IMX8QXP: tamper pins usage

pierluigi_p — Wed, 11 Mar 2020 18:24:19 GMT

Hi,

I'm interested in using tamper pins for tamper detection with iMX8QXP in Linux.

In the iMX8QXP Reference Manual I can find several information but nothing usable from kernel/userspace.

The Yocto documentation does not provide specific details but the reference to SECVIO_CAUSE_TAMPER_DETECT violation interrupt in CAAM/SNVS.

Is there any basic documentation with sample usage?

Thanks

Best Regards

Pier

Hi Pier

>Is there any basic documentation with sample usage?

unfortunately not sorry since this part is "PREPRODUCTION" as described on below

and not fully supported.

Full support will be available after public release, additional

documents will appear on official product web page

Best regards
