interfacing SSD1963 LCD with imx6ul

Hi Team,

we are using a LCD display with SSD1963 as LCD controller and TSC2046 as a touch controller. We are trying to interface this LCD with imx6ul board. kindly let us know,how we can proceed further on this interface testing.

we have found the linux driver for the LCD controller used.

https://github.com/sirinsoftware/lcd-drivers/blob/master/ssd1963.c

But, how can we connect the LCD display with the board and configure the drivers to test it with a sample Qt example.

Regards,

Hi joanxie,

Thanks for the reply and sorry for the late response. I have gone through the links referred by you.

We are using the LCD from united Display and the datasheet is attached for your Reference. The LCD works on Single Port LVDS Signals. But the Imx6ul EVK Board Supports Parallel Interface for LCD.

we can't test the united display LCD with imx6ul EVK Board.

My Questions are:

1. Do imx6ul Processor supports LVDS interface to connect the LCD. if yes, what needs to be modified in the device tree file.

2. Is the parallel interface signals have PinMUX So that we can change the those signals to LVDS in the device tree or the Pins are dedicated only to parallel Interface.

3. How can we test the attached display on imx6ul EVK Board.

i.mx6ul couldn't support lvds directly, maybe you need to add converter if you need to connect lvds lcd display
