如何实现开机自动检测T卡是否存在并将彩信存储到T卡

1. MMI_MMS_STORAGE_IN_CARD_PREFER 

  

 2. srv_mms_read_nvram_settingsTT 

 #ifdef __MMI_MMS_MEMORY_CARD_STORAGE_SUPPORT__ 

 #ifdef MMI_MMS_STORAGE_IN_CARD_PREFER 

  if(mmi_fmgr_is_drive_accessible((S8)MMI_CARD_DRV)) 

   { 

    nvram_mms_prefer_storage = E_PREFER_STORAGE_MODE_CARD; 

   } 

   

  else 

 #else 

   { 

    ReadValue(NVRAM_SETTING_PREFER_MMS_STORAGE_MODE, &nvram_mms_prefer_storage, DS_BYTE,

 &error); 

   } 

   

 #endif 

   

     if (nvram_mms_prefer_storage == 0xFF) 

     { 

         nvram_mms_prefer_storage = E_PREFER_STORAGE_MODE_PHONE; 

     }
