Here we use pre-build L4.9.88_2.0.0_images_MX6SLEVK.tar.gz as our boot-image, steps to setup/boot/test EPDC:
1.Download and decompress BSP pre-build image package .
2.Program the SD image on the SD card(8GB) with command(I'm running this in Ubuntu): "dd if=fsl-image-qt5- validation-imx-xwayland-imx6slevk.sdcard of=/dev/sdb;sync"
3. Insert SD card on i.MX6slevk board, connect debug-UART and power-on the board.
