DWT + S32K344?

[MVR]

Hello everyone,

Is there DWT to get the cycle count in S32K344?

I took a look the refence manual, there are some notes about DWT but not with much detail.

I would like to use like this DWT type:

https://developer.arm.com/documentation/ka001499/1-0/

Thanks

Hi @MVR 

As mentioned in the posts, this implementation can be done on Cortex-M7 devices, the S32K344 has an M7 core therefore it has DWT, so the mentioned implementations should be functional.

Hello @VaneB ,

Nice, but is there documentation about it? What register do I need to check? I didn't find documentation about it...

Thanks.

The DWT es related to the core, so you can find all the available information for it in the arm website.
