S32k144 JTRST Toggle issue

Hello nxp community

There is a problem with running s32k144.

I am making a custom board with s32k144 chip and running it.

I confirmed that all 5v is normally applied to the power pin.

The problem is that the PTA5 JTRST pin is constantly being toggled, so it cannot even enter the debugging mode.

Any advice would be appreciated.

Hi @ldj979 

Could you please let me know if you have already programmed your MCU?
