1. Plug It In
Let's take your EVK board for a test drive! You have the choice of watching the sequence in a short video or following the detailed actions listed below.
1.1 Get Familiar with the Board
The LPC5500 board is pre-programmed with a diagnostic demo, which tests various features of the board. This program utilizes the MCU-LINK VCOM output connected to the debug probe(J1), which acts as a serial to USB bridge to a host computer, as well as providing the CMSIS-DAP debug interface.
1.2 Install Drivers
MCU-Link is supported on host computers running on Windows 10, MacOS X and Ubuntu Linux operating systems (OSs). For each OS, 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 options.
To download and install the host device drivers and update the MCU-Link firmware, follow these steps:
- Go to the MCU-Link board page on the NXP website
- Click Design Resources. Then, click Development Software under SOFTWARE category. Installation packages are displayed for all three OSs
- Download the package for your host OS and install it (Linux / MacOS) or execute the installer program (Windows). The package is installed/unzipped to the MCU-LINK_installer_Vx_xxx directory
- Switch MCU-Link to (USB) ISP mode by shorting jumper
JP25 - Connect the
J1connector on the board to the USB port of the host computer through a USB micro-B cable. MCU-Link gets powered up in (USB) ISP mode. The red MCU-Link status LED (D16) lights up. The board gets enumerated as a human interface device (HID) class device - 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 option
- Disconnect the board from the host computer, remove jumper
JP25and reconnect the board
1.3 Serial Terminal
Most of the MCUXpresso SDK examples and this out-of-box demo set up for MCUXpresso IDE, IAR and Keil tools use the MCU UART for print output. If you are not sure how to use a terminal application, try one of these tutorials: MCUXpresso Terminal Tutorial, Tera Term Tutorial, PuTTY Tutorial.
1.4 Plug in the Board
Connect a micro USB cable from connector J1 to a host computer or power supply to power up the board and run the demo program. Open a terminal emulator program (such as Teraterm or PuTTY), and look for a port with a name of the form “COMxx MCU-LINK VCOM ...”, and connect to it. Set the serial port for 115200 baud rate, 8 bits, no parity.
1.5 Run the Out-of-Box Demo
- The RED user LED will flash 3 times, then the green LED will flash 3 times and finally the BLUE led will also flash three times
- The terminal will display the LED sequence that is shown in addition to the RTC starting time that was set
- Press the SW1 button and the RED led will turn on. If you press the SW3 button then the GREEN led will turn on instead
- The terminal will also print “Connect USB cable to
J3for mouse application test”. Connect another micro USB cable toJ3in order to enumerate the mouse device USB application. This will cause your mouse pointer to have a square movement.
