The graphic below gives an overview of the board features and the connection between the target MCU and the on-board components and connectors

Board Pinout¶

Arduino and NXP Header Pinout¶

Board headers enable up to 32-pins and give access, deliver right signals to meet Arduino R3 standard

The IMXRT1050-EVKB is fully supported in the mbed platform, so it gets access to the free tools and SDK that provides experienced embedded developers with powerful and productive tools for building proof-of-concepts.

PC Configuration¶

Your mbed Microcontroller can appear on your computer as a serial port. On Mac and Linux, this will happen by default. For Windows, you need to install a driver:

From a host PC to communicate with mbed you will need a terminal application. This allows the mbed Microcontroller to print to your PC screen, and for you to send characters back to your mbed.

• Terminals - Using Terminal applications to communicate between the Host PC and the mbed Micrcontroller

Some terminal programs (e.g. TeraTerm) list the available serial ports by name. However, if you do need to know the identity of the serial port so that you can attach a terminal or an application to it:

	'''Windows'''		'''Mac'''		'''Linux'''
	Find the identity of the COM port by opening ''Device Manager''. To do this navigate ''Start -> Control Panel -> System -> Hardware -> Device Manager''.		To find the device name under Mac OS X, use the command ''ls /dev/tty.usbmodem*''		To find the device name under Linux, use the command ''ls /dev/ttyACM*''

Firmware Update¶

Get Started with mbed¶

First board connection¶

Use the USB lead to connect your mbed to a PC. The status light will come on, indicating it has power. After a few seconds of activity, the PC will recognize the mbed Microcontroller as a standard USB drive.

Flash a project binary¶

1. Download a (.bin) to the EVK¶

Download the appropriate "Hello World!" binary:

• IMXRT1050-EVKB: mbed-os-example-blinky.mimxrt1050_evk.bin

Note: the source code for this program will be seen in the next section.

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

2. Press the Reset Button¶

When the Reset Button in pressed, the newest program on the mbed Microcontroller Disk will be loaded in to the Microcontroller FLASH memory. The Status LED will flash as this happens.

When the program is has been loaded onto the microcontroller, it will then start it running.

3. Run Hello World!¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.

4. Flash a new precompiled program¶

It is the newest program on the mbed Microcontroller that is run after reset. We can therefore download a new program or overwrite an existing one to update the program that will run.

Open existing Project¶

1. Import the Program to your mbed compiler¶

Select Import As Program
Choose Import Name of your preference
Click on Import

[Repository '/teams/mbed-os-examples/code/mbed-os-example-blinky/' not found]

2. Compile the Program¶

In the right panel Program Workspace Select the program you want to compile
Click on Compile in toolbar
If compilation ends successfully, you should see the comment Success! displayed in the Compile Output window available in the bottom and your web browser should download automatically the precompiled binary for the program.

3. Download a (.bin) to the EVK¶

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

4. Press the Reset Button¶

When the Reset Button in pressed, the newest program on the mbed Microcontroller Disk will be loaded in to the Microcontroller FLASH memory. The Status LED will flash as this happens.

When the program is has been loaded onto the microcontroller, it will then start it running.

5. Run the Program¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.
