[U-Boot] ubifsmount fails after booting linux

Hello,
the idea is, to give the user a possibility to update its system without tftp
or a second partition. First, the user saves the update file (rootfs.ubifs) to
its rootfs, and on the next reboot the uboot loads the update file to the RAM
and flashes the update file.
Problem: After booting linux once, I cannot mount my ubifs from uboot any
more. (But: On linux it is still working fine...)
I receive once again:
UBIFS error (pid 0): ubifs_read_node: bad node type
(255 but expected 6)
UBIFS error (pid 0): ubifs_read_node: bad node at LEB 0:0
Error reading superblock on volume 'ubi:rootfs'!
Best regards,
Charly
