Latest nrfjprog on OS X - mismatched J-Link DLL

Mahesh Venkitachalam

With the latest nrfjprog from Nordic and latest J-Link software from Segger, I am still getting the error below.

$ nrfjprog -v
ERROR: JLinkARM DLL version used is too old for nrfjprog. Please update it by
ERROR: installing the latest JLinkARM package from Segger webpage.
klaatu:armgcc mahesh$ JLinkExe 
SEGGER J-Link Commander V5.12d (Compiled Apr 26 2016 19:22:21)
DLL version V5.12d, compiled Apr 26 2016 19:22:15
...

I am using OS X 10.9.5.

Any ideas on what might be wrong?

Thanks

    Hi Mahesh,

    This problem occurs because we were assuming SEGGER was simply replacing the .dylib file in their installed folder, as was the case earlier. In release 5.12e, which i was testing with, they do not replace the .dylib file, but simply add the new ones. We will have to handle this properly in our own tool and make a new release, but to fix it for now, you can simply delete all the "old" .dylib files in /Applications/SEGGER/JLink, you need only ...5.12.5.dylib and the ...5.dylib; or uninstall the SEGGER software, and re-install only the latest.

    Let me know if this doesnt solve your problem.
