6577平台cm36283（alsps）无法正常工作
打印log发现cm36283_ps_operate函数没有调用到，有没有哪位碰到过类似的情况。

这个是I2C的probe函数
if((err = hwmsen_attach(ID_PROXIMITY, &obj_ps)))
{
APS_ERR("attach fail = %d\n", err);
goto exit_sensor_obj_attach_fail;
}
if((err = hwmsen_attach(ID_LIGHT, &obj_als)))

APS_ERR("attach fail = %d\n", err);
goto exit_sensor_obj_attach_fail;
}
这两个函数开机时有跑到吗?
有没有出现fail?
这两个都跑过了，没有出现error，I2C_probe是ok的
你看看你用的是方式是中断模式还是轮询模式，要是中断模式，检查一下中断脚之类和中断方式的有没有配置好，要不把它先配置成轮询的方式先试试，在测试模式是用轮询去读数据的。
你最好是发串口的log上来，大家才好分析。
驱动代码有点小问题，跟供应商从新要了一份现在OK了
请问大虾是驱动代码的哪一块出了问题啊，我上次也出现了这种问题，但是就是没找到啊。测试模式下的值都正确就是实际的背光调节无反应。
我的是拨号的时候不能正常工作，自动调节背光没注意。
你是哪个平台
MTK啊
，我看你上面写的也是这个方案啊。
加个Q吧 共同交流 我的820486606
