For max production procedure , how can I get hex file checksum in nRF_Connect_Tool ?

[Taiwan_Fitz_Edward]

Hello ,

I am a firmware engineer in Taiwan ,

I already use nRF52820 to finish one case ( cheaper alcohol/acetone BT checker.)

Now ,the engineering stage is pre_production.

I have one question , 

For max production ,how can I get hex file checksum for nRF_Connect_Tool ?

other MCU production : 
1.Release firmware hex file to  MCU IC programming manufacturer , and  give the hex file checksum.
2.MCU IC programming manufacturer would write hex file to MCU ,then read all hex file and get checksum to check programming if it is ok.

But , I did not see  checksum(or CRC)  function in nRF_Connect_Tool .

Can some give me a helping hand ?, thanks!

I used  nRF_Connect_Tool / programmer ,I hope the tool can show hex file checksum !

Because for max production , 
MCU IC programming manufacturer need use  checksum to verify if chip programmer writing hex file correct !

Hi,

You use nrfjprog tool with --verify argument for programming. With this command, image file contents are compared and the programmed image file is verified. Refer to "nrfjprog --help" for more information.
