Note:
Other IDEs that support CMSIS-DAP or J-Link protocol can also use the MCU-
Link debug probe; refer to the documentation for these IDEs for more information.
3.2 Installing device drivers and updating MCU-Link firmware
MCU-Link is supported on host computers running on Windows 10, MacOS X, and
Ubuntu Linux operating systems (OSs). For each of these OSs, an MCU-Link firmware
package is available that includes the host device drivers, MCU-Link firmware, and
scripts to program CMSIS-DAP and J-Link firmware. The host device drivers are included
in the firmware package to configure the host so that it displays user-friendly device
names.
To download and install the host device drivers and update the MCU-Link firmware,
follow these steps:
1. Go to the
2. Click
Design Resources
, and then click
SOFTWARE
. Installation packages for all
three OSs are displayed.
3. Download the firmware package applicable to your host OS.
4. Depending on the host OS, install the firmware package (Linux/MacOS) or execute
the installer program (Windows). The firmware package is installed/unzipped to the
MCU-LINK_installer_Vx_xxx directory (where Vx_xxx indicates the version number,
for example, V2_220). The directory has a "Readme.txt" file and few subdirectories
that contain other package components, including host device drivers, MCU-Link
firmware, and scripts to program CMSIS-DAP and J-Link firmware.
Host drivers are usually installed automatically during firmware package installation.
In case you need to install the drivers manually, refer to the "Host Configuration"
section of the "Readme.txt" file.
Before powering up the board for updating MCU-Link firmware, you must switch
MCU-Link to ISP mode (USB1).
5. To force MCU-Link to boot in ISP mode (USB1), short jumper JP25.
6. Connect the J1 connector on the board to the USB port of the host computer through
a USB micro-B cable. MCU-Link gets powered up in ISP mode (USB1). The red
MCU-Link status LED (D16) lights up (for more details on MCU-Link LEDs, see
). The board gets enumerated as a human interface device (HID) class
device.
7. Program the MCU-Link firmware into the MCU-Link internal flash using the
instructions provided in the "Firmware Installation Guide" section of the "Readme.txt"
file. Use the scripts provided to program the CMSIS-DAP or J-Link firmware.
8. Disconnect the board from the host computer, remove jumper JP25, and reconnect
the board.
Now, the system behaves differently based on whether the CMSIS-DAP or J-Link
firmware was programmed:
•
If the CMSIS-DAP firmware was programmed, then the red status LED (D16) fades
in/out repeatedly (“breathing”), while the green USB status LED (D14) stays ON
constantly. In this case, four devices (three HID devices and one VCOM port) get
enumerated, as shown in the figure below.
