Yes, I was expecting that the order was the problem. ;-)

Then something with mergehex. Its ok as long as this is solvable by reversing the order. Can you please attach your two hex files zipped here so that later the team looks into it. Thanks for your time :)

Yes, the files are identical.

erase your device -> nrfjprog -e
1. flash softdevice -> nrfjprog --program S120_softdevice.hex
2. read uicr -> nrfjprog --readuicr soft.uicr
3. flash application -> nrfjprog --program application.hex
4. read uicr -> nrfjprog --readuicr app.uicr
5. both .uicr files should be same if your app is not writing anything to UICR

Ok, but I don`t think that our application is writing to the UICR registers. How can I clarify, if there is any overlapping address?

Hello, I posted my mergerhex command in one of the comments of Aryan answers. Regards, BTprogrammer

Seems like you have an overlapping addresses in the S120_softdevice.hex and application.hex. Is your application writing to UICR? It should not matter with the order of the hex while merging unless there is some conflict.

Hello again,

I think I found my mistake. It seems that the order of how to merge the .hex files assumes a role:

mergehex.exe -m application.hex s120_softdevice.hex -o complete.hex --> works fine with drag and drop feature

mergehex.exe -m s120_softdevice.hex application.hex -o complete.hex --> doesn`t work with drag and drop feature

Now I`m able to use the drag and drop feature. Thanks for support.

Could you post the exact cmd you used for mergehex?

Good morning,

What do you mean with "role"? The BLE role? My application runs as an peripheral.

Yes, If the softdevice and my application .hex files are programmed separately with nrfjprog, it works. I used the following commands:

nrfjprog.exe --program s120_softdevice.hex --chiperase
nrfjprog.exe --program application.hex
nrfjprog.exe --run

But if I use the mass storage drag and drop feature, it seems as the device doesnt even start running. So I dont know how to debug the application when using the drag and drop feature.

What is the role of your application? if you program softdevice and application separately with nrfjprog does your application work? Are you able to debug your application, if yes, then find out where it fails.
