S32 Design Studio for S32 Platform S32K144 GPIO output has no response

[MrShen]

Hello, I created the project using the example routine; modified the PIN and peripheral configurations and updated the source code; modified the output part of the program; used J-link for debugging, but the output pins A13 and D17 did not change! I am not sure where the configuration problem is, please advise!

Hello @MrShen ,

In AUTOSAR MCAL, the DIO module does not configure pin mux/direction. The pins used by Dio must be configured in the Port driver (PortConfigSet: PortPinPcr, pin mode/mux to GPIO, and direction/output level). Also ensure Port_Init() is called before any Dio API is used.

Best regards,
