Dear danielmartynek :

Thank you for your reply,i have check my board,unfortunately,SWO is not supported.

I'm going to use the UART channel to output the log.

Hello,

The S32K148 MCU supports SWO.

I haven't used it with S32DS though.

Regards,

Daniel

Hi danielmartynek :

The board that I'm using now, the TDO port is not connected,I will try to pull out the TDO port and test it again.
