memory 配置中有给用户盘预留空间，格式化以后却显示用户盘空间为0

请修改mcu\fs\fat\src\Rtfcore.c中以下部分，

 #ifndef __FS_CARD_DOWNLOAD__

          // Always ount free clusters right away

          // 1. at system init

          // 2. at FS_LockFAT(FS_REMOUNT_ENUM) or FS_TestMSDC, FS_DEVICE_COUNT_FREE_CLUSTER will be set before call MountRemovableDevice().

          if ((kal_query_systemInit() == KAL_TRUE) ||

              

              (Drive->Dev->DevData.Reserved & FS_DEVICE_COUNT_FREE_CLUSTER))  {

             BatchCountFreeClusters(Drive);

          }

 #endif

 修改为：

 #ifndef __FS_CARD_DOWNLOAD__

          // Always ount free clusters right away

          // 1. at system init

          // 2. at FS_LockFAT(FS_REMOUNT_ENUM) or FS_TestMSDC, FS_DEVICE_COUNT_FREE_CLUSTER will be set before call MountRemovableDevice().

          if ((kal_query_systemInit() == KAL_TRUE) ||

              (Drive->Dev->DeviceNumber == gFS_DeviceNumOfSYSDRV) ||   //添加这样一行

              (Drive->Dev->DevData.Reserved & FS_DEVICE_COUNT_FREE_CLUSTER))  {

             BatchCountFreeClusters(Drive);

          }

 #endif
