Subject: [tpm2] regarding a storing a data in nv memory of tpm , without using
authorisation or key storing techniques.
actually main problem is we interfaced slb 9670(tpm-2.0) with 16 bit msp430 controller
which does not support linux kernel or any OS.
now our task is to store a 100 byes of data in NV memory, without any authorisation
technique, as simple as possible.
please guide me in that way.
slb 9670 is interfaced with msp430 controller through SPI protocol.
I able to read device id , version id of slb9670 , so spi communication is working fine
with our controller .
what is packet format to be send with our data , i am not able to understand the TCG
theoretically iam able to understand we have to do nvdefinespace , nvwrite ,nvread ..
internaly what is the format i have to be send not able to understand
can you please guide me , or share any code snippet .
sorry if i trouble you or any irrelevant questions.
