How to identify SDK version?

[Gerry Ortoli]

I'm attempting to troubleshoot problems between dev teams. One team is having some issues & I notice that their binary is slightly larger when built from exactly the same source. It seems to run OK but I'm uncomfortable with that difference.

First, what is the best way to determine the version of the Nordic SDK that someone has installed into their Keil software? Right now all I can think of is looking at the release_notes.txt file in the :\Keil\ARM\Device\Nordic\Documentation folder. For example, SDK v4.4.1.31827 is identified in that file as 4.4.1.

Second, is there any way to tell what version of the SDK was used to build a binary file? Do the hex or axf files contain an SDK "signature"? That would be awesome.

Lastly, I believe it is most important to mind the versions of SDK, SoftDevice, and Nordic chip used together. I believe that the Keil & J-Link software versions are not as important. Are these good assumptions or should I be looking at those differences as well?

Thanks!

Hi there,

@. It seems to run OK but I'm uncomfortable with that difference.

Did you also compare the .uvproj files? It could be that the compiler/linker options are different.

@Do the hex or axf files contain an SDK "signature"?

Unfortunately, there is no way to find out the SDK version from the axf file,

@I believe that the Keil & J-Link software versions are not as important. Are these good assumptions or should I be looking at those differences as well?

Keil version is also important. A different compiler (in this case armcc) version may or may not have an impact on the final hex file. The J-Link software versions are not important.

Thanks for the quick response.
