I have an overlay configuration:
/ { spi3: &spi3 { status = "okay"; pinctrl-0 = <&spi3_default>; pinctrl-1 = <&spi3_sleep>; pinctrl-names = "default", "sleep"; cs-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>; max30001: max30001@0 { compatible = "maxim,max30001"; reg = <0x0>; spi-max-frequency = <1000000>; intb-gpios = <&gpio1 9 GPIO_ACTIVE_LOW>; rtor-enabled; ecg-enabled; bioz-enabled; ecg-gain = <3>; ecg-invert; }; }; };
However, I keep getting the following error: devicetree error: /Users/aa/code/nrf/untitled_2/nrf52840dk_nrf52840.overlay:3 (column 11): parse error: expected node or property name Is there something wrong with my configuration? Thank you.
