Thank you for the feedback. I will, continue with my tests in incoming week, will check your update. Greetings!
Thank you again.
My use case is simple, I am automotive engineer, recently involved in the topics related to certificate handling with HSM/Keym components. By this occassion, I would like to learn about generic and mainstream crypto stack implementations, from embedded perspective. I stumbled upon Wolfssl and I think it is great learning opportunity as plenty material is available. Also reading introductory book about TPM 2.0. I assume in the future I'll have opportunity to focus on TPM more, as automotive systems go towards bigger SW platforms nowadays.
Thank you for your reply. I added this definition and few more as well to compilation symbols and test proceeds further. Though I get one non-critical and one critical fault. But no easy conclusion what do I miss to enable this time...
Greetings,
Wojt

Hello
I set up Wolfssl and WolfTPM from STM IDE, read available documentation before. And use ST33TP on SPI2. Connection is up and running after minor adaption of IO callback.
Earlier made test+benchmark of WolfSSL+WolfCrypto on H743 Nucleo board and that worked fine including all symmetric/assymetric cryptography. But it was SW wolfcrypto based.
So, I attach the log. I encountered unresolved dependency, it seems that from STM32IDE I can't setup WolfCrypto settings to activate needed feature -> WOLFSSL_AES_CFB in this case. Is it configurable from command line only?
Greetings,
Wojt
