Hi all,

   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.

   4. modify the u-boot environment variables as below:

     a.) setenv fdt_file imx6slevk.dtb

     b.) setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=${mmcroot} epdc             video=mxcepdcfb:ES103TC1,bpp=16'.

   5. boot into Linux kernel, run unit-test: "/unit_tests/Display/mxc_epdc_fb_test.out", should be able to have test patterns    running   on EPD.

   But we have a problem,Unable to open /dev/fb2.

   Could somebody help me?
