Does the mm-iot-sdk support secure boot on the mm8108-ekh05-01

Hi,

Our product is built on the mm8108-ekh05-01 using the mm-iot-sdk. We require the device to support secure boot protection. Does the mm-iot-sdk offer this capability?

Thanks,
Owen

Hi @Owen ,

The STM32U5 will support secure boot, but you will need to manually implement it.

We do not currently support secure boot on our MM-chips.

The secure boot example we’re currently researching is STM32U585 SBSFU.

The architecture seems overly complex, and we’re concerned about unpredictable difficulties porting the mm-iot-sdk.
If we only need secure boot to firmware verification, do you have any specific suggestions?

Hi @Owen,

My understanding is that the example you’ve linked is for secure boot on the STM32.

Given this, we are unable to help you here, as you would be responsible for implementing this.
AFAIK, there should not be any differences between porting MM-IoT-SDK on a Secure Boot MCU vs Non-Secure boot, so if you already have it working, it should continue to work.
