Thanks for the research, Eric, but this is not quite the same issue.  I'm not getting undefined reference to `__HAL_RCC_AES_CLK_ENABLE' - I have that routine present in the build.  The problem is that I have to manually enable the crypto clock within the WolfSSL routines.

For example:

    static int wc_AesEncrypt(Aes* aes, const byte* inBlock, byte* outBlock)
    {
        int ret = 0;
    #ifdef WOLFSSL_STM32_CUBEMX
        CRYP_HandleTypeDef hcryp;
        #if defined(NUCLEUS) && defined(WOLFSSL_STM32L4)
            /* Enable CRYP clock */
            __HAL_RCC_AES_CLK_ENABLE();
        #endif

Thanks so much, Eric!  What about the ECC requirement?

Thank you David.  We are on 4.6.0.  I will update.

Thank you!

Thank you, Kaleb.

I am porting WolfSSL to the Nucleus OS, so listing out the configuration options is a little tricky - also because I think I have some out of date configuration options in my port.  I am porting version 4.0.0 from a previous version.

I found a lot of macros in the code that are not documented in the latest WolfSSL manual as configurable, but Nucleus has allowed these to be configurable in the past.  Could you possibly verify whether these macros should be configurable by the user in the 4.0.0 version of code, please?  The problem may be that we have some legacy macros enabled that should not be toggled.

Hello Kaleb,

Thank you for your response.  I am referring to documentation at this link.  https://www.wolfssl.com/documentation/w … Manual.pdf

Is this the proper document that I should be using?

Thanks,
Tammy
