i.MX6 SOLO HDMI Support

[mohammedazlum]

Hi Team,

According to the datasheet MCIMX6S1AVM08AD part doesn't support VPU and GPU. However when we go through the datasheet it can support HDMI, LVDS, RGB, LVDS display from IPU.

May I know how the same CPU (MCIMX6S1AVM08AD ) can support these display when there is no VPU ? There should be some image format to display the content on display. So when there is no VPU how the encoding and decoding is occurs on the display ?

Regards,

>>What will be the default display format at display modules when there is no VPU ?

--VPU has no relations to display, it means VPU doesn't affect display funtion.

--The output of the display interface: LVDS(0/1)/RGB24/HDMI/MIPI DSI

You can control which interface is used to output display data in the u-boot environment variable.

In linux BSP, the default is LVDS1.

Hi mohammedazlum ,

See below,please!

>>May I know how the same CPU (MCIMX6S1AVM08AD ) can support these display when there is no VPU ? 

The display is only related to IPU. The VPU is a module used to support H.264/MPEG4 encoding and decoding, and has nothing to do with display.

>>So when there is no VPU how the encoding and decoding is occurs on the display ?

You can only decode and encode video data through software. However, the performance will be far from ideal.

Therefore, if you need H.264/MPEG4 encoding and decoding functions, 2D and 3D acceleration functions, it is best to choose a processor part number with VPU and GPU.

Hope  this information is helpful to you.

Have a nice day!

Dear Weidong,

Thanks for the reply.
