We move the<BR />signal on pad TAMPER but no IRQs arrive....</P><P>Thanks in advance,</P> Wed, 16 Feb 2022 13:48:38 GMT https://community.nxp.com/t5/i-MX-Processors/tamper-pin-IMX6Q/m-p/1414495#M187064 marcomaioli 2022-02-16T13:48:38Z https://community.nxp.com/t5/i-MX-Processors/tamper-pin-IMX6Q/m-p/1416750#M187276 <P>The external tamper functionality is not implemented&nbsp;in the Linux BSP for i.MX6Dual/Quad processor.</P> <P>Best Regards,<BR />Artur</P> Mon, 21 Feb 2022 11:42:59 GMT https://community.nxp.com/t5/i-MX-Processors/tamper-pin-IMX6Q/m-p/1416750#M187276 art 2022-02-21T11:42:59Z
