Hi Mr YK,

Firstly, both SMART3 and AI2MAX don't store the keys in OTP.
But I guess you are interested in keystore, not OTP.

1. List of the data stored in the OTP area of Smart3, AI2 MAX, UHD4
serial number, device ID, BT/ETH MAC, widevine key, playready key, HDCP 1.4/2.2 key, attestation key

2. All keys = values (widevine key, manufacturer serial number, etc.)
I think the answer is same as 1, could you please describe this item in detail?

3. Format of the value
string: serial number, device ID, BT/ETH MAC
binary: widevine key, playready key, HDCP 1.4/2.2 key, attestation key

4. Values that can be used as device Identifier
serial number, device ID, ETH MAC

5. Whether you can additionally remotely fusing the OTP
OTP can't change again, but keystore could change.
However, change secure keys(binary format) in AI2MAX would lead to function fail because they are bond to OTP.
changing the string format part is ok.

6. How to read data from OTP
the string format part, for ex the serial number and device ID,
they are read from the uboot and turn into property in linux (through kernel bootargs).
so we can read them through getprop

the binary format part is not readable
