 +If you want to extract the config file from existing linux image, zImage or bzImage, do the following (only applies if was built with the IKCONFIG option):
  
 +Download the files with the linux sources:
 +
 +<​code>​
 +cd 
 +
 +mkdir krn
 +
 +cd krn/
 +
 +wget ftp://​ftp.embeddedarm.com/​ts-arm-sbc/​ts-7260-linux/​sources/​tskernel-2.6.21-ts-src.tar.gz
 +</​code>​
 +
 +Unpack the linux kernel sources:
 +
 +<​code>​
 +tar xvfz tskernel-2.6.21-ts-src.tar.gz
 +</​code>​
 +
 +Go into the directory of the kernel sources:
 +
 +<​code>​
 +cd linux-2.6.21-ts/​
 +</​code>​
 +
 +Type: 
 +
 +<​code>​
 +chmod 755 ./​scripts/​extract-ikconfig
 +</​code>​
 +
 +Run: 
 +
 +<​code>​
 +./​scripts/​extract-ikconfig /tmp/zImage > /tmp/config
