Hi @matthewc
May I know why you are using the memory_buffer_alloc.c feature?
Is it only to replace the calloc and free functions or is it because you would like to use static memory?
If it is only to replace the calloc and free, I would suggest you use your platfomr’s implementation of calloc and free, as the alternatives. As mentioned in this article and this post.
If it is a matter of reducing heap memory usage, note that the feature is not a full Memory Management Unit implementation, and was used only for the Mbed TLS needs. Perhaps you could consider modifying the platform’s linker file in this case, to modify the heap memory on the expence of the static memory ( to keep same RAM usage.)
Regards
