A sample application that can be used with any supported boards. eg. RPL. prints configuration info to the console. Below functionalities are tested:
Periodic pulse generation (an Oscilloscope or loopback may be required)
Input pulse timestamping (a pulse generator or loopback may be required)
Building and Running
This application can be built and executed as follows:
# From the root of the zephyr repository west build -b intel_rpl_crb samples/drivers/misc/timeaware_gpio
To build for another supported board, change “intel_rpl_crb” to that board’s name (if supported).
