How do I know the checksum value from HEX file?

[jake.s]

Hi, I'm currently using nrf52840 MCU for product development and almost finished my project. What I want is when producing a product, I want to compare the checksum of the firmware to check whether the firmware file is correct. How can I see this value?

Hi

There is a verify function in nrfjprog you can use to verify the flashed file, but it depends on what you're using for programming your device I guess. I'm afraid our tools don't have any checksum features specifically, but there are various software deliveries that can do so. An example is Ubuntu ISO downloads. 

Best regards,
