How to disable TFM_CRYPTO_AEAD_MODULE_ENABLED

[Tide]

Hi,

Due to the flash size limitation, we want to reduce the code size of TF-M. After I set CONFIG_TFM_CRYPTO_AEAD_MODULE_ENABLED=n in SDK v2.2.0, the size of TF-M code can be reduced by about 32KB, but the program does not run into the main of the app, but into tfm_hal_system_halt. 


How to turn off TFM_CRYPTO_AEAD_MODULE_ENABLED?
Or how to configure TF-M to reduce code size?

Also, we need to set CONFIG_TFM_PROFILE_TYPE_NOT_SET=y instead of using TF-M mini mode.

Hi Tide,

We are aware that TF-M takes quite a lot of space, some customers have asked about this recently. I can say that space optimization is a work-in-progress for the TF-M team. As a starting point for now, please take a look at my colleagues reply on this topic:

Hi  Raoul,

SDK v2.3.0 has been released. Does this SDK solve the problem we are discussing here?

Hi Tide,

As far as I know, not yet. Sorry.

Best regards,
