how to imx8mq-evk MIPI-Display + HDMI dual display

[kangmw086]

hi.

i used i.mx8mq-evk and android8.1.

1. Can IMX8 use MIPI-Display and HDMI at the same time?

2. If possible, how should I modify it in kernel?

3. Is it possible to switch from Android APP to HDMI output while printing the screen with MIPI?

regards!

Thank you for your reply.

Can't I use IMX8 HDMI directly?

Should it be used in MIPI + MIPI-DSI-to-HDMI format only?

I want to use IMX8 HDMI port right away.

I want to use IMX8 HDMI + MIPI-DSI...

regards.

Hi

Of course you can use single display.Please see the quick user guide.Our bsp support single hdmi,single mipi,dual hdmi&mipi and dual hdmi.The MIPI-DSI TO HDMI just convert DSI data, you can use hdmi+mipi.Its  same setting.

Like Quick start guide, u-boot gave the command, but it didn't work.

So I am modifying the kernel.

Should HDMI be operated in DCSS?
And can MIPI-Display be operated from lcdif?

I'm used I.MX8 and Android 8.1.

thanks.

Then can I print it out with MIPI and switch from Android Application to HDMI?

I want to implement MIPI and HDMI transitions into software.

And can I change the resolution using software?

Android confirmed resolution changes with the wm size 1280x700 command.

thank you.
