Hi,
Do you have AES enabled in your project?
CONFIG_MBEDTLS_AES_C=y
Please upload the full build log as text using Insert > Code.

Hi,
I have already added this configuration, but it didn't change anything, so I created this thread.

Hi,
Please do a pristine build and upload the full build log.

Hi,
Since there is a character limit for text using Insert > Code, I can only provide you with the file. You can also create a new project, and you should be able to easily find the same error.
Hi,
SunHuang said:You can also create a new project, and you should be able to easily find the same error.
Have you made any changes to the project? Is it based on a sample from v2.9.0 or a different version of the SDK?
Based on the log file, I assume you use the Matter lock sample. I created an application based on this and built it for the same board as you (nrf5340dk/nrf5340/cpuapp), but I got no errors.
Best regards,
Marte
Hi,
I think you are not using AES related functions. For example: mbedtls_aes_init.
Hi
Please share a project where I can reproduce the issue or how to modify an SDK sample to reproduce it.

Hi,
Simply add the following code to the sample program, or directly replace the files in your project with the attached files.
#include "mbedtls/aes.h"
#include "mbedtls/sha256.h"
#include "mbedtls/base64.h"
CHIP_ERROR AppTask::StartApp()
{
ReturnErrorOnFailure(Init());
mbedtls_aes_context ctx_aes;
mbedtls_aes_init(&ctx_aes);
while (true) {
Nrf::DispatchNextTask();
}
return CHIP_NO_ERROR;
}
Hi,
Please also share the changes you have made to prj.conf and any other changes necessary to reproduce the issue.
Best regards,
Marte

Alright, I may not have expressed myself clearly. Let me rephrase it. In a brand-new project, which configurations should I enable to use the AES functionality?
To prevent other potential issues, as per your request, I have attached all the modified files from the project.
Hi,
You can solve the issue by enabling legacy mbedTLS crypto. However, Matter uses PSA crypto, and combining legacy and modern crypto drivers can cause issues. I strongly recommend using PSA crypto instead. You can find samples that use PSA crypto under the Cryptography samples section in our documentation.
To enable legacy crypto, set CONFIG_MBEDTLS_LEGACY_CRYPTO_C=y in prj.conf. Please note that this can result in issues and unexpected behavior.
Best regards,
Marte
Hi,
After using CONFIG_MBEDTLS_LEGACY_CRYPTO_C, many warnings appear during compilation, including prompts that CONFIG_MBEDTLS_LEGACY_CRYPTO_C has been deprecated. If you believe there are risks, please let me know how this version should be resolved.
