Error: cannot open source input file "nrf_erratas.h": No such file or directory for nrf51 in keil version 5

I had the missing nrf_errats.h error when compiling newer example code to my project.

This notice for using Nordic Semiconductor::nRF_DeviceFamilyPack V8.32.1 is helpful for nRF51 SDK 12.3 projects on the PCA10028 board when adding newer examples to the project...

I am not a Nordic employee; I discovered this by poking and proding at the Run Time Environment and Target Options until I groked it. Older nRF_DeviceFamilyPacks (sometime prior to 8.30.2) did not contain the nrf_erratas.h and related files. Atempts to compile newer SDK examples with a system still configured to older DeviceFamilyPacks will error out for not finding the nrf_erratas file. At least IMO, the cleanest solution is to:

Use the Pack Installer to install the latest DeviceFamilyPack for your device and board,
Use the Select Software Packs to select only the latest version DFP (just installed),
Use the Project > Manage Run-Time Environment to reset the Device > Startup and Device > StartupConfig to the latest DFP version.
Go back and undo any hacks you made to the includes in the C/C++ build environment.

Note: These instructions are for the Keil IDE. Other IDE commands & structures will differ.

Have you tried to open a project that you have not previously opened?

Does it look like this:

In your case you should only need 8.11.1.

I could eliminate this error by including the file in options to target. Thanks for your time

The error is not eliminating. Please help me to get rid of this error

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.

Hi Kenneth, I did what you told, but still error exists. I have one more doubt - in which path sdk should be stored

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)

Best regards,
Kenneth
