How to use Image authentication API ?

We need to check signature of an application located after the bootloader. We think use the image authentication api to do that. 

We tried to call  "skboot_authenticate" function without success ( HardFault ). Do you have an example for this ?

Tks

Hi,

Unfortunately, we don't have an example like you need, however you can check the following application notes:

Have a great day,
