CC1311R3: How to use MCUBOOT 2.0 to encrypt OAD image?

Shuyang Zhong

Part Number: CC1311R3
Other Parts Discussed in Thread: CC1314R10, CC1312R7

Tool/software:

I see in SDK 8.30 release note that MCUBOOT is supporting encrypted image now, but I didn't find an example for this new feature.

How to use this feature to encrypt the OAD image?

1. How to encrypt the image to be updated? Does the img tool support encryption?

2. How to set up the MCUBOOT to enable encyption/decryption?

Best regards,

Shuyang

Hi Shuyang,

I saw you put CC1311R3 in this title of this thread. Just so you know, we currently don't have an example of MCUBoot on CC1311. (We have examples on CC1312R7 and CC1314R10 and the other devices with these flash sizes.)

1. Yes the MCUBoot imgtool supports this. https://github.com/mcu-tools/mcuboot/blob/main/docs/imgtool.md

2. You can find documentation for using encrypted images with MCUBoot here:

https://docs.mcuboot.com/encrypted_images.html

Please note, none of our oad enabled examples currently showcase encrypted images.

Cheers,

Marie H
