+ | As we tested cvbs mode with our monitors, overscan setting is needed. | ||
+ | |||
+ | For example, in case of 480cvbs mode, the following values can be used. | ||
+ | <code> | ||
+ | # echo 20 20 695 478 > /sys/class/graphics/fb0/window_axis | ||
+ | # echo 0x10001 > /sys/class/graphics/fb0/free_scale | ||
+ | </code> | ||

+ | * Ubuntu : Available with 3.14.79-89 (Oct 13, 2016) or higher version | ||
+ | </WRAP> | ||
+ | |||
+ | There are two modes of CVBS, **480cvbs** and **576cvbs** on C2. | ||
+ | |||
+ | You need to modify boot.ini to set CVBS output. | ||
+ | <code> | ||
+ | setenv m "480cvbs" | ||
+ | setenv cvbsmode "480cvbs" | ||
+ | |||
+ | setenv bootargs ${bootargs} cvbsmode=${cvbsmode} | ||
+ | </code> | ||
+ | |||
+ | And make sure the **vout** mode is set as **hdmi** mode. | ||
+ | <code> | ||
+ | setenv vout "hdmi" | ||
+ | </code> | ||
