VGA DISPLAY

Other Parts Discussed in Thread: THS8135, DA8XX

Hi,

I am using Openboard-phyCORE-AM335x board and PCM-051 SOM for our project development.

We have designed a new PCB for THS8135 based on THS8135 EVM .

We interfaced with the TI-AM3359 ( Phytec phyCORE-AM335x).

We have added the support in Board file and timing parameters in Driver.

In Board file :

***********************************

}, {
.manu_name = "vga_vesa",
.controller_data = &lcd_cfg,
.type = "VGA_Monitor",
},

*************************************

In drivers/video/da8xx-fb.c

****************************************

[10] = {
.name = "VGA_Monitor",
.width = 640,
.height = 480,
.hfp = 16,
.hbp = 81,
.hsw = 63,
.vfp = 10,
.vbp = 33,
.vsw = 3,
.pxl_clk = 25000000,
.invert_pxl_clk = 0,
},

************************

While booting kernel the display parameters got detected and we are getting the resolution values(640x480@60HZ) on Monitor.

******************

[ 0.227722] da8xx_lcdc da8xx_lcdc.0: GLCD: Found VGA_Monitor panel
[ 0.245910] Console: switching to colour frame buffer device 80x30

******************

Now "VGA" is working fine.but once maximize the image or scroll the image right side corner of monitor,it suddenly change to black color.

For your Ref : LCD is Working good on same board.

Please Help me to resolve this.

For your quick reference attaching few screenshots with the above issues clearly visible.

Thanks in Advance
