System Clock
The MIMXRT1160 SoC is configured to use SysTick as the system clock source, running at 600MHz. When targeting the M4 core, SysTick will also be used, running at 240MHz
When power management is enabled, the 32 KHz low frequency oscillator on the board will be used as a source for the GPT timer to generate a system clock. This clock enables lower power states, at the cost of reduced resolution
Serial Port
The MIMXRT1160 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).
Building a Dual-Core Image
Dual core samples load the M4 core image from flash into the shared ocram
region. The M7 core then sets the M4 boot address to this region. The only
sample currently enabled for dual core builds is the openamp sample.
To flash a dual core sample, the M4 image must be flashed first, so that it is
written to flash. Then, the M7 image must be flashed. The openamp sysbuild
sample will do this automatically by setting the image order.
The secondary core can be debugged normally in single core builds
(where the target is mimxrt1160_evk_cm4). For dual core builds, the
secondary core should be placed into a loop, then a debugger can be attached
(see AN13264, section 4.2.3 for more information)
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.
Using J-Link
Install the J-Link Debug Host Tools and make sure they are in your search path.
There are two options: the onboard debug circuit can be updated with Segger J-Link firmware, or J-Link External Debug Probe can be attached to the EVK. See Using J-Link with MIMXRT1160-EVK or MIMXRT1170-EVK for more details.
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 mimxrt1160_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 v2.6.0-xxxx-xxxxxxxxxxxxx *****
Hello World! mimxrt1160_evk_cm7
Debugging
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b mimxrt1160_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! mimxrt1160_evk_cm7
