Great!

[quote user="Remosennhauser"]Is this on purpose that the nrf52_erratas.h is contained in the DeviceFamilyPack but not in the installer of the MDK V8.43.0 (nRF_MDK_8_43_0_IAR_BSDLicense.msi)?[/quote]

I see the same here. This looks like a bug with the installer. I have reported it to the team responsible for the MDK.

Hi Sigurd

Thanks for your answer.

Thanks for the explanation for ENABLE_APPROTECT. Sorry for this question, I haven't seen that it was already described in IN-142.

Yes, it worked with MDK 8.40.3, but not anymore with 8.43.0. When I compared the files between these MDK versions, I saw that the mentioned defines have been renamed. Could you send me your nrf52_erratas.h so that I can compare it with my version? Is that correct that the file nrf52_erratas.h is not part of the MDK?

Edit: 18.10.2021:

I just saw that I can download the device family pack V8.43.0 from the following site:
http://developer.nordicsemi.com/nRF5_SDK/pieces/nRF_DeviceFamilyPack/
This file contains the nrf52_erratas.h that differs to the one from the SDK V17.1.0. With the new file, the project compiles again.
Is this on purpose that the nrf52_erratas.h is contained in the DeviceFamilyPack but not in the installer of the MDK V8.43.0 (nRF_MDK_8_43_0_IAR_BSDLicense.msi)?

Best regards

Hi,

I was not able to reproduce this issue. Did it work for you when you used MDK v8.40.3 ?

[quote user=""]I have a further question regarding the define ENABLE_APPROTECT. It is not clear to me where and when this must be defined.
Should this be defined in the preprocessor of the project settings when I compile an image that is not intended for debugging?[/quote]

Correct. Set it like this:

Also, see https://infocenter.nordicsemi.com/pdf/in_142_v1.1.pdf

[quote user=""]Is there a sample project that shows how to use this define?[/quote]

There is no specific example for this. Just add the define in your project.
