Hello Srinivas.V,

[quote user="Srinivas V"]Thanks for your reply.[/quote]

No problem at all, I am happy to help.

I would recommend bundling all your configuration #defines in a the sdk_config file, instead of spreading them out in different proprietary modules(unless you are using a separate config file for all your proprietary code modules, that practice is also fine). In both cases, I would recommend including your file in your main.c directly - or in your main proprietary code module - for clarity.

From the errors generated it seems some of the defines from the sdk_config does not make it to the preprocessor.
Is there any errors generated when you compile aes_Modes on its own?
Could you verify for me that the SEGGER_RTT_CONFIG_MAX_NUM_UP / DOWN_BUFFERS are defined in the sdk_config?

Best regards,
Karl

Hi Karl,

Thanks for your reply.

I have created a macros in one of my header file like

aes_Modes.h

#define CRYPTO_CC310 0
#define CRYPTO_MBEDTLS 1

if we add "aes_Modes.h" header file in "sdk_config.h" and do compilation we are getting below errors continuoulsy. if we comment this file it is compiling without any errors.

Regards,

Srinivas.V

Hello Srinivas.V,

Turbo J is correct with his comments about the proper preprocessor syntax, as well as the prompt for more information.

[quote user=""]If we add our own macros in "sdk_config.h" file we are getting some issues adn unable to add user defined macros in that file.[/quote]

Could you please elaborate on what you mean when you say this? What issues are you experiencing, is there any errors generated / does the project compile at all?

Looking forward to resolving this issue together,

Best regards,
Karl

Please elaborate. I don't see a problem here unless you try to use the CMSIS configuration wizard.

Note that your #else should rather be an #elif for correct preprocessor syntax.
