I'm closing this thread and opening a new one for the TWI/SPI issue since the answer on how to eliminate "Wrong configuration" has been given.

It seems that if I don't initialize SPI (by commenting out nrf_drv_spi_init() or eliminating SPI altogether) then my FW is stuck in: while (twi_transfer(p_twi, &p_cb->error, &p_cb->bytes_transferred, (uint8_t *)p_data, length, no_stop))
{} of twi_tx_start_transfer() when calling my first I2C transaction. Any idea why?

What do you mean by "still does not run properly"? Can you give me more details?

To make my project work, I have the file nrf_drv_spi.c included in the build and I call nrf_drv_spi_init() with dummy pins (0) for the SPI peripheral. If I comment out nrf_drv_spi_init() but leave nrf_drv_spi.c with #define SPI0_ENABLED 1, my project builds but does not run properly. Similarly, if I remove nrf_drv_spi.c (per your suggestion) with #define SPI0_ENABLED 0, my project builds (I don't get the "Wrong configuration" error this time) but still does not run properly. Please advise.

Hi,

If you have a look at the error on line #35 in nrf_drv_spi.c, you can see that this will only trigger if SPI and SPIM are not in use. Maybe it will help to remove nrf_drv_spi.c from your project?
