楼主
AP6335的wifi是OK的,但打开蓝牙时出错,串口的信息如下:

初始化AP6335时,看到的串口信息如下:
[ 1.003292] [BT_RFKILL]: Enter rfkill_rk_init
[ 1.003394] [BT_RFKILL]: Enter rfkill_rk_probe
[ 1.003413] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: uart_rts_gpios = 147.
[ 1.003430] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: BT,power_gpio = 157.
[ 1.003453] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: BT,wake_gpio = 154.
[ 1.003468] [BT_RFKILL]: bluetooth_platdata_parse_dt: get property: BT,wake_host_irq = 159.
[ 1.003498] [BT_RFKILL]: init gpio

[ 1.003614] [BT_RFKILL]: setup rfkill
[ 1.003686] [BT_RFKILL]: ap6335 device registered.
从上面的信息看,AP6335的蓝牙初始化是正常的,各位帮忙看看问题出在什么地方。
dts的配置如下:
wireless-bluetooth {
compatible = "bluetooth-platdata";
uart_rts_gpios = <&gpio4 GPIO_C3 GPIO_ACTIVE_LOW>;
pinctrl-names = "default","rts_gpio";
pinctrl-0 = <&uart0_rts>;
pinctrl-1 = <&uart0_rts_gpio>;
BT,power_gpio = <&gpio4 GPIO_D5 GPIO_ACTIVE_HIGH>;
BT,wake_gpio = <&gpio4 GPIO_D2 GPIO_ACTIVE_HIGH>;
BT,wake_host_irq = <&gpio4 GPIO_D7 GPIO_ACTIVE_LOW>;
status = "okay";
};
