Glad to hear that Eyal. I'll make note of that for future reference too. Thanks for letting us know, and don't hesitate to create a new ticket if you run into new issues.

Best regards,

Simon

I just wanna update that I found the .h with all of the defines and prerequistes for mbedtls.

It is called nrf_crypto_mbedtls_config.h and it's inside <SDK_PATH>\external\nrf_tls\mbedtls\nrf_crypto\config

I couldn't find it because it wasn't in the actual mbedtls folder.

I'm still testing it but it seems that after updating the defines it compiles fine and updates mbedtls

Hi again Eyal

Hmm, I can't say we're able to see what's missing here I'm afraid. But discussing this case with a colleague, we realized that since you don't actually use encryption or cryptography on your end, it might be easier to just remove embedtls and micro-ecc from the external folder in the SDK entirely. Would that be an option here?

Best regards,

Simon

The full error is:

#if defined(MBEDTLS_CERTS_C) && !defined(MBEDTLS_X509_USE_C)
#error "MBEDTLS_CERTS_C defined, but not all prerequisites"
#endif

in check_config.h.

I'm not sure where either MBEDTLS_X509_USE_C or MBEDTLS_CERTS_C are defined.

Can you let me know what prereqs these are exactly that you're looking for, and I'll help you look for them.

I can see the prerequisites I just don't understand where are they defined. I thought conifg.h in the include folder of mbed is the file that holds all of the defines but when I tried commenting on\off various defines it had no affect. is there any other place where those defines could be?

Are you able to see what prerequisites aren't defined, or see what prerequisites the MBEDTLS certs would need and make sure they're all defined in your project too. Sorry I don't have anything more specific to go on here.

HI,

Thanks for the answer. I tried replacing mbedtls to version 2.28.9 since I read that versions 2.xx shouldn't break coompilations. I copied the entire library into External\mbedtls\

When compiling I get the error "MBEDTLS_CERTS_C defined, but not all prerequisites". I've tried using the same config.h or CMakeLists.txt as the current version of mbedtls but it didn't help. Any ideas where to go from here?

Hi Eyal

1. In a perfect world it should be that simple, and although I think it is, we can't guarantee that it is. Please give it a try and see if that's sufficient.

2. To remove encryption, open you sdk_config.h file, search for any settings related to micro-ecc (NRF_CRYPTO_BACKEND_MICRO_ECC_ENABLED for example). Set all these options you might find to 0. At least the one mentioned as an example should prevent that library from being included in the build.

Best regards,

Simon
