To add a few more details (I'm the software dev on the team):
The current set up we are testing with is a beagle bone black connected to
a 7" 1024x600 LCD. The LCD is part of a dev kit from chipsee.com.
The driver for the LCD is:
drivers/video/da8xx-fb.c
Inside the driver, the following settings are used
/* INNOLUX HJ070NA13A*/
[8] = {
.name = "HJ070NA13A",
.width = 1024,
.height = 600,
.hfp = 1,
.hbp = 45,
.hsw = 30,
.vfp = 12,
.vbp = 22,
.vsw = 2,
.pxl_clk = 25000000,
.invert_pxl_clk = 0,
},
We have tested another 7" 1024x600 display, model YXD070NA13-3.4 which does
work correctly.
The other screens we have tried:
10.1", 1024x600, YX101IF40-A, almost works but image is corrupted
10.1", 1280x800, YX101TN1280800-40, screen is completely blank
We would be grateful if anyone could answer / provide information for:
1. Is the da8xx-fb.c driver suitable for the 10.1" displays?
2. Are there any other changes we need to make to the kernel to make the
10.1" displays work?
3. What is the maximum screen resolution for BeagleBoneBlack running
android?
4. What are the correct settings (eg Horizontal Front Porch) for the
10.1" displays?
5. How do you determine the display settings, as the LCD datasheets only
provide a very basic timing diagram?
6. All the displays we tried use a 40pin LVDS connection, are there any
electronic/connection issues we need to be aware of?
