Use IMX8M and DVI to drive ITU-BT656

Hello,

Is it possible to know when DVI driving ITU-BT656 will be available for IMX8M BSP ?

As far as i know it's not yet developped :

mxsfb.c\fbdev\video\drivers - linux-imx - i.MX Linux kernel 

My goal is to display using CCIR656. Maybe there is an other possibility ?

(I try using hardware like ad7610 but it doesn't work)

Thanks in advance for your answers.

Best regards

Fred

Hi Fred

nxp provides drivers only for lcd boards provided with i.MX8M reference board, for example

described on below link

Hi Igor,

 

I don't want to use flat panel ! 

My only way to use IMX8M now is using CCIR656 output. 

 

As DVI is explained in datasheet, i believed that is was developped. But reading sourcecode, i see that its wasn't. 

Have you got a roadmap for that ??? (IMX6 support CCIR656 in the past).

Hi Fred

not all features which are described in datasheet are supported

in software. Supported features in software can be found in linux documentation on

nxp official software page link
