We are developing a product using imx6-sl. We want to add support to detect tampering whenever case/box is unauthorizedly opened.
I have seen Pin named Tamper. however I haven't seen any instruction on interrupt handling for the Tamper Pin in the reference-manual. Would you please help me to add support for the driver?
Please use the Security Reference Manual for i.MX 6SoloLite.

Hi Yuri,
The document helped , thanks a lot for that ...
I now know the registers that can be used to handle the tamper functionality.
But the problem is that , quite some registers are marked "Privileged Write access" .... They say that, only privileged software can write to these registers .... but i didn't quite get as to what is meant by privileged software ....
Can you pls point me to what could the document mean by privileged software .... ?? i.e. how can I get an access to these privileged registers ... ??
Thanks in advance !!
Please take a look at the following :
