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?
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?
