AIO-3288C 烧写官方的UBUNTU固件蓝牙无法使用
如题， AIO-3288C 无论是烧写ubuntu16，还是18，蓝牙均无法使用，打开bluetooth device，所有按钮均是灰色点不了。查看启动日志发现蓝牙启动时报错：[ 7.211372] : bluetooth_platdata_parse_dt: get property: uart_rts_gpios = 139.
[ 7.211396] : bluetooth_platdata_parse_dt: get property: BT,reset_gpio = 149.
[ 7.211412] : bluetooth_platdata_parse_dt: get property: BT,wake_gpio = 146.

[ 7.211430] : bluetooth_platdata_parse_dt: clk_get failed!!!.
进入系统使用命令：
root@firefly:~# hciconfig -a
hci0: Type: PrimaryBus: UART

使用如下命令：
root@firefly:~# hciconfig hci0 up
Can't init device hci0: Invalid request code (56)
root@firefly:~# hciconfig hci0 reset
Can't init device hci0: Invalid request code (56)
请问下这个如何解决啊
