1、The Framebuffer Console 详细的介绍了相关操作系统编译选项，不仅包括了graphics，还介绍了相关的 Characters和鼠标键盘等设置。

2、OSL TFT Driver 是xilinx的文档，介绍了与上述相类似的内容。
Kernel Configuration
The following items are required in the kernel configuration to use the driver.

Select the Xilinx Frame Buffer (CONFIG_XILINX_FB_XILINX) in the kernel configuration by following this path thru the menuconfig.

From drivers->
Graphics support->
Support for frame buffer devices->
Xilinx frame buffer support

Select the Frame Buffer Console driver (CONFIG_FRAMEBUFFER_CONSOLE) in the kernel configuration by following this path thru the menuconfig.

From drivers->
Graphics support->
Console display driver support->
Framebuffer Console support

Note: “Console display driver support” does not show up in the menuconfig until you select Virtual terminal (CONFIG_VT) in the kernel configuration by following this path thru the menuconfig.

From Device Drivers->
Character devices->
Virtual terminal

Kernel Command Line
Add “console=tty0” to use the frame buffer as the primary console.

3、修改 petalinux-config 中的bootargs 变量，将其中 的 console=ttyPS0改为 tty0 ，操作系统启动后，相关信息就显示在 Framebuffer 设备上了。（U_boot的bootargs参数详解）

4、测试表明，只要在uboot中设置 bootargs=console=tty0。就可以使得系统的输出信息输出到tty0上，也就会到所有的ttyn上。如果设置 console=tty1，则相关信息只会输出到tty1上，其他的ttyn和ttyPSn都收不到这些信息。
