I have a buildroot system, which mounts ubi ok in linux, but in u-boot I get error 22
When starting in linux this is in dmesg:

but when it try to attach:
=> ubi part rootfs
ubi0: attaching mtd1
UBI init error 22
It's on an embedded system which uses older versions U-Boot 2016.11 and Linux/arm 4.4.289 Kernel
I suppose some parameter is wrong somewhere, can somebody give me some advise where to look?
