The mimxrt1015_evk board configuration supports the following hardware features:
|NVIC||on-chip||nested vector interrupt controller|
|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 I/Os¶
The MIMXRT1015 SoC has five pairs of pinmux/gpio controllers.
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.
The MIMXRT1015 SoC has four UARTs.
LPUART1 is configured for the console,
and the remaining are not used.
Programming and Debugging¶
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.
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
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
