Creating a new .imx.gz file

Hello all,

When I installed ubuntu in my beaglebone black I got the ubuntu-saucy-13.10-armhf-3.8.13-bone30.img.xz and wrote in board with xz -cd ubuntu-saucy-13.10-armhf-3.8.13-bone30.img.xz > /dev/mmcblk1 command. Now, I did some modifications in the system and wanna create a new .img.xz file with my flash content. How Can I create that file?


Hi, Can anyone help me?
