How to flash using HEX and SoftDevice

How to program flash with the output HEX file and SoftDevice file using NRF52-DK.

When programming with the output HEX file the device does not work, I need also HEX - SoftDevice.

Hi!

You can use the Programmer application in nRF Connect for Desktop to flash a HEX-file to your DK. If your application uses BLE you will need to add the SoftDevice first and then the application HEX file on top of that and select Erase & write.

But i need flash extern device connected to the NRF52-DK.

Okay? Why is that a problem?

[BartoszT]

nRF Connect write program to the NRF52-DK and not to the external device.
Programming and Debug in Segger IDE works with NRF52-DK but I need seperate tool for flashing.

If you're using the nRF52 DK as the external debugger for your own device, how are you connecting them?

So, just to make sure there are no misunderstandings. 

When you use a  DK as an external debugger, you connect it to the custom board like described in the picture you linked to.

And then, using the Programming application, you select the nRF52-DK and flash the application you want to the DK and it will be rerouted to your custom board if you have connected it properly. 

Do you understand?
