Hi Nordic,
I am using nrf Connected SDK 1.7 on windows 10, coding with nrf connect extension for vscode.
I created a custom board from nrf5340 SoC and added a node as a device on SPI bus in custom board dts file, a error pops up when I put mouse pointer on the node name. it said "Only spi nodes accepted in /soc/peripheral@50000000/spi@b000/. /soc/peripheral@50000000/spi@b000/ads129xr@0/"
The error shows as in the picture yellow box below.
the project can build without any error.
the device tree fragment as below:
&spi2 {
compatible = "nordic,nrf-spim";
status = "okay";
sck-pin = < 12 >;
miso-pin = < 14 >;
mosi-pin = < 18 >;
cs-gpios = < &gpio0 15 GPIO_ACTIVE_LOW >;
ads129xr0: ads129xr@0 {
compatible = "ti,ads129xr";
label = "ADS129xR";
reg = <0>;
status = "okay";
spi-max-frequency = <4000000>;
pwdn-gpios = <&gpio0 10 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpio0 11 GPIO_ACTIVE_LOW>;
drdy-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>;
start-gpios = <&gpio0 17 GPIO_ACTIVE_HIGH>;
};
};
