Secure Boot + Secure Update

[alereale]

I would like uploading in RAM a signed image (included with hash and digital signature) and verifying its authentycity and integrity at secure boot time.

I don't want use an sb3 structure but a custom structure with an header (where there is hash and digital signature) and the image to be started.

Can I use sss api in my custom bootloader? I cannot find any examples for verifying my image with KW45 and EdgeLock.

Thank you

Alessandro

Hi Alessandro,

by sss API you mean ROM API? Probably this question should go to SDK forum, if you miss some example (in SDK).
