Hi everyone.

I am getting this problem when I set an output pin on a K20 using


GPIO_DRV_SetPinOutput() function.

This pin enables the power for a section on my board, so I checked if voltage dips are happening on the rail powering the K20 when switching. A 2 mV dip is appearing so I think the problem is not because a power fluctuation.


I am using MQX 4.2.

Any way to know what is going on?
