Support exFAT filing system on SD card.

[divyeshmarne0]

Hi Team,

1. We have imx8mm device with Android 11 code. Added support for SD card in fstab entry.
2. Could you please help here to support the exFat filing system on SD cards.

also we need following path to locate external storage (SDCARD) in adb shell:

1. /sdcard/

Currently it is points to the internal memory which is android file system.

We need /sdcard path as a /sdcard/<Sdcard_name_byUser>

Thanks

Hi @joanxie ,

We have added support for exfat in Android 11 code base. Now exfat formatted SDcard is supporting.

But we are not able to create folder in /sdcard folder. We need External sdcard points to the /sdcard/ClubCar directory. But in current implementation it is pointing to internal storage of device. need to change path to point External sdcard. Could you please help here ?

Thanks

Hi @joanxie ,

I tried to format SDcard with exfat and it is working through adb shell :

evk_8mm:/ # mkfs.exfat /dev/block/mmcblk1p1
mkexfatfs 1.3.0
Creating... done.
Flushing... done.
File system created successfully.

After executing these commands, I can see type=exfat.

BUT I need default format exfat without any commands through adb shell...
