IAR Device Options "NordicSemi" and "NordicSemiconductor"?

[import11]

We have two developers running the same version of IAR and the SDK and one of them has different device options under the project options. My IAR project works with NordicSemi > nRF51 > NordicSemi nRF51422-QFAC. When he builds and attempts to debug there are all kinds of run issues. Is there a different version of something that we are running that is causing the discrepancy?

His works fine if he selects the NordicSemiconductor > nRF51422-xxAC option as shown in the attached image.

Which chip version are you using? The QFAA and QFAB version have only 16KB RAM. The stack is placed in the top of the RAM (and grow downward). If you are using QFAA or QFAB and compile for the QFAA version (which have 32KB RAM), the stack will be placed outside of the actual RAM area.

Sorry, there was a typo in the original post. The part we are using is the QFAC. We both have selected the AC option, but in the image there are two options for Nordic chips: NordicSemi and NordicSemiconductor. I didn't have both options and realized that was due to not installing the MDK. The xxAC versions are from the MDK and are what need to be selected.

So it does not work with the device from the NordicSemi catalog, but with the NordicSemiconductor catalog?

That is correct. For whatever reason it worked fine for me using the NordicSemi catalog, but not for my co-worker. We just found out this morning that we should be using the NordicSemiconductor catalog as that is what is provided by the MDK. NordicSemi catalog is provided by IAR.
