Tool/software:
Hi team,
linux_sdk version: ti-processor-sdk-linux-adas-j722s-evm-11_00_00_08
I'm new to device tree and linux. I'm trying switch ON user_led1 on j722s-evm board from u-boot.
I've made following changes in ti-u-boot-2025.01+git/dts/upstream/src/arm64/ti/k3-j722s-evm.dts
/ {
led0: user_led0 {
compatible = "gpio-leds";
pinctrl-names = "default";
pinctrl-0 = <&main_led_pins_default>;
led_0 {
label = "user-led0";
gpios = <&main_gpio1 49 GPIO_ACTIVE_HIGH>;
default-state = "on";
};
};
};
&main_pmx0 {
main_led_pins_default: main-led-default-pins { /* TARUN changes */
pinctrl-single,pins = <
J722S_IOPAD(0x244, PIN_OUTPUT, 7) /* (A24) GPIO1_49 */
>;
};
};
&main_gpio1 {
status = "okay";
};
Below is my u-boot logs:
