Copying flash whole flash memory on chip

[Arepa]

Hi there,

Recently I bought an LTE module which uses a nRF52840 as the main processor to control the modem, I want to erase the flash for that module and flash the project I have been developing for months using the Nordic SDK

it should be simple use nRF Studio to erase the memory and flash my program, but I want to save the preinstalled firmware what is already flashed on the module, it includes Bootloader+Softdevice+APP, using nRF Studio as far as I understand it reads only the APP sections and indicates it is using a Softdevice (no copying it in the output file), I am not sure if it reads and copy the bootloader

What tool can I use to copy the whole flash memory app+sd+bootloader and have it as a backup?

Regards

Hi Arepa, 

The nRFGo Studio tool is old and being deprecated. 

We would suggest you to use the programming tool comes with nRF Connect instead. 

You can also use the command line tool nrfjprog.exe which is the most powerful tool for the purpose. To read out the flash, including UICR, you can use.
nrfjprog.exe  --readcode --readuicr filename
