some of hex files have overlapping data in nrf connect

Hi Jacek,

The problem you are describing is that you cannot program two hex files that overlap, and that is expected and how it must be. You are trying to program two examples that reside in the same area at one, and that will never work. Please make a new question if you need more assistance on this as it is not related to the original topic in this thread.

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 nRF9160devzone.nordicsemi.com/.../5611.nrf9160dk_5F00_asset_5F00_tracker_5F00_ltem_5F00_2021_2D00_03_2D00_01_5F00_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

devzone.nordicsemi.com/.../5611.nrf9160dk_5F00_asset_5F00_tracker_5F00_ltem_5F00_2021_2D00_03_2D00_01_5F00_8e8c6089.hex

and

devzone.nordicsemi.com/.../1423.nrf9160dk_5F00_asset_5F00_tracker_5F00_nbiot_5F00_2021_2D00_03_2D00_01_5F00_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

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,

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

devzone.nordicsemi.com/.../nrf9160dk_5F00_asset_5F00_tracker_5F00_ltem_5F00_2021_2D00_03_2D00_01_5F00_8e8c6089.hex devzone.nordicsemi.com/.../nrf9160dk_5F00_asset_5F00_tracker_5F00_nbiot_5F00_2021_2D00_03_2D00_01_5F00_8e8c6089.hex

but I can't see any resulting output file.

I attach a relevant screen shot:

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,

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,

There was some problems with publishing the new nRF Command LIne Tools distribution. Can you double check that you actually got 10.12.2 and not 10.12.1 by using mergehex --version?

Hi Einar,

Thanks for your reply from 2 days ago.

I did download and install on my PC the additional release of nRF Command Line Tools (10.12.2) one hour ago but the problem with "the hex files having overlapping data in nrf connect" still persists.

I am trying to update the application firmware on my nRF9160 DK.

Regards,

Jacek

Hi Jacek,

The fix for this issue has been pulled in, and an additional release of nRF Command Line Tools is being prepared. This will be 10.12.2 and will be out any time now.

Hi,

I experienced the problem of hex files having overlapping data in the nrf connect while using the latest mergehex 10.12.1.

I followed your advice and I tried to revert to an older version of the nRF Command Line Tools, namely to

10.12.0 and 10.11.1 but without success. The problem still persisted.

Which older version of the nRF Command Line Tools shall I revert to to overcome this problem?

When will the upcoming release of the latest mergerhex (10.13.0), that will have this problem fixed, be available?

Regards,

Jacek

Hi,

There is an issue with the latest mergehex (10.12.1) where it generates corrupt hex files. This will be fixed in the upcoming release (10.13.0). In the meantime, either revert to an older version of nRF Command Line Tools (or avoid using it).
