[U-Boot] Problems with creating an UBIFS partition with uboot

[Karl Krach <mailinglists@blueSpirit.la>]

Hello all,

I ve googled a lot and read many mailing list entries, but got stuck now with the following problem:

=>  ubifsmount rootfs
UBIFS error (pid 0): ubifs_read_node: bad node type (0 but expected 6)
UBIFS error (pid 0): ubifs_read_node: bad node at LEB 0:0
Error reading superblock on volume 'ubi:rootfs'!

1) I ve erased my nand-partition with 'nand erase'
2) I ve created a UBI partition with 'ubi part'
3) I ve uploaded my UBI image with 'tftp'
4) I ve created an volume with 'ubi create'
5) I ve written the image to the volume with 'ubi write'
6) I wanted to mount the volume
     -->  and failed

INFO: I was able to mount a UBI image, which I ve created on the device, when booting from NFS. So I guess that the UBI image is OK.

Was did I wrong?

Thanks a lot,
Charly





Here is the complete history:

I ve created an UBI image from an UBIFS file with the following cmd:

     ubinize -orootfs.ubi.img -m2048 -O512 -p128KiB ubinize.cfg

and this ubinize.cfg

     mode=ubi
     image=rootfs.ubifs

     vol_size=512MiB
