core_cm4.h not found

Johan Gasslander over 8 years ago

When switching to nRF52_SDK_11, the compiler does not find core_cm4.h which is found in components/toolchain/CMSIS/Include.

I get this when compiling

nRF5_SDK_11.0.0_89a8197/components/device/nrf52.h:137:130: fatal error: core_cm4.h: No such file or directory

Depending on your IDE you can solve this a couple of ways. The most direct is adding a path to the CMSIS include directory. An example from an IAR project I have looks like this: "$TOOLKIT_DIR$\CMSIS\Include". Some IDE's also have controls to enable use of CMSIS. IAR has a check box you can turn on to use CMSIS. I don't believe Keil has a similar feature.

Which IDE are you using? Keil, Eclipse, IAR or CrossWorks?
