Code source fo internal clock for NXP S32K146

[sebastien_ledio]

Hello,

I am developping SW on S32K146 NXP microprocessor. Actually I use an external cristal for system clock. The SW runs correctly.

Now, I would like to remove this cristal, so use the internal clock, but something does not work.

Someone can help me by give me an source code example to know how configure internal clock without cristal.

By advance, thanks a lot

Hi Sebastien Le Diouris

The default configuration out of reset has the CPU clocked by the Fast IRC (FIRC_CLK), so actually, you should be able to run the MCU without an external crystal. are you setting up the external clock in your startup file? could you clarify what part doesn't work, or what behaviour are you seeing?

Have a great day,
TIC
