error when mount exfat disk #61

Closed wzhy90 closed 9 years ago

wzhy90 commented 9 years ago

In adb shell:

root@D6503:/ # insmod /system/lib/modules/exfat.ko
root@D6503:/ # mount -t exfat /dev/block/mmcblk1p1 /sdcard1                    
mount: Permission denied

Cannot mount the disk. When I use the Sony stock texfat modules it is OK. My device is Z2 D6502

This is SELinux problem

<7>[  473.224805] SELinux: initialized (dev mmcblk1p1, type exfat), not configured for labeling

How to fix this?
