As an update incase anyone else struggles with the same issue. The problem seem to have been the .dts file. The one for nrf52840 devkit that is included in ncs, nrf52840_pca10056 states the following:

&spi0 {
	compatible = "nordic,nrf-spi";
	/* Cannot be used together with i2c0. */
	status = "okay";
	sck-pin = <27>;
	mosi-pin = <26>;
	miso-pin = <29>;
};

Note the "compatible" filed only states nrf-spi and NOT nrf-spim. This resulted in not all files being generated, thus the error when trying to build .

Adding compatible = "nrf-spim" at spi0,sp1 and spi2 fixed this. The same thing was needed for i2c, changing "nrf-twi" to "nrf-twim".

Seems like it does

Sure thing, here you go. It seems like it is some silly configuration I have missed, the question is just what. Would be great i I could get another set of eyes on if.

Could you double check that you are on NCS v1.2.0 ?

git status should return the following:

C:\ncs\nrf>git status
HEAD detached at v1.2.0

C:\ncs\zephyr>git status
HEAD detached at ff214d637e

Make sure that you have board nrf52840_pca10056 selected

Does this .hex file work on your DK?

devzone.nordicsemi.com/.../zephyr.hex

If it's still not working, could you zip and upload your spi project build folder ?

I tried loading it up and I still get the same error:

*** Booting Zephyr OS build v2.1.99-ncs1  ***
SPIM Example
Could not get SPI_0 device

And then the device just keeps restarting. I opened your example using file -> open nrf connect sdk project and selection CMakeLists.txt in the example. Then I built and uploaded via SES. Is there anything except i2c0 that can come in conflict with spi0?

This is my config:

Works fine here when I test with NCS v1.2.0

Here is the project I used for testing:

Hi, thank you for your answer.

My .overlay is empty but my nrf52840_pca10056.dts has the following:

&spi0 {
	compatible = "nordic,nrf-spi";
	/* Cannot be used together with i2c0. */
	status = "okay";
	sck-pin = <27>;
	mosi-pin = <26>;
	miso-pin = <29>;
};

And my .conf has the following:

CONFIG_NRFX_SPIM=y
CONFIG_NRFX_SPIM0=y

The strangest thing is, it's only seems like its SPI0 that isn't working, I've managed to get both SPI1 & SPI3 to work with the same settings. But once I try SPI0, the device bind fails and the processor hard faults.

How does your nrf52840_pca10056.overlay file look like? Try adding something like this to the file:

&spi0 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	sck-pin = <3>;
	mosi-pin = <4>;
	miso-pin = <28>;
	cs-gpios = <&gpio0 29 0>, <&gpio0 30 0>;
};

In .conf, you need something like this:

CONFIG_SPI=y
CONFIG_SPI_NRFX=y
CONFIG_SPI_0=y
CONFIG_SPI_0_NRF_SPIM=y

Update: I managed to get it to build by only enabling "SPIM_0" and skipping "SPI_0". However, now everything crashes as soon as i run device_get_binding("SPI_0");
