[DESCRIPTION]
emmc上使用LCA版本的时候，内置T或和外置T卡识别异常（normal mode and factory mode）
[SOLUTION]
1、修改alps\mediatek\config\project_name\ProjectConfig.mk中移除sd_ex 选项
RESOURCE_OVERLAY_SUPPORT = sd_ex LCA_ram LCA_ROM ==> RESOURCE_OVERLAY_SUPPORT = LCA_ram LCA_rom
2、alps\mediatek\config\project_name\ProjectConfig.mk中mtk_MULTI_STORAGE_SUPPORT = no 修改成yes
3、将alps\mediatek\config\project_name\vold.fstab原内容删除，填入如下内容
dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0
/devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1
/devices/platform/mtk-msdc.1/mmc_host
4、build new后再验证
