[yocto] First UBI build

[DAMARLA Satya Swaroop]

Hi Guys,

I had great success and actually feel yocto with building images. Now I
want to run the image from the flash drive and trying to build a UBIFS but
I get strange errors which I didnot get when I am building a normal tar.gz
file for the SDCARD. The error is as follows... Can you guys please tell me
what is the new stuff I had to add to overcome this issue?

*| Size after prelinking 276884.*
*| Error: min. I/O unit was not specified (use -h for help)*
*| ERROR: Function failed: do_rootfs (log file is located at
