android recovery mode下使用外置T卡升级修改方法

1、请您将Recovery.fstab (mediatek\config\[Project]\)中mount point 为/sdcard的项修改为如下内容：

/sdcard  vfat  /dev/block/mmcblk1p1 /dev/block/mmcblk1

2、请将alps/bootable/recovery/roots.cpp 下353-357行：

#else
                 } else if (!strcmp(mount_point, "/sdcard") && has_fat && strcmp(device, dev[FAT_INDEX])) {
                     device_volumes[num_volumes].device = strdup(dev[FAT_INDEX]);
                     device_volumes[num_volumes].device2 = device2 ? strdup(device2) : NULL;
 #endif

修改为：

#else
                 } else if (!strcmp(mount_point, "/sdcard") && has_fat) {
                     device_volumes[num_volumes].device = strdup("/dev/block/mmcblk1p1");
                     device_volumes[num_volumes].device2 = strdup("/dev/block/mmcblk1");
 #endif

3、重新编译整个工程new
