器件型号：J722SXH01EVM 工具/软件：
您好的团队、
linux_sdk 版本： ti-processor-sdk-linux-adas-j722s-evm-11_00_00_08
我不熟悉器件树和 Linux。 我将尝试从 u-boot 切换 j722s-EVM 板上的 USER_LED1。
我在 ti-u-boot-2025.01+git/dts/上游/ src /arm64/ti/k3-j722s-evm.dts 中进行了以下更改
/ {
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";
};
以下是我的 u-boot 日志：
