I need to add a SPI node in overlay file to support st3911b on a our board with nRF52840:
&pinctrl {
spi_master_default: spi_master_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, 11)>,
<NRF_PSEL(SPIM_MOSI, 0, 21)>,
<NRF_PSEL(SPIM_MISO, 0, 19)>;
};
};
spi_master_sleep: spi_master_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 0, 11)>,
<NRF_PSEL(SPIM_MOSI, 0, 21)>,
<NRF_PSEL(SPIM_MISO, 0, 19)>;
low-power-enable;
};
};
};
&spi1 {
compatible = "nordic,nrf-spim";
status = "okay";
cs-gpios = <&gpio0 20 GPIO_ACTIVE_LOW>;
pinctrl-0 = <&spi_master_default>;
pinctrl-1 = <&spi_master_sleep>;
pinctrl-names = "default", "sleep";
spi_3911b: spi_3911b@0 {
compatible = "spi-device";
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
spi-max-frequency = <4000000>;
label = "SPI_3911B";
};
};
I always received error: '__device_dts_ord_DT_N_S_soc_S_spi_40004000_S_spi_3911b_0_P_cs_gpios_IDX_0_PH_ORD' undeclared (first use in this function) during compiling.
Please help,
Mark,
