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[] =
{
