Note

In order to use the SPI peripheral on this board, resistors R278, R279, R280, and R281 must be populated with zero ohm resistors

System Clock

The MIMXRT1050 SoC is configured to use SysTick as the system clock source, running at 600MHz.

When power management is enabled, the 32 KHz low frequency oscillator on the board will be used as a source for the GPT timer to generate a system clock. This clock enables lower power states, at the cost of reduced resolution

Serial Port

The MIMXRT1050 SoC has eight UARTs. LPUART1 is configured for the console, LPUART3 for the Bluetooth Host Controller Interface (BT HCI), and the remaining are not used.

USB

The RT1050 SoC has two USB OTG (USBOTG) controllers that supports both device and host functions through its micro USB connectors. Only USB device function is supported in Zephyr at the moment.

Programming and Debugging

Note

Newer revisions of this board use LPC-LINK2 Onboard Debug Probe, while older revisions use the OpenSDA Onboard Debug Probe. Schematic revisions A/A1 use the K20 OpenSDA probe, and B/B1 use the LPC-Link2 LPC4322 probe.

This board supports 3 debug host tools. Please install your preferred host tool, then follow the instructions in Configuring a Debug Probe (Schematic A/A1) or Configuring a Debug Probe (Schematic B/B1), depending on board schematic revision to configure the board appropriately.

Once the host tool and board are configured, build and flash applications as usual (see Building an Application and Run an Application for more details).

Configuring a Debug Probe (Schematic A/A1)

For the RT1050 Schematic Rev A, J32/J33 are the SWD isolation jumpers, SW4 is the reset button, and J21 is the 20 pin JTAG/SWD header.

A debug probe is used for both flashing and debugging the board. This board has an OpenSDA Onboard Debug Probe. The default firmware present on this probe is the OpenSDA DAPLink Onboard Debug Probe.

Based on the host tool installed, please use the following instructions to setup your debug probe:

Configuring a Debug Probe (Schematic B/B1)

For the RT1050 Schematic Rev B, J47/J48 are the SWD isolation jumpers, J42 is the DFU mode jumper, and J21 is the 20 pin JTAG/SWD header.

A debug probe is used for both flashing and debugging the board. This board has an LPC-LINK2 Onboard Debug Probe. The default firmware present on this probe is the LPC-Link2 DAPLink Onboard Debug Probe.

Based on the host tool installed, please use the following instructions to setup your debug probe:

Using CMSIS-DAP with LPC-Link2 Probe

  1. Follow the instructions provided at LPC-LINK2 CMSIS DAP Onboard Debug Probe to reprogram the default debug probe firmware on this board.

  2. Ensure the SWD isolation jumpers are populated

Configuring a Console

Regardless of your choice in debug probe, we will use the OpenSDA microcontroller as a usb-to-serial adapter for the serial console. Check that jumpers J30 and J31 are on (they are on by default when boards ship from the factory) to connect UART signals to the OpenSDA microcontroller.

Connect a USB cable from your PC to J28.

Use the following settings with your serial terminal of choice (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 mimxrt1050_evk samples/hello_world
west flash

Open a serial terminal, reset the board (press the SW4 button), and you should see the following message in the terminal:

***** Booting Zephyr OS v1.14.0-rc1 *****
Hello World! mimxrt1050_evk

Debugging

Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b mimxrt1050_evk 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 v1.14.0-rc1 *****
Hello World! mimxrt1050_evk

Troubleshooting

If the debug probe fails to connect with the following error, it’s possible that the boot header in HyperFlash is invalid or corrupted. The boot header is configured by CONFIG_NXP_IMXRT_BOOT_HEADER.

Remote debugging using :2331
Remote communication error.  Target disconnected.: Connection reset by peer.
"monitor" command not supported by this target.
"monitor" command not supported by this target.
You can't do that when your target is `exec'
(gdb) Could not connect to target.
Please check power, connection and settings.

You can fix it by erasing and reprogramming the HyperFlash with the following steps:

  1. Set the SW7 DIP switches to ON-ON-ON-OFF to prevent booting from HyperFlash.

  2. Reset by pressing SW4

  3. Run west debug or west flash again with a known working Zephyr application.

  4. Set the SW7 DIP switches to OFF-ON-ON-OFF to boot from HyperFlash.

  5. Reset by pressing SW4

Board Revisions

The original MIMXRT1050-EVK (rev A0) board was updated with a newer MIMXRT1050-EVKB (rev A1) board, with these major hardware differences:

  • SoC changed from MIMXRT1052DVL6A to MIMXRT1052DVL6B

  • Hardware bug fixes for: power, interfaces, and memory

  • Arduino headers included

For more details, please see the following NXP i.MXRT1050 A0 to A1 Migration Guide.

Current Zephyr build supports the new MIMXRT1050-EVKB
