ERROR nrfx_spim_init &nrfx_spim_xfer_dcx

[mahi354]

Hello sir, I'm now working on the nrf52840 and am having trouble with the sdk config.
Initially, I indicated that I was working with spim3 and that it was functioning OK; I am able to use spim3 to work with an LCD.
But, when I enable twi0, twi1, and the spim3in config file, I receive these errors; however, if I disable twi1, I do not receive any errors.

Output/Release/Obj/ble_app_hrs_freertos_pca10056_s140/st7789h2_driver.o: in function `spim3_init':

undefined reference to `nrfx_spim_init'

undefined reference to `nrfx_spim_xfer_dcx'

undefined reference to `nrfx_spim_xfer_dcx'

In my case, I wish to use four interfaces: twi0, twi1, spim2, and spim3. Is that even possible?

i am sharing the sdk_con8015.sdk_config.txtfig file please verify , i am not getting what's the wrong i did.

Hi,

It should be possible to use TWI0, TWI1, SPIM2, and SPIM3 together, you can see which peripheral instances overlap by looking at the ones with same Base address in Instantiation documentation.

I can't see any obvious issues in your sdk_config.h file, can you post the full project for use to reproduce/debug the issue? If you do not want to post your project in public, I can convert the ticket to a private one.

Best regards,
Jørgen

Thank you for your response, sir.
When I debug the code, I discovered the NRFX SPIM ENABLED macro, which I set in the sdk config file. However, the nrfx spim.c file shows disabled, and when I examine the macro definition, it opens the apply old config.h file instead of the sdk config file.

what are my options for resolving the problem?

Thank you very much.

If you do not use the legacy SPI driver API, I would recommend you to completely remove the entire config section from your sdk_config.h file:

// <e> SPI_ENABLED - nrf_drv_spi - SPI/SPIM peripheral driver - legacy layer
//==========================================================
#ifndef SPI_ENABLED
#define SPI_ENABLED 1
#endif

// </e>

// </e>

These configs will overwrite the NRFX_SPI/NRFX_SPIM configs in apply_old_config.h just by being defined (regardless of if they are set or not). SPIM3 is not supported in the legacy driver.
