Support of WolfSSL on Aurix TC4d

[Narratot]

Version

5.7.4

Description

I am trying to use WolfSSL for a research Project with the Aruix TC4D,
Is there a adapted WolfSSL version for this chip - Or a guide on how to get it working? The issue is, that the avaliable system libraries changed between aurix generations.
Thank you

Hi @Narratot,

Thanks for your interest in wolfSSL. There is no "out-of-the-box" configuration for AURIX TC4, nor special wolfSSL version for the chip, because there is not really anything AURIX-specific to get it to work. wolfSSL is highly portable, so the steps to build for AURIX would be the same as building for any generic target.

I recommend starting with the user_settings.h template in examples/configs/user_settings.h, and turning on/off features that you need via the #if 0 switches present in the file. See the "building wolfSSL" section of the wolfSSL manual for more details on each feature.

You can also look at examples/IDE/GCC-ARM for more inspiration on a configuration that targets a generic cortex-m microcontroller that would be a good start (though make sure not to uncomment/enable any of the ARM-specific optimizations). But if you compile the source files with a build configuration similar to cortex-m, making sure no ARM-specific assembly optimizations are used, then you should be able to arrive at a configuration that works.

Don't hesitate to reach out to us at [email protected] if you have issues compiling the library.

Best,
Brett
