Hi

If you refer to the S32K3 PORT Driver User Manual(RTD_PORT_UM.pdf), you will find an important note:

In order to be able to use the debug capabilities, the JTAG and Reset pins need to be configured in the Port driver using mechanism B. This means that the following pins/functionalities need to be added in the UnTouchedPortPin list:
– Reset_b having PortPin Mscr set to 5 and SIUL2 Instance set to SIUL2_0
– JTAG_TMS having PortPin Mscr set to 4 and SIUL2 Instance set to SIUL2_0
– JTAG_TDO having PortPin Mscr set to 10 and SIUL2 Instance set to SIUL2_0
– JTAG_TCK having PortPin Mscr set to 68 and SIUL2 Instance set to SIUL2_0
– JTAG_TDI having PortPin Mscr set to 69 and SIUL2 Instance set to SIUL2_0

Did you add the UnTouchedPortPin configuration mentioned in RTD_PORT_UM.pdf under PortConfigSet?

Best Regards,
Robin
