How set mx6q_sabresd output the display data to YUV format

Question asked by kai sun on May 15, 2013

HI:

     I have modefiy code.


1 . on the Kernel mxc_lcdif.c data structure inside lcdif_modedb of adding the Video Mode

{

               /* 1920x1080 @ 60 Hz , pixel clk @ 148.5MHz */

               "LCD-1080P", 60, 1920, 1080, 6734, 148, 88, 36, 4, 44, 5,

               FB_SYNC_DATA_INVERT,

               FB_VMODE_NONINTERLACED,

               0,},

                2 .  delete  #define BT656_IF_DI_MSB 23

                 3 . setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw ip=none video=mxcfb0:dev=lcd,LCD-1080P,if=YUYV16,fbpix=RGB565'




        i hope have a YUV4:2:2  output on the Parallel port.

 

     but i  measured by the oscilloscope:

                                     pclk = 27Mhz,vsync=57.6Hz, hsync=29.3Khz.
