System Clock¶
The MIMXRT1170 SoC is configured to use the 24 MHz external oscillator on the board with the on-chip PLL to generate a 1 GHz core clock.
Serial Port¶
The MIMXRT1170 SoC has 12 UARTs. One 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 20-pin connector to J1. Check that jumpers J6 and J7 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 J5 and J8 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 J11.
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.
Before power on the board, make sure SW1 is set to 0001b
# From the root of the zephyr repository
west build -b mimxrt1170_evk_cm7 samples/hello_world
west flash
Power off the board, and change SW1 to 0010b. Then power on the board and open a serial terminal, reset the board (press the SW4 button), and you should see the following message in the terminal:
***** Booting Zephyr OS v2.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! mimxrt1170_evk_cm7
Debugging¶
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b mimxrt1170_evk_cm7 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 v2.4.0-xxxx-xxxxxxxxxxxxx *****
Hello World! mimxrt1170_evk_cm7
