Tamper function in i.MX6.

Hi.

I'd like the sample code of Tamper function for i.MX6.

Does the sample code exist?

Although the IMX6 chip supports the tamper function, but we haven't connected the tamper detection pin to IOMUX pad, so the function can't be used.

Dear Qiang Li,

Thank you for your reply.

I'd like to use tamper detection for Voltage, Temperature, SRTC, Wire mesh.

Are these features supported by i.MX6?

If it is supported, give me sample code.

I think they can't be supported.

The Tamper Detection signal is pulled-down internally. In case of use, it should be connected to a Tamper Detection contact in a target system (Normally closed, pulled-up to the VDD_SNVS_IN).

But due to the iMX6 hasn't connected this signal to external IOMUX pad, there is no external pin can be used to connect it to VDD_SNVS_IN.
