Hash of Image during confirm the firmware

[Julien]

Hi,

I'm looking to implement the smp protocol in my central device based on nrf5 sdk, in order to update my new peripheral device based on ncs v2.6.1.

My questions are : how to generate the hash image sended when you want to confirm the image previously sended.

Do you have any documentation or explication about it ? 

I saw that is a sha256 encryption, but i do not know which data i need to perform this encryption.

Thanks in advance.

Regards,

Julien

Hi,

You can use the "state of images" command to retreive a list of images in the mcuboot slots and the hash digests. You can use this to determine which image you want to confirm.
