hello,Dear community, I want to display the logo through LVDS when uboot starts. The uboot version I used is 2015-04, and my chip is IMX6D. I have not made any changes to uboot, I can specify through the debug information, uboot executed enable_lvds(), and also executed video_init, video_logo and other functions, but my screen did not respond at all, then when I went to measure, I Found that lvds has no signal. Because in the kernel phase, my screen is displayed properly, so I think my hardware is no problem. Maybe it's a problem with my uboot configuration. Can you help me see where I need to change?
