工具与软件：
您好、TI：
我们正在尝试使用 AM62A3处理器配置 ADV7511w。 我们正在使用最新版本 10.08v 和以下是设备树配置:
&dss {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_dss0_pins_default>;
};
hdmi0: connector-hdmi {
compatible = "hdmi-connector";
label = "hdmi";
type = "a";
port {
hdmi_connector_in: endpoint {
remote-endpoint = <&adv7511w_out>;
};
};
};
&dss_ports {
/* VP2: DPI Output */
hdmi0_dss: port@1 {
reg = <1>;
dpi1_out: endpoint {
remote-endpoint = <&adv7511w_in>;
};
};
};
adv7511w: adv7511w@39 {
compatible = "adi,adv7511w";
reg = <0x39>, <0x66>;
reg-names = "main", "edid";
adi,input-depth = <8>;
adi,input-colorspace = "rgb";
adi,input-clock = "1x";
// adi,input-style = <3>;
// adi,input-justification = "right";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
adv7511w_in: endpoint {
remote-endpoint = <&dpi1_out>;
};
};
port@1 {
reg = <1>;
adv7511w_out: endpoint {
remote-endpoint = <&hdmi_connector_in>;
};
};
};
};
在显示屏上进行流式传输时出现以下错误：
tidss 电桥原子检查：连接的显示屏中没有 BUS_Formats
以下是 dmesg 日志供您参考:
