Can I use dual display on STM32MP157C chipset?

[Machilus]

Hi all

​

​I want to implement dual display using STM32MP157C chip and OpenSTLinux system.

Is it possible to implement dual display using MIPI DSI / LTDC / HDMI-CEC?

If you know the answer above, please reply.

​

Hi @Machilus​ ,

current implementation allows only one display to be use.

Following connections are available:

• RGB parallel display get their pixels from LTDC
• DSI get their pixels form LTDC (internally)
• HDMI (external) bridge get their pixels from LTDC 

Best regards,

Milan

Hi @mleo (ST Employee)

Thanks for the reply.

I have one more question.

Is it possible to build an "xwindows" based GUI environment on "OpenSTLinux" using the STM32MP151C chip?

I'll wait for your reply.

Bast regards
