Has anyone else tried running the “GPIO” sample (BareMetal) project? The LED blink intervals are supposed to be 125, 250 and 500 milliseconds but they are not.
When I run the unmodified sample code and connect an oscilloscope I see that each interval is actually about 50% longer, i.e. 250 ms is actually 375 ms, 500 is actually 750 ms, etc.
I’ve seen the note in the Gpt_LaunchTimerMs function saying the accuracy ultimately depends on the clock source, but 50% is a big error.
