Hello. I wish you all a happy new year!
In a similar fashion of the Linux Kernel, I am configuring my display. I managed to get it working with your help but there’s an issue. There are some artifacts that appear in the screen, that disappear later in the kernel. Those kind of artifacts used to appear when I didnt configure the clock on the kernel.
Did anyone successfully invert the pixclk polarity? I tried the following in my apalis_imx6.c display definition
- Include the mxcfb.h in apalis_imx6.c to change .sync to FB_SYNC_CLK_LAT_FALL since videomode.h does NOT have this definition (no change)
- Change to .sync to every property in videomode.h (some of these actually break my image)
define FB_SYNC_HOR_HIGH_ACT 1
define FB_SYNC_VERT_HIGH_ACT 2
define FB_SYNC_EXT 4
define FB_SYNC_COMP_HIGH_ACT 8
define FB_SYNC_BROADCAST 16
What’s the correct way to invert the polarity in U-Boot?
