Hi iamdharm20@gmail.com,

Are you flashing pre-built SD card image?If yes, then please go through below mentioned approach.

The sdcard image that comes in the archive for newer releases only works on i.MX6Q-SDB board. To build an image for i.MX6Q-sabre-auto, you need to follow the steps from the i.MX Linux User Guide, chapter 4.3 (Preparing an SD/MMC card to boot), which comes with Linux Documentaion.

Since the kernel image and the root filesystem are same for all various i.MX boards specified in archive you downloaded, you can just flash the already available sdcard image.

Once you flash the already available sdcard image, you need to follow below steps for your board:

1) Flash the U-boot image for your board to the SD card. In your case "u-boot-imx6qsabreauto_sd.imx" will be used.(Steps to flash only U-boot will be available in i.MX Linux User Guide)

2) Make sure the dtb for your board(zImage-imx6q-sabreauto.dtb) is available in the first partition.If not, please copy the dtb from prebuilt images to the first partition of SD card. Also, make sure that U-boot variable "fdt_file" points to the the dtb file you are using.
