Hi, so I have tried myself compile an fuse based exfat support (relan/github) to my Jolla Tablet. Exfat binary make installs with no hiccups and I can format 64gb microsdxc as exfat. The only problem I'm facing is that mount-sd script will not mount the card /media/sdcard/(identifier). So then I thought formatting the microsd as btrfs. But guess what, "[root@Jolla nemo]# bash: mkfs.btrfs: command not found". What the???

Is fat32 formatter my only option for now?

Tried mkfs -t btrfs? Tried any other fs than btrfs? Tried formating the card to exFAT on Windows (or any other SDXC-compatible device) and see if it mounts then?

ext4 is used instead of btrfs in tablet. I've tested to compile exfat fuse inside the tablet, and it managed to mount exfat cards by hand just fine (havent tested the script as it might need some tuning).

I don't know how you did manage compile the exfat to /usr/sbin/ and get it mount, but my few manual mount efforts always resulted to an error message: [root@Jolla sdcard]# mount -t exfat /dev/mmcblk1p1 /media/sdcard/
mount: unknown filesystem type 'exfat'

I prefer using ext4 on my systems.

Of course... and with no journaling enabled. Hadn't thought about that. Thanks :) I have now formatted my microSDXC card as ext4 without journaling. It works.

ext4 without journaling is a great other option besides btrfs! I can confirm a microSDXC 128 GB card formated to ext4 works well in Jolla Tablet :-)

About Android apps linked to the sd card I got stuck ... Trying to change permission for sd card like: /opt/alien/etc/... but where?
