Signing ARTIK 05Xs Production Code
Having compiled and loaded pre-signed code, you now need to understand the code signing process for ARTIK "s" modules. These do not accept loading of code unless it has been digitally signed with the correct security signature.
For the development version of your code image, you:
- Used the
codesignertool to sign your
tinyara_head.binimage with a default key
- Flashed the
tinyara_head.bin-signedversion to your module.
For the production version of your code image, you need to:
- Use the KMS portal to sign your
bl2.binimages with your unique key
- Flash the
bl2.bin-signedversions to your module.
Note: For mass production, you must change wwwkey from 6 to 7 by e-fusing the relevant bit, using the wwkeysel API.
