  I want to write some user information in the OTP memory at manufacturing. There are about 40 bytes is not used in our 43362's OTP memory. I want to use 32 bytes to save some user information. From page 18 in the "OTP Programming Procedure", the CIS format is <80> <length> <tag> <value>. So I want to add a tag to save this 32 bytes: 80 32 <tag> <32 bytes data>. Can you tell me which tag I can use?

  Another question: I can use IOCTL "cisdump" to dump the OTP by the manufacture firmware, but this command is unsupported in the normal firmware. Can you help to add a command to dump the OTP in the normal firmware?

Thanks!

Normal firmware doesn't support "cisdump".

BCM43362's OTP is not for user application.

Could you consider using something other like external EEPROM/Flash for the 32byte unique data?
