Serial Port

The MIMXRT1170 SoC has 12 UARTs.

Programming and Debugging

The vmu_rt1170 board supports the runners and associated west commands listed below.

	flash	debug	rtt	attach	debugserver
jlink	✅ (default)	✅ (default)	✅	✅	✅
pyocd	✅	✅	✅	✅	✅

Build and flash applications as usual (see Building an Application and Run an Application for more details).

Configuring a Debug Probe

A debug probe is used for both flashing and debugging the board.

Using J-Link

Install the J-Link Debug Host Tools and make sure they are in your search path.

Connect the J-Link debugger through the debug adapter board.

Configuring a Console

Use the USB-C from the debug adapter board to access the console with the following settings for your serial terminal of choice (screen, minicom, putty, etc.):

• Speed: 115200

• Data: 8 bits

• Parity: None

• Stop bits: 1

Flashing

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b vmu_rt1170 samples/hello_world
west flash

You should see the following message in the terminal:

***** Booting Zephyr OS v3.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! vmu_rt1170

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b vmu_rt1170 samples/hello_world
west debug

Open a serial terminal, step through the application in your debugger, and you should see the following message in the terminal:

***** Booting Zephyr OS v3.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! vmu_rt1170
