Errors in compiling Crypto Example Code on NUCLEO-L152RE

Mbed TLS Crypto and SSL questions
1

I am trying to run the crypto example code (GitHub - ARMmbed/mbed-os-example-mbed-crypto: Mbed Crypto example for Mbed OS 5) on NUCLEO-L152RE. The program is compiled correctly but I am getting error in linking as shown in the attached screenshots. Can someone please check it and let me know what is wrong? I think there is a problem in configuration.

Hi @aisha11,
Thank you for your question.

Do you have MBEDTLS_CTR_DRBG_C and MBEDTLS_ENTROPY_C defined in your configuration?
Regards,
Mbed TLS Support
Ron

Hi Ron,

In mbedtls_user_config.h file (which is on the root of getting-started directory), only 'MBEDTLS_PSA_CRYPTO_C 'is defined as follows:

/* Enable PSA APIs, which this example depends on. */
#if !defined(MBEDTLS_PSA_CRYPTO_C)

define MBEDTLS_PSA_CRYPTO_C

#endif

Where shall I define these two MBEDTLS_CTR_DRBG_C and MBEDTLS_ENTROPY_C and how?

Hi @aisha11

Please check if these are defined in getting-started/mbed-os/features/mbedtls/inc/mbedtls/config.h.
If not, you can define them in mbedtls_user_config.h as well.

If they are defined, please show symbols of ctr_drbg.o and entropy.o
Regards

MBEDTLS_CTR_DRBG_C and MBEDTLS_ENTROPY_C are defined in ‘getting-started/mbed-os/features/mbedtls/inc/mbedtls/config.h’ .

The symbols for ctr_drbg.o are as follows:

ctr_drbg.o

Hi @aisha11

Please run arm-none-eabi-nm on these “.o” files to get the symbols.

7

Hi,

I do not know how to run this. I tried like this, ‘arm-none-eabi-nm ctr_drbg.o’, but there is no output.

8

There is no output

This is probably because the debug symbols were stripped.
Pleasae try building with debug profile.( add the parameter --profile=mbed-os/tools/profiles/debug.json to your build command), and run the arm-none-eabi-nm command as well.
Regards

Hi Ron, I just compiled again by using debug profile. I am getting the same errors in linking. Here is the error log.

Hi @aisha11
As you can see from the symbols, the configuration file that is used is " confignoentropy.h"

This is because:

#if !defined(MBEDTLS_ENTROPY_HARDWARE_ALT) && !defined(MBEDTLS_TEST_NULL_ENTROPY) && \
    !defined(MBEDTLS_ENTROPY_NV_SEED)

And your target doesn’t have an existing entropy source ported.

Hi Ron, thanks for your reply. So, how can I resolve it?

12

Hi @aisha,
If you need this for development and test purposes only, you could try adding MBEDTLS_TEST_NULL_ENTROPY in your mbedtls_user_config.h file. However, this is not secure.
Since the platform doesn’t have an entropy source, you could consider porting an NV seed
If this is not feasible, then you should consider using a different target.
Regards

13

Hi Ron, many thanks for your reply. Can you please recommend some targets which are suitable for running the Mbed Crypto and Mbed TLS. I want to work on a device with similar specs.

14

Hi @aisha11
Here you will find Mbed OS supported boards, which have TRNG enabled
