Hi all!

 

I'm new in armbian, and I'm just starting to fun:)

 

I want add new video mode to kernel:

  800x600 (0x45) 36.000MHz +HSync +VSync
        h: width   800 start  824 end  896 total 1024 skew    0 clock  35.16KHz
        v: height  600 start  601 end  603 total  625           clock  56.25Hz

 

I have read about this on the forum but I do not know how to calculate table ptbl[] in:

drivers/video/sunxi/disp2/hdmi/aw/hdmi_bsp_sun8iw7.c

 

static struct para_tab ptbl[] =
{
	{{6			, 1	, 1,  1,		5,	 3, 	0,		1,	 4,		0,		0,	160,	20, 		38, 	124,	240,	22,		0,		0	}},
	{{21		, 11, 1,  1,		5,	 3, 	1,		1,	 2,		0,		0,	160,	32, 		24, 	126,	32,		24,		0,		0	}},
	{{2			, 11, 0,  0,		2,	 6, 	1,		0,	 9,		0,		0,	208,	138,		16, 	62, 	224,	45,		0,		0	}},

};

 

and

video_timing[] in

drivers/video/sunxi/disp2/hdmi/aw/hdmi_core.c

 

how calculate pll_video in script.bin?

 

Can you help me?

 

Best Regards

 

ps.

for video_timing[] I find calculator:

http://www.epanorama.net/faq/vga2rgb/calc_v15.html

 

remains calculate for table ptbl[]  (drivers/video/sunxi/disp2/hdmi/aw/hdmi_bsp_sun8iw7.c)

Check this out for calculation, looks easier I think https://forum.armbian.com/topic/6596-howto-setting-up-resolution-1600x900/?tab=comments#comment-50482 but it works only at runtime. With reboot it gets lost.
