seems ubifs cannot find any space available
I tried old openwrt , mounted /dev/mtdblock5 and got about 70% free
space but only afer nand format from routerboot. Rest is maked bad and
could be bad indeed..
but problem remains.. altho I have enough to flash kernel, ubi does
not see that free space.
Any help from anyone is much appritiated.
