imx6 disabled screen as console

[864535720]

Hello everyone
  My development board is IMX6Q-sabresd, and the version of my linux operating system is: 3.14.52.
Now I want to use my debug serial port as a normal serial port to transfer data. I changed console = ttymxc0 to console = error under uboot. With this modification, the debug serial port can be used as a normal serial port to communicate. But at startup, the init process will print some information to my lvds screen. This makes customers look uncomfortable.
Later I modified the configuration options of the kernel:
Configuration before modification:
CONFIG_FRAMEBUFFER_CONSOLE = y
CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY = y
CONFIG_FRAMEBUFFER_CONSOLE_ROTATION = y

Modified configuration:
# CONFIG_FRAMEBUFFER_CONSOLE is not set

After the modification, the init process does not print information to my lvds screen, but my logo is not displayed on the screen when I boot up.

Is there any good solution to my current problem?
