merge hex - area overlap

Thank you so much for the release of mergehex 10.12.2. I have been chasing this issue for days, finally coming to the conclusion that mergehex was producing a merged hex file with a defect in it. Once I was satisfied that mergehex had a defect I decided to search the DevZone and found this thread. Within minutes I had downloaded and installed nRF Command Line Tools 10.12.2 and produced a correct hex file. Thanks again.

Hi,

No, unfortunately not. However, we decided to pull in the mergehex fix and it will be part of a 10.12.2 release of nRF Command Line Tools that is about to go out the door. It is not out yet, but should be out any day now (possibly even today). When it happens, you can find it here.

Hi Enar,

Is the Command Line Tools (10.13.x) resealed?

Hi,

I was wrong. This is an issue with mergehex, though nrfjprog does not complain. It will be fixed in the next release of nRF Command Line tools (10.13.0).

Yes, I agree. I have created a bug report for it. I cannot say when it will be fixed, though.

I tried to flash the merged hex file with nrfjprog and it works, so I think the main issue is related to nrfConnect!
nrfjprog version: 10.12.1
JLinkARM.dll version: 6.88c

Thank you for your support, I suppose this is a bug of nRF Connect!

Hi,

Now I see. I have the same issue with nRF Connect Programmer here. I do not have any problems with the merged hex file in any other tools, so I suspect there is an issue with nRF Connect programmer. Not sure what it is though, but I will ask the developers to have a look at it.

The point is that if I try to load the merged file (both the one I generated myself and you attached here) into nrfConnect I get the same result.

I am using nRF Connect v3.6.1 - Programmer

mergehex version: 10.12.1

[quote userid="7377" url="~/f/nordic-q-a/70519/merge-hex---area-overlap/289516#289516"]Which version of nrf command line tools are you using?[/quote]

nrf5x-command-line-tools 10.12.1-0

I am using:
- nRF5_SDK_17.0.2_d674dde
- SEGGER Embedded Studio for ARM Release 5.32a Build 2020120901.44619

The strange thing is that if I use nrfConnect to merge the files (load and then save merged file) the generated hex file works! So I suppose I am missing something or the tools I use are different from the ones nRFConnect uses

Hi,

This is odd. The size of S1322 7.2.0 is 0x26000, so you should not get an overlap around 0x32c28 when merging the application hex and SoftDevice hex. I do not have any problem merging the two hex files you have attached:

mergehex.exe -m s132_nrf52_7.2.0_softdevice.hex ble_app.hex -o merged_app_sd.hex
Parsing input files.
Merging file "s132_nrf52_7.2.0_softdevice.hex" into output.
Merging file "ble_app.hex" into output.
Storing merged file.

Result: devzone.nordicsemi.com/.../4478.merged_5F00_app_5F00_sd.hex

It is also strange that you suddenly do not get complaints about overlap when also merging with settings.hex, in addition to the app and softdevice.

Which version of nrf command line tools are you using? What is the output of "mergehex --version"?
