Hi,

What example are you trying to build? If it is an example already in the SDK, have you made any changes to it? How are you building the example?

Best regards,

Marte

Hi,

This is related to a bug in the MDK included in nRF5 SDK v17.1.0. There is a note regarding this in the SDK release notes with a workaround:

Note for IAR 8 users:

When using IAR 8, you must apply the following workaround in the MDK:

- Apply a patch to modules/nrfx/mdk/compiler_abstraction.h at line 140
(fix the '__ALIGN()' macro definition): use the argument 'n' in the macro expansion instead of 'x'.

Another option is to download and use the latest MDK version, nRF MDK v8.42.0, where this has been fixed. You can find this by going to the following link: nRF MDK Downloads.

Best regards,

Marte
