Hello, to make long story short, I am trying to use a specific HDMI display, but when I connected it with Imx6dl sabre auto it doesn't interact.

And, what I found is that I need to change mxc.hdmi.c (kernel/drivers/video/fbdev/mxc) into right sync rate like below.


static const struct fb_videomode vga_mode = { / 640x480 @ 60 Hz, 31.5 kHz hsync / NULL, 60, 640, 480, 39721, 48, 16, 33, 10, 96, 2, 0, FB_VMODE_NONINTERLACED | FB_VMODE_ASPECT_4_3, FB_MODE_IS_VESA, };


But, after modifying this, I think I need to update dts and uImage /boot, but don't know the detail steps.


So, I was wondering if anyone could tell me what I have to do to move forward?
