SPIM3 on nRF52840 and SDK17.0.2

[PW]

Hello.

I've got problem with properly build example SPIM3 code. I took blinky example, added code from nrfx_spim example, set SPIM3 in sdk_config.h, add nrfx_spim to project and ...... nrfx_spim_init(...) is undefined symbol. I have no idea why. My project settings are the same with nrfx_spim example. Attachement code is only test code. Original code is much bigger but the situation with nrfx_spim_init(...) is the same.

Best regards

It's was solved. SPI_ENABLED section in sdk_config.h has to be commented. SPI_ENABLED 0 is not enough.  After that, code inside nrfx_spim.c is active in project. Strange...

I am happy to hear that you were able to resolve your issue!

This is correct, because apply_old_config will overwrite any NRFX_*_ENABLED if a *_ENABLED is left defined, therefore it needs to be commented out or removed completely.
This feature is in place to ensure backwards compatibility, but I have seen that this has caused confusion for multiple forum goers, and I have reported this for review internally.
