STM32F4 clock bug

Andreas Kölbl <andreas.koelbl@...>


I'm working on a stm32f4_discovery board (defconfig). No changes besides enabling GPIOs.

The blinky example works, but the k_sleep call is about ~2.x slower than expected. Digging a bit deeper, the k_timer shows the same slow motion effect.

Anyone experiencing similar behaviour on that board?

Do I have to change some timer settings? Actually I thought that default settings for that board would provide an accurate setting.
