RE: nRF52810 and SPIM configuration

OK, thanks - so the legacy stuff, when set, overrides the other stuff. I think I'll stick with commenting out legacy stuff in my sdk_config for now; I don't want to mess up other things by removing apply_old_config.h.

Hello,

I would say that you are pretty much spot on:

"On investigation, it looks almost as if NRFX_SPIM0_ENABLED is getting undefined somewhere."

If you search in your project, you should fine a file called "apply_old_config.h" which does exactly this.

I believe it is included in most projects for porting reasons. However, it is quite confusing when you start with SDK15.

The solution is to:

1. Either remove all legacy defines from sdk_config.h. Make sure to not remove the defines that doesn't have an NRFX implementation, that you want to use.

2. remove the apply_old_config.h file (make sure that the project doesn't include it). It is included from the file "nrfx_glue.h".

If you look at the file, apply_old_config.h, you will understand what it does, and why you get the behavior that you see.

Best regards,

Edvin
