昨天在emuelec dtb里面加了这一段 似乎不起作用。
serial@ffd24000 {
compatible = "amlogic, meson-uart";
reg = <0x0 0xffd24000 0x0 0x18>;
interrupts = <0x0 0x1a 0x1>;
status = "okay";
clocks = <0x15 0x2 0x2f>;
clock-names = "clk_uart", "clk_gate";
fifosize = <0x80>;
pinctrl-names = "default";
pinctrl-0 = <0x25>;
phandle = <0xbd>;
bluetooth {
compatible = "realtek,rtl8723bs-bt";
};
};
是否需要把这一段删除?抑或是linux 4.9.269 不支持这个驱动?
bt-dev {
compatible = "amlogic, bt-dev";
dev_name = "bt-dev";
status = "okay";
gpio_reset = <0x28 0x53 0x0>;
gpio_hostwake = <0x28 0x55 0x0>;
};
最后还是改回用启动脚本的方式了。 |
