[jagrati_chaudhary]

i am new to laysacpe ls1021a and NXP LLDP and i wants to build minimal root file system for ls1021s and trying to extract the kernel sources out of the SDK for ease of development.i already setup the environment and built a toolchain using "bitbake meta-toolchain" i wants to use this toolchain to build extracted kernel source for ls1021a out of sdk but i don't have any idea how to build  minimal root file system and extract the kernel sources?
