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?

[Marte Myrvold]

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.

Best regards,

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.

Best regards,

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.

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
