Hi, I bought the protected memory with the protocol SHA-1 "bq26100" and I wrote my software routines to make it work. Momentarily to my tests use the secret key present when the memory is virgin (0x00000000. .. 000). The only thing that I could not tell from the datasheet is how to permanently store the secret key in memory without using the evaluation software and the evaluation board, but with my c code. How can I generate the secret key to be transferred into memory? It needs a random or defined message, and then what?
