Current 2016.05 Uboot - which filesystems ? (1 reply)

Probably more a question for @bodhi than anyone, but any advise welcomed :)

My question is what file systems can the current 2016.05 Uboot boot ?

ext2 / ext3 - I know from my own experience work fine, although ext2 is a bit fragile with the lack of journal, so have preferred ext3

ext4 ? (says so on the post)

mdadm RAID 1 with 1.0 metadata / 0.9 metadata ... other RAID levels ? 1.2 metadata ?

f2fs ?

are my main contenders, and just for good measure :

btrfs ?

zfs ? (probably a no go on low memory ARM boards anyway)

EDIT: obviously I mean what fs can Uboot load kernel/device tree and initramfs from, sorry if that wasn't clear :)
