I'm quite new to zephyr and I'm working on a stm32f4_discovery board
I tried the blinky application from examples (enabled the corresponding
GPIO in the config).
I didn't change the base clock setup from the configuration. With that,
I discovered the k_sleep interval is kind of wrong. It sleeps about 3,5
times longer than it should be.
I also tried another GPIO-Pin (PB8) to toggle instead of the LED in the
example and measured the frequency with a scope. It measured an
frequency (ACTIVE_HIGH->ACTIVE_HIGH) of 214.09mHz which should be 500mHz.
Am I missing something here?
