undefined reference to `mbedtls_aes_init' in SDK_2.9.0

[SunHuang]

Hi,

As shown below, which configuration should I use to resolve the error?

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.

Best regards,

Hi,

Simply add the following code to the sample program, or directly replace the files in your project with the attached files.

app_task.cpp

#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,

Hi,

You can also create a new project, and you should be able to easily find the same error.

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.
