The 'NCS-SPI-Master-Slave-Example' cannot be built

Question

Hello

I'm attempting to get the following example to work on a nRF5340DK using 'nRF Connect for VS Code' as a first attempt to use SPI on a Nordic controller:

- https://github.com/too1/ncs-spi-master-slave-example

I've started the project with 'basic/blinky' and copied the following code from the example to project:

- "nrf52840dk_nrf52840.overlay",

- "prj.conf" and

- "main.c"

I initially attempted to build with nRF Connect SDK v2.2.0 and subsequently on v2.1.1 (as per the "README.rst") and on both attempts this failed to build with the following errors :

C:\ncs\v2.1.1\zephyr\include\zephyr\drivers\pinctrl.h:89:10: error: 'PINCTRL_STATE_DT_N_S_soc_S_peripheral_50000000_S_spi_b000_PINCTRL_IDX_0_UPPER_TOKEN' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_peripheral_50000000_S_spi_a000_PINCTRL_IDX_0_UPPER_TOKEN'?

Looking at the following "zephyr.dts" extract below am I right to assume that spi@b000 (the slave SPI) has not been set up correctly so is offering the master instead? If so, how do I overcome this? (Has something in the background changed since the example has been saved?)

peripheral@50000000 {

#address-cells = < 0x1 >;

#size-cells = < 0x1 >;

ranges = < 0x0 0x50000000 0x10000000 >;

dcnf: dcnf@0 {

compatible = "nordic,nrf-dcnf";

reg = < 0x0 0x1000 >;

status = "okay";

};

.

spi4: arduino_spi: my_spi_master: spi@a000 {

compatible = "nordic,nrf-spim";

#address-cells = < 0x1 >;

#size-cells = < 0x0 >;

reg = < 0xa000 0x1000 >;

interrupts = < 0xa 0x1 >;

max-frequency = < 0x1e84800 >;

rx-delay-supported;

rx-delay = < 0x2 >;

status = "okay";

cs-gpios = < &gpio0 0xb 0x1 >;

pinctrl-0 = < &spi_master_default >;

pinctrl-1 = < &spi_master_sleep >;

pinctrl-names = "default", "sleep";

reg_my_spi_master: spi-dev-a@0 {

reg = < 0x0 >;

};

.

spi2: my_spi_slave: spi@b000 {

compatible = "nordic,nrf-spis";

#address-cells = < 0x1 >;

#size-cells = < 0x0 >;

reg = < 0xb000 0x1000 >;

interrupts = < 0xb 0x1 >;

max-frequency = < 0x7a1200 >;

status = "okay";

pinctrl-0 = < &spi2_default >;

pinctrl-1 = < &spi2_sleep >;

def-char = < 0x0 >;

};

I'll be grateful for any suggestions on how to overcome this build issue.

Thanks
