dear freescale team.
i could see about OTPMK in some manuals .
The OTPMK is same with OTP_SRK[0~7] ?
it's really confusing.
it does not mention about OTPMK in IMX6DQRM.pdf file.
i can find only OTP_SRK.
there are SFP_SRKHR n(Super Root Key Hash n) , One Time Programmable Master Key n (SFP_OTPMKRn) each in case of other freescale board in the fuse...
thank you.
HI MyungJin
one can determine if a valid OTPMK has been burned by checking the
OTPMK_ZERO bit in the SNVS_HP Status Register.
In early pre-production parts they did not have the OTPMK fuses provisioned.
On production parts, the OTPMK are be burned by Freescale prior to shipping the
device. The value burned by Freescale is random and not recorded. The intent
of the OTPMK is to be a secret key that is only known to CAAM.
Best regards
