Hello,Community

 

I am now working on Freescale  imx6dlsabreauto board with Yocto L3.10.17_1.0.2.

I connected a 7" 800 x 480 LCD display,and set the kernel command line

as below:

setenv mmcargs 'setenv bootargs console=${console},${baudrate} ${smp} root=${mmcroot} video=mxcfb0:dev=lcd,CLAA-WVGA,if=RGB565'

After the kernel started,the LCD display did not work(it displayed nothing).

 

But when I tested with LTIB L3.0.35,the LCD worked normally.

 

So could you tell me why LCD display doest not work under Yocto.

 

Best Regards,
