UBIFS boots only once!

Hello everyone,

I've managed to boot a "small" rootfs from my nand ( ~32 MB ), by using UBIFS ( UBI-FruStrations? ). Now when I create a larger rootfs ( ~64 MB ) it boots the first time, but afterwards no more.

I've tried almost everything but nothing seems to help me! I notice read errors the first time, but it continues to boot... I really don't know what I'm doing wrong here and I'm getting really frustrated too because of this weird behaviour!

-- Ubinize.cfg

     [RFS-volume]

     mode=ubi

     image=ubifs.img

     vol_id=0

     vol_size=192MiB

     vol_type=dynamic

     vol_name=rootfs

     vol_flags=autoresize

commands i've used to create UBI:

     mkfs.ubifs -r rootfs/ -o ubifs.img -m 2048 -e 126976 -c 1580 –F

     ubinize -o ubi.img -m 2048 -p 128KiB -O 2048 ubinize.cfg

I write my ubi image from within uboot:

     U-Boot# mw.b ${loadaddr} 0xFF {partition-size}

     U-Boot# tftp ${loadaddr} ubi.img

     U-boot# nand erase 0x00780000 {partition-size}

     U-boot# nand write ${loadaddr} 0x00780000 {filesize}

...and afterwards boot from nand...
