I'm working on a project that needs to monitor a GPIO to see if it goes high then back to low and deep-sleep when no activity. So I have started experimenting with the ULP coprocessor using the pulse counter examples/system/ulp/ example and am getting the RTC interrupt when ulp executes`wake` instru...

And in the documentation they have mentioned that some FreeRTOS functions are flagged as untested that haven't been fully vetted to be compatible with th...
