity overlaid.

| The LED remains OFF.| The LED lights up when MCU-Link (LPC55S69) boots in ISP mode.
D8| VCOM_ACTIVE| Green| Indicates if the VCOM port is receiving/sending data. The LED lights up when MCU-Link boots, and then blinks when debug activity happens.| Indicates if the VCOM port is receiving/ sending data. The LED lights up when MCU- Link boots, and then blinks when debug activity happens.| The LED remains OFF.
