You can read about the differences between these two here: MCUboot and nRF Secure Immutable Bootloader (NSIB)

Hi,

What is the difference between the Secure boot(NSIB) and Mcuboot ?

https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-9-bootloaders-and-dfu-fota/topic/exercise-2-dfu-over-usb-adding-external-flash/ -This course is having the secure boot.?

Secure boot(NSIB) which I was looking for the revoking and adding the multiple keys.

Thank you

Hi,

Here in the course, we can see the command to add key file. My doubt is can we do this by using Au-Term.

Another question is- Does this is a secure boot?

For the Mcuboot have to add the secure boot,does this meet the same?

To add secure do we have any course?

Please let me know answer.

Thank you

Hi,

AuTerm does not support key provisioning.

Could you please explain the problem you're trying to solve? As indicated earlier, the private key will not be placed on the device.

Hi,

I followed the same course to add the keys, By using Au-Term can we do this same instead of adding the key path into the code.

Can you give information about the Secure boot, for secure boot can we have to add configuration?

Thank you

Hi,

The Public key is included during the build process. For more information about the key management, please have a look at our DFU course here: https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-9-bootloaders-and-dfu-fota/topic/exercise-2-dfu-over-usb-adding-external-flash/

Hi,

Can you provide the mechanism reference to add the Publickey in the Mcuboot.

Public key will be Embedded in the Mcuboot FW image using the Au-Term?

Thank you

Hello,

There is currently no mechanism (or protocol support as far as I know) for adding or revoking keys. But only the public key will be embedded in the MCUBoot FW image.

Best regards,
