S32K396 RTD 5.0: eMIOS CH0/CH1 PWM Not Generated and Unexpected LCU Output Behavior

Hi NXP Team,

I am working on an S32K312 using S32 Design Studio 3.6.7 with RTD 5.0 (AUTOSAR 4.7). I have configured eMIOS to generate six PWM signals through eMIOS → TRGMUX → LCU → Output Pins for motor control.

I am facing two issues:

1. eMIOS CH0 and CH1 do not generate PWM, while CH2 to CH5 generate PWM correctly. Clock, Port, eMIOS MCL, eMIOS PWM, Global Time Base, TRGMUX, and LCU are all initialized successfully, and the PWM configuration for CH0 and CH1 is the same as the working channels.

2. I have observed unexpected behavior with the LCU outputs. When I set LCU Output Index 4 to 0, Output 4 continues to generate PWM, but Output 5 becomes permanently OFF. Similarly, when I set LCU Output Index 2 to 0, Output 2 continues to generate PWM, but Output 3 becomes permanently OFF. I expected each LCU output to operate independently, but changing one output appears to affect the adjacent output.

Could you please advise:

• Are there any hardware or RTD restrictions for using eMIOS CH0 and CH1 with the LCU?

• Is any additional TRGMUX or LCU configuration required for CH0 and CH1?

• Are LCU outputs internally paired or dependent in complementary mode?

• Is this behavior expected, or does it indicate an incorrect LCU/TRGMUX configuration or a known issue in RTD 5.0?

I have attached my project and configuration files for reference.

Thank you for your support.
