[ADV7611]Enabling video adjustmnets

Question asked by ravi1 on Mar 31, 2015

  I am trying to change hue, so as per ADV7611 software manual we have to enable video adjustments(VID_ADJ_EN).

  The VID_ADJ_EN value is 0, so I tried setting the VID_ADJ_EN using i2cset, but it is not changing.  The i2cset command is not giving any error.

       #i2cget -f -y 1 0x4d 0x3e                                                                                 

       0x00

       #i2cset -f -y 1 0x4d 0x3e 0x80                                                                            

       #i2cget -f -y 1 0x4d 0x3e

       0x00

       #

 

  Can you please help me why I can't able to set VID_ADJ_EN. Following is the i2c dump.
