touchscreen, LVDS0, Relationship?

[stuartmorton]

HI All,

We are converting from Win CE 7 to Android Lollipop 5.1 (freescale disto)

The board was based on the sabresd duel light development board

I have built the imx6 distribution as described in the document android_users_guide.pdf and can down load it to the board and it runs and I get a debug output on ttymxc0.

I have removed the drivers for the touch screen and added our new driver that is falling to work.

There is also no output on the LVDS0 screen.

From reading you users comments on this site, this is because the touch screen driver is not loaded

So I can understand more about what is going on, what is the relationship between the touch screen driver and the LVDS0 channel.

Hi Stuart

there should not be strict relationship between the touch screen driver and the LVDS0.

One can first customize lcd to get correct image like in example below, then touch screen.

hi Igor,

thanks for the quick response,

I have managed to set up the LVDS0 to the correct settings and the android splash screen is displayed fine,just before the end of the android splash video the screen dims considerably,

when the desktop is available I change the brightness but this doesn't recover the screen level?

Hi Stuart

what touchscreen is used, for example one can look at

integration of ft5x06 in Android 5.0
