I use the Easybox 904xDSL with snapshot from 14.12.2018
Here looks like the same problem
It does not work when i format the stick on my PC and it does not work when i format the stick on the router
I know it was working a month before.

Does f2fs working by everyone on a new snapshoot ?

and the discussion regarding big endian:

Still not fix, same old issue. Im tested on erlite.

OpenWrt SNAPSHOT, r8846-99ddff0
root@OpenWrt:/# opkg list |grep f2fs*
libf2fs - 1.12.0-1
mkf2fs - 1.12.0-1

The Error is only on my Easybox 904x (mips) not on my Raspberry Pi 3 (arm)
Im shure it is an general Kernel Problem on ca~ newer them 4.14.82, because, i try differend f2fs-tools on different maschines: no working, same error
I build a very raw f2fs patch with diff from the old 4.14.82 kernel to the newer 4.14.89 and put them to:
target/linux/lantiq/patches-4.14
and it works but with this message:

[  147.088665] F2FS-fs (sda1): Found nat_bits in checkpoint
[  151.578307] F2FS-fs (sda1): Mounted with checkpoint version = 6551e073

but it works

here are the patch: 4099-fix-f2fs-on-mips.patch
please put them to:
target/linux/lantiq/patches-4.14
or other target mips patch-4.14 directory

@ rrcsaba which device ?
It will be interessting too if f2fs work/not work (without patch) on other mips/no mips devices

It works on little endian devices.

Despite __le being everywhere in the code, basically no testing is being done on big endian devices.

There's a patch to fix this error in the mailing list. Should be available in time for the next release.

Thanks @Plonk34
Your patch working with octeon soc.

I've uploaded a upstream fix that made the MyBook Live (PowerPC SoC) work again:
