Hi Einar,

I did use the "mergehex -- version" command to double check which version of the nRF Command Line Tools I actually got and the response to this command was: mergehex version: 10.12.2.

Hi Jacek,

I see. Can you share the hex files you used as input as well as the resulting output file? You can create a private ticket for it if you do not want to share them on this public forum.

Hi Einar,

Herewith are the two hex files that I used as an input:

nrf9160dk_asset_tracker_ltem_2021-03-01_8e8c6089.hexnrf9160dk_asset_tracker_nbiot_2021-03-01_8e8c6089.hex

but I can't see any resulting output file.

I attach a relevant screen shot:

Hi Jacek,

I am not sure I understand. The question here is about mergehex generating invalid outpuf files, right? Then i would need to know how you reproduce the issue, which files you merge (input to mergehex) and the output.

Hi Einar,

The problem is that I can't complete the process of updating the application firmware for my new nRF9160 DK, which I need to complete before I can start using this unit.

I was following the following steps, as per the instruction:

1. I did download the latest nRF9160 DK Application and Modem firmware from the "nRF9160 DK Downloads" page and extracted it to a folder on my PC.

2. I opened the "nRF Connect for Desktop" and I launched "nRF Connect Programmer".

3. I set the Prog/Debug (SW5) on the nRF9160 DK to nRF91, as instructed.

4. I did connect the nRF9160 DK to my PC and I turned it on. I saw that in the Navigation Bar "No Devices available" changed to " Select Device".

5. I clicked "Select Device" and I selected my device from the dropdown list. I identified the nRF91605611.nrf9160dk_asset_tracker_ltem_2021-03-01_8e8c6089.hex DK by the fact that it had 3 COM ports.

6. I then saw the message: "Device is connected. Press 'Read' button to read the memory".

7. I then clicked "Add Hex files" in the file pane on the right and I selected "Browse".

8. I navigated to the subfolder of the folder where I extracted the nRF9160 DK firmware and I selected these two hex files:

nRF9160dk_asset_tracker_nbiot_2021-03-01_8e8c6089.hex  and 

nRF9160dk_asset_tracker_Item_2021-03-01_8e8c6089.hex

5611.nrf9160dk_asset_tracker_ltem_2021-03-01_8e8c6089.hex

and

1423.nrf9160dk_asset_tracker_nbiot_2021-03-01_8e8c6089.hex

9. As soon as I added the second hex file to the list of hex files to be added, I saw the message:

"Overlapping Files. Some of the hex files have overlapping data".

10. I was able to successfully write into my nRF9160 DK each of these two hex files on its own by clicking the "Erase & Write" button but not when I tried to add these two hex files to my nRF9160 DK at the same time, as the error message: "Some of the hex files have overlapping data" appeared each time I tried.

What shall I do to successfully complete the process of updating the application firmware on my new nRF9160 DK, so that I could start using it?

I attach these two hex files as a reference.

Regards,

Jacek
