External tamper detection in i.Mx7D

[sharmilad]

Hi,

   We are using i.Mx7D processor for one of our product. We want to test the External Tamper detection mechanism in our device which will trigger violation and zeroize key information when the device encounters unauthorized opening or tampering. We have used SNVS_TAMPER0 pin for this purpose. Do you have any test code for testing the same.

Thanks & Regards,

Sharmila D
