Hard fault during access to FTM registers

[marcotrematerra]

Hello All,

I'm working on MKE06Z128, IDE used is MCUXPresso V10.1 and I use the SDK, like debugger I use the PE Multilink.

As title of this request, every time I wish to access to FTM register the microcontroller goes to in hardfault.

For example:
FTM0->SC = 0x00;

when the microcontroller arrives at this line it goes to hard fault. I don't know why.

Is there someone who help me to solve that problem?

Best regards,
Marco

I have exactly the same problem, KE02Z, using Processor Expert and enabling FTM0.

No resolution yet.

Hi Marco

The only explanations for a hard fault here are:
1. The FTM clock gate hasn't been enabled before use.
2. The peripheral block address used to the FTM module is wrong.
3. A non-existent FTM module is being accessed.

Attached is a reference for the FRDM-KE06 which has a periodic interrupt in FTM0 (flashing red LED at 150ms half-period). Command line interface on OpenSDA VCOM at 115200 Baud.

Regards

Mark
