source file, heard file path, sdk_config...still a "Undefined symbol nrfx_spim_init" error

[SuirenEngineer]

hi 

I have written a driver for an SPI sensor, and it works perfect in a nrfx_spim example project.

But when I tried to add this driver to a ble custom project, errors(Undefined symbol nrfx_spim_init, Undefined symbol nrfx_spim_xfer) appear.

"linking..."

''.\_build\nrf52840_xxaa.axf: Error: L6218E: Undefined symbol nrfx_spim_init (referred from iim42351.o)."...

Blow are my settings. I add nrfx_spim.c to nRF_Drivers group, Enable "NRFX_SPIM_ENABLED" ,"NRFX_SPIM3_ENABLED", and make sure the header file path is included.

but still the nrfx_spim.c cannot be compiled correctly(I looked into the "listening" result of translation of nrfx_spim.c and found it ended before intering nrfx_spim.h). 

Anyting other I missed?

Thanks.

 Probably something missing from the sdk_config file. Try to diff the two files and see if there is anything relevant that is different.

Thank you!

After removing NRFX_SPI related settings, no linking errors appear.

Seting these items to 0 is not enough, you should remove them from the sdk_config.h file.
