[yocto] First UBI build

[Luo Zhenhua-B19537]

Add below two variables in conf/local.conf, the value is just for sample and might need change.

MKUBIFS_ARGS = " -m 512 -e 15360 -c 3600 "
UBINIZE_ARGS = " -p 16KiB -m 512 -s 512 "


Best Regards,

Zhenhua

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.
