Supported Features¶
The mimxrt1015_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 |
| I2C | on-chip | i2c |
| UART | on-chip | serial port-polling; serial port-interrupt |
The default configuration can be found in the defconfig file:
boards/arm/mimxrt1015_evk/mimxrt1015_evk_defconfig
Other hardware features are not currently supported by the port.
Connections and I/Os¶
The MIMXRT1015 SoC has five pairs of pinmux/gpio controllers.
| Name | Function | Usage |
|---|---|---|
| GPIO_AD_B0_05 | GPIO | LED |
| GPIO_EMC_09 | GPIO | SW4 |
| GPIO_AD_B0_06 | LPUART1_TX | UART Console |
| GPIO_AD_B0_07 | LPUART1_RX | UART Console |
| GPIO_EMC_32 | LPUART4_TX | UART Console |
| GPIO_EMC_33 | LPUART4_RX | UART Console |
| GPIO_AD_B1_15 | LPI2C1_SDA | I2C SDA |
| GPIO_AD_B1_14 | LPI2C1_CLK | I2C SCL |
System Clock¶
The MIMXRT1015 SoC is configured to use the 24 MHz external oscillator on the board with the on-chip PLL to generate a 500 MHz core clock.
Serial Port¶
The MIMXRT1015 SoC has four UARTs. LPUART1 is configured for the console,
and the remaining are not used.
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.
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 10-pin connector to J55. Check that jumpers J47 and J48 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 J45 and J46 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 J41.
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 mimxrt1015_evk samples/hello_world
west flash
Open a serial terminal, reset the board (press the SW9 button), and you should see the following message in the terminal:
***** Booting Zephyr OS v1.14.0-rc1-1297-g312d75f2459e *****
Hello World! mimxrt1015_evk
