S32DS SDK S32PA RTM 2.0.0 & RTM 3.0.0 SIUL2 interrupt issue

[Pat]

Hi jiri.kral@nxp.com‌,

During the  PINS_DRV_Init()-PINS_Init(), when the external interrupt EIRQ0 is enabled first, it will be cleared when a next pin configuration is defined as input and interrupt disable. Issue also present in RTM 3.0.0.

MCU used is MPC5744P.

1. In both case line 152 pinIntValue = 1u.       pinIntValue = (1UL << config->intConfig.eirqPinIdx);
2. g_pin_mux_InitConfigArr[0] line 188 set DIRER0.EIRE0 bit.   config->base->DIRER0 |= pinIntValue;
3. g_pin_mux_InitConfigArr[1] line 202 clear DIRER0.EIRE0 bit.   config->base->DIRER0 &= ~pinIntValue;

Hello Pat,

The issue has been confirmed in PINS driver. As a workaround please configure EIRQ at the last index of the PINS config array, in the generated code.

A fix will be provided in the next release - S32SDK for PA RTM-SR 3.0.1

Thanks and regards,

Cosmin
