Input capture on PTC14(FTM1_Ch2) and PTE4 (FTM2_CH2) not working for s32k144

Hi,

I am using input capture on PTC14 (FTM1_CH2) using S32k144 EVB. But the output measured frequency its showing is 0Hz always. Same its happening for input capture on PTE4(FTM2_CH2).

Interesting thing is it works (measure correct input frequency) for PTB3 (FTM1_CH0)and PTC5(FTM2_CH0).

I am attaching my code. Let me know if I am missing something.

Thanks in advance.

Regards

-Ashwini

Hi Ashwini,

It seems like the PTC14 and PTE4 pin are not routed to the FTM modules.

I added them like this:

Please double-check the pin configuration and update the generated code.

Thanks,

Daniel
