Read fimware hash for MCUBoot OTA

[thanosPr]

Hello Guys,

I am trying to implement our own firmware update over ble in Mobile App.

The whole process is succesfully done by Nordic Application (Device Manager).

I would like to read hash firmware in order to check slot0 and slot1 corresponding hash.

Could you please guide me how to read hash firmware of the mcuboot generated app_update.bin?

Thanks in advance,

Thanos Prionas

Hi,

Do you want to read the hash from the nRF chip, a computer  or a mobile phone?

I solved my problem!

I run imgtool.py in my pc and getting correctly the firmware hash.

Good job!

Can you share the exact imgtool command that you used to get the hash?
