here we use pre-build L4.1.15_1.1.0-ga Linux 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 your SD card(>800 MBytes) with command(I'm running this in Ubuntu): "dd if=fsl-image-gui-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=${mmcroot} epdc video=mxcepdcfb:E060XH2C1,bpp=16'
          (originally this is "mmcargs=setenv bootargs console=${console},${baudrate} root=${mmcroot}")

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