Dear Nordic team.
I am a beginner learning to connect a SPI devices with nRF54L15-DK but the program always reports errors. Here are my related codes:
nrf54l15dk_nrf54l15_cpuapp.overlay:
/ {
chosen {
nordic,nus-uart = &uart20;
};
reserved-memory {
#address-cells = <1>;
#size-cells = <1>;
ranges;
};
};
&spi22 {
status = "okay";
compatible = "nordic,nrf-spim";
pinctrl-0 = <&spi22_default>;
pinctrl-1 = <&spi22_sleep>;
pinctrl-names = "default", "sleep";
max-frequency = <DT_FREQ_M(8)>;
my_spi_scr: my_spi_scr@0{
compatible = "spidev";
reg = <0>;
spi-max-frequency = <DT_FREQ_M(8)>;
cs-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>;
status = "okay";
label = "MYSPISCREEN";
};
};
&pinctrl {
spi22_default: spi22_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, 3)>, <NRF_PSEL(SPIM_MOSI, 0, 2)>;
};
};
spi22_sleep: spi22_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, 3)>, <NRF_PSEL(SPIM_MOSI, 0, 2)>;
};
};
};

static const struct spi_dt_spec scr_spi = SPI_DT_SPEC_GET(SPI22_NODE, SPI_WORD_SET(8), 0); // <= the code where the error is reported
Error Content:
I have tried many times to fix this error but never make sense. I will be appreciate if someone can help.
