Issue with pin configuration in S32DS3.4

[DenisT1980]

I have issue with pin configuration by S32DS 3.4.

I have configured the pin 1 of PORT C as GPIO output, but in the automatic created structure the direction is marked as GPIO_UNSPECIFIED_DIRECTION.

Hier is excerpt from pin_mux.c

Hi @DenisT1980,

Please specify the MCU and the RTD version.

Thank you

[DenisT1980]

MCU: S32K146

SDK Version 4.0.2

Hi @DenisT1980,

I can't reproduce the issue.

When I create a project from example,

hello_world_s32k146

PTC1 is a GPIO output by default

the pin_mux.c file is generated correctly:

Can you test it with that example?

Do you use Linux?

Thanks,

BR, Daniel

I have made my own research. As I have understood the fault occurs, if the pin is configured for more than one functional group.

I have created the test project from example „hello world“, as you described. The pin configuration in functional group „BOARD_InitPins“ was OK. Then I have created the new pins functional group „TestFuncGroup“ and configured for this group the PORTC1 as ADC channel 9. Now is the configuration for PORTC1 in BOARD_InitPins wrong.

[danielmartynek]

Hello @DenisT1980,

I juts tried to reproduce it, but it gives me an error that the pin is already configured in the default BOARD_InitPins function group.

BR, Daniel

[DenisT1980]

Please, check if both functional group are marked as "Called by default initialization function". Select only one function group.

[danielmartynek]

Hello @DenisT1980,

You are right, PTC1 has GPIO_UNSPECIFIED_DIRECTION in Arr0

But if I move the second group up like this:

It seems to be good,

Regards,

Daniel

But this make all my GPIO pins to OUTPUT, also such that are configured as INPUT!.
