Optimal wolfSSL configuration for DTLS 1.3 on STM32U575 MCU
Hello,
I am using STM32U575CGU6 MCU and want to use wolfSSL library with minimal flash consumption. My application intends to used DTLS 1.3 and no TLS use case is foreseen.
Note: The wolfSSL library version used is 5.7.6.
Kindly support me with following issues,
1. How can I correctly configure DTLS 1.3. It seems that the DTLS1.3 implementation is not available and the library configured over the tool just supports DTLS 1.2.
2. While using DTLS, I have to also necessarily configure TLS 1.3 and TLS 1.2 to compile the code. This increases the overall code memory. Can this be avoided? Am I missing some configuration step here.
3. The video- " https://www.youtube.com/watch?v=pUd2HEfBp3w " explains "How to use wolfSSL software expansion for STM32Cube". However, the downloaded pack does not provide any ,ready to use ,.ioc sample file for wolfSSL tests (for NUCLEO-U575ZI-Q board). Where can I find this?
4. The " https://github.com/wolfSSL/wolfssl/blob/master/IDE/STM32Cube/default_conf.ftl " and the generated "\wolfSSL\wolfSSL.I-CUBE-wolfSSL_conf.h" file have some discrepancies. For example, there is an additional "WOLF_CONF_TLS12" in the generated header file. Why do I see this difference, when using the same version?
Thanks.
