You can consider this ticket resolved. The order of includes MbedTLS files includes was the problem, <mbedtls/platform.h> needs to be at the bottom, if it needs to be included.

Hi,

Thanks for the reference, although it turned out to be not related to this...

Oh dear lord. It took me 2 days but I think I got this.
My application included

# include <mbedtls/platform.h>

which appears to introduce some of these MBEDTLS_PLATFORM_PRINTF and similar definitions not where it's expected. With a chain
my_header.h ->platform.h + ssl.h -> platform_util.h -> build_info.h -> check_config.h
MbedTLS check config found this conflict and gave compile time errors. Commenting out include platform.h helped.

I have no idea how and where these defines should be then, but I guess I don't care now.

Also this worked perfectly fine in older nCS version, so I could not expect such mess.

Hello,

you can look at the mbedtls related configs in this file.

Also, the legacy crypto API is being deprecated and will be removed in future releases. You can read about it here.

I have also tried defining these macros as regular exit, printf etc but maybe in a wrong header?
