Can't mount ext4 partition

[jfc]

Hello,

I did connected a SATA SSD disc to an A20-OLinuXino-LIME but I'm not able to mount a Ext4 partition. I get the message:

EXT4-fs (sda2): couldn't mount RDWR because of unsupported optional features (400)

I don't have any issue with ext3 FS.
I'm using the Jessie image from Olimex. The root partition on the SD card is Ext4 and is OK. Is there any options needed to the mount command?

Try creating the ext4 partition on the A20 then you are sure about the right version and features

I did it already on the A20 using: mkfs.ext4 /dev/sda2
