This may be a old and simple question, but I wasn't able to find a proper answer although I was surfing the net for days.
Im new to Sabre Lite. I installed LTIB and checked-out the i.MX6 kernel 4.1.0 source and compiled it as pointed out in the following post.
http://boundarydevices.com/cross-compile-i-mx6-kernel-using-ltib-toolchain/
I believe that it went smooth and I got the uImage created under following path
~/linux-imx6/arch/arm/boot/uImage.

following is the last few lines of console output of the compilation

......

Download Linux documentation package from Freescale web site from here: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&nodeId=018rH3ZrDRB24A&fpsp=1&tab=Documentation_Tab

In Linux User's Guide there's instructions on how to create SD card that can be booted from. However, Freescale documents refer to SABRE SDB boards, SABRE Lite is different as i.MX 6 boots from SPI flash at first, I believe. Basically for SABRE Lite you can just have fat32 partition on SD card containing uImage and a ext3 partition with the file system you'd like to use. Then modify u-boot script accordingly.

For ease of use, you might look at Yocto: Freescale/fsl-community-bsp-platform · GitHub

Supported boards are listed here: Freescale/fsl-community-bsp-base · GitHub

There's instructions here on i.MX Community as well how to get started with Yocto.
