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 the 32 KHz low frequency oscillator on the board as a source for the GPT timer to generate a system clock.
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
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. This board is configured by default to use the OpenSDA DAPLink Onboard Debug Probe, however the pyOCD Debug Host Tools do not yet support programming the external flashes on this board so you must reconfigure the board for one of the following debug probes instead.
Option 1: OpenSDA J-Link Onboard Debug Probe (Recommended)
Install the J-Link Debug Host Tools and make sure they are in your search path.
Follow the instructions in OpenSDA J-Link Onboard Debug Probe to program the OpenSDA J-Link MIMXRT1050-EVK-Hyperflash Firmware. Check that jumpers J32 and J33 are on (they are on by default when boards ship from the factory) to ensure SWD signals are connected to the OpenSDA microcontroller.
Option 2: J-Link External Debug Probe
Install the J-Link Debug Host Tools and make sure they are in your search path.
Attach a J-Link 20-pin connector to J21. Check that jumpers J32 and J33 are off (they are on by default when boards ship from the factory) to ensure SWD signals are disconnected from the OpenSDA microcontroller.
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_IMX_RT_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:
Set the SW7 DIP switches to ON-ON-ON-OFF to prevent booting from HyperFlash.
Reset by pressing SW4
Run
west debugorwest flashagain with a known working Zephyr application.Set the SW7 DIP switches to OFF-ON-ON-OFF to boot from HyperFlash.
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 MIMXRT1052DVL6**A** to MIMXRT1052DVL6**B**
- 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
