EIRQ Configuration for SK32 K311 triggering Reset handler

Ajit11 — Mon, 09 Mar 2026 09:50:18 GMT

Hello NXP Team,

We have created a project using RTD 3.0.0 P07 NXP S32K311 MCU . Using MCAL we have created configuration to use PTB9 and PTB11 as external interrupt. But During program execution at port_intit() function call MCU is entering into RESET handler.

Kindly support to resolve this issue. Find the screenshots of all Initialization function call and RESET handler function call.

Hi @Ajit11

Could you please share your .mex file so we can verify whether the issue is caused by a missing or incorrect configuration?

Also, just to make sure everything is set up correctly, please verify that the pins you configured in the Pins Tool are also added in the Port driver, and that the JTAG pins are included in the UnTouchedPortPin list:

RESET_b → PortPin MSCR = 5
JTAG_TMS → PortPin MSCR = 4
JTAG_TDO → PortPin MSCR = 10
JTAG_TCK → PortPin MSCR = 68
JTAG_TDI → PortPin MSCR = 69

BR, VaneB
