君正X1000 PWM4蜂鸣器该如何调试？
我kernel配置如下：
Device Drivers  --->
    Input device support  --->
        *   Miscellaneous devices  --->
        *    PWM beeper support (NEW)

->Device Drivers
    -> Pulse-Width Modulation (PWM) Support (PWM [=y])
        --- Pulse-Width Modulation (PWM) Support
        *   JZPWM support for LED or Beeper drivers
        *   JZ PWM driver 
        *** JZ PWM function pinselect ***
         *    GPIO Port pwm0       
         *    GPIO Port pwm4

应用上需要什么操作？大神们方便帮忙看下，非常感谢！
