Hello,
we're using an iMX6Dual based board with linux 5.4.129 and we'd like to enable
tamper detection on pad TAMPER (signal SNVS_TAMPER).
Looking into the driver linux/drivers/crypto/caam/secvio.c it seems to us that
LP registers are never touched... so we're puzzled to know how the
"external-pin-tamper" in the driver should take effect!
Is this the right driver to use or we needed something different? We move the
signal on pad TAMPER but no IRQs arrive....
Thanks in advance,
The external tamper functionality is not implemented in the Linux BSP for i.MX6Dual/Quad processor.
Best Regards,
Artur
