STM32F030 HSI clock output on MCO pin

Hi,

I have configured my Nucleo-64 board with the STM32F030R8 with the STMCube software.

The HSI is set as system clock (no PLL) and measured over the MCO pin (PA8). I will attach the main.c.

The measurement you can see below.

Do you have some ideas what's the cause?

Thank you!

Can you look at it using an oscilloscope rather than a LA?

Yeah, that's it! With an oscilloscope there are no breaks inside. Thank you!
