Hi,
My product uses i.MX6ULL (MCIMX6Y1DVM05AB) and I found TAMPER_PIN_DISABLE[1:0] is already written to 11b which means "disabled". Is that correct?
# cat /sys/fsl_otp/HW_OCOTP_CFG2
0x79f100f5
# cat /sys/fsl_otp/HW_OCOTP_CFG2
0x79f100ca
Thanks,

Hi enginlee,
Yes, it is disabled.
Tamper function is used for POS, it is enabled in i.MX6UL ,whose part number includes G2, for example:
MCIMX6G2DVM05AA(B/C/D)
MCIMX6G2DVK05AA(B/C/D)
these part numbers are designed for POS.
Hope these information is helpful for you.
Have a nice day!
