Introduction iTOP6818 is 8-core embedded development platform, you can set the touch screen display system in ubuntu or HDMI display, but the official did not make a corresponding dual significantly different, namely a touch screen and HDMI display different picture. Based on individual needs, it completed the functional configuration, the configuration method will now be described below.
Configuration Roadmap recreate a node fb kernel to mount the HDMI device, the master device is a touch screen FB0, FB1 views of HDMI device, may be achieved by modifying the dual significantly different kernel driver code.
Configuration into the kernel code input command to enter the kernel make menuconfig graphical configuration interface, as follows: After the configuration, the following alternate route ./kernel/arch/arm/plat-s5p6818/drone device with the profile of device.c. c file, recompile the kernel to complete.
Significantly different dual implemented to achieve dual significantly different, i.e. fb0 and fb1 of operation can be realized by the framebuffer ubuntu system.
