How to get proper Green color in RGB combination on LCD

Question asked by Jai Prakash on Sep 4, 2014

Hello  ,

 

                I have wanboard quad with it i have interfaced my ortus tech 3.5" LCD. I have  my application running fine on LOGIC PD processor and getting correct RGB colour combination. And now i am using same application on imx6 processor with kernel version 3.0.35, getting RED and BLUE color perfect but problem is in GREEN colour and currently i am using 16 bit value of RGB565 combination to write on LCD buffer using Frame buffer node /dev/fb0. My boot argument is given below --

 

setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} video=mxcfb0:dev=lcd,OT27,if=RGB565 video=mxcfb1:off

 

Also using fbset command i have set the depth of pixel to 16

 

root@wandboard-quad:/usr/bin# fbset

 

mode "240x320-64"

        # D: 8.000 MHz, H: 21.053 kHz, V: 63.990 Hz

        geometry 240 320 240 320 16

        timings 125000 10 120 3 3 10 3

        accel false

        rgba 5/11,6/5,5/0,0/0

endmode

 

so where i have to look for problem i.e in application or driver level.

 

 

Thanks and Regards
