Please help me to eliminate the error : "cannot open source input file "nrf_erratas.h": No such file or directory" for nrf51422 for nrf 51(12.3) sdk in keil version 5
Can you try to rename \nRF5_SDK_12.3.0_d7731ad\components\device\compiler_abstraction.h to something else? (Example: compiler_abstraction_something_else.h)
Hi Kenneth, I did what you told, but still error exists. I have one more doubt - in which path sdk should be stored
There is no specific requirements to the path the SDK v12.3 should be installed.
Make sure to first open Keil and open Pack Installer and remove all instances of MDK 8.28.0 and newer (remove both from DeviceFamilyPack and DeviceFamilyPack_Nordic).
Then go to http://developer.nordicsemi.com/nRF5_SDK/pieces/nRF_DeviceFamilyPack/ and install Family pack of 8.11.1.
Now you should be able to open any SDKv12.3 Keil projects, though projects you have already open previous you need to unzip again.
