The i.MX RT1050 is a new processor family featuring NXP’s advanced implementation of the ARM Cortex-M7 Core. It provides high CPU performance and real-time response. The i.MX RT1050 provides various memory interfaces, including SDRAM, Raw NAND FLASH, NOR FLASH, SD/eMMC, Quad SPI, HyperBus and a wide range of other interfaces for connecting peripherals, such as WLAN, Bluetooth™, GPS, displays, and camera sensors. As with other i.MX processors, i.MX RT1050 also has rich audio and video features, including LCD display, basic 2D graphics, camera interface, SPDIF, and I2S audio interface.

Supported Features

The mimxrt1050_evk board configuration supports the following hardware features:

Interface Controller Driver/Component
NVIC on-chip nested vector interrupt controller
SYSTICK on-chip systick
GPIO on-chip gpio
UART on-chip serial port-polling; serial port-interrupt

The default configuration can be found in the defconfig file:


Other hardware features are not currently supported by the port.

Connections and IOs

The MIMXRT1050 SoC has five pairs of pinmux/gpio controllers.

Name Function Usage

System Clock

The MIMXRT1050 SoC is configured to use the 24 MHz external oscillator on the board with the on-chip PLL to generate a 600 MHz core clock.

Serial Port

The MIMXRT1050 SoC has eight UARTs. One is configured for the console and the remaining are not used.

Programming and Debugging

The MIMXRT1050-EVK includes the NXP OpenSDA serial and debug adapter built into the board to provide debugging, flash programming, and serial communication over USB.

To use the Segger J-Link tools with OpenSDA, follow the instructions in the Segger J-Link page using the Segger J-Link OpenSDA V2.1 Firmware. The Segger J-Link tools are the default for this board, therefore it is not necessary to set OPENSDA_FW=jlink explicitly when you invoke make debug.

With these mechanisms, applications for the mimxrt1050_evk board configuration can be built and debugged in the usual way (see Build an Application and Run an Application for more details).

The pyOCD tools do not yet support this SoC.


The Segger J-Link firmware does not support command line flashing, therefore the usual flash build system target is not supported.


This example uses the Hello World sample with the Segger J-Link tools. Run the following to build your Zephyr application, invoke the J-Link GDB server, attach a GDB client, and program your Zephyr application to flash. It will leave you at a GDB prompt.

# On Linux/macOS
cd $ZEPHYR_BASE/samples/hello_world
mkdir build && cd build

# On Windows
cd %ZEPHYR_BASE%\samples\hello_world
mkdir build & cd build

# Use cmake to configure a Ninja-based build system:
cmake -GNinja -DBOARD=mimxrt1050_evk ..

# Now run ninja on the generated build system:
ninja debug
