Hi,
we are working at the moment with i.MX6DL. I tried to setup new display support
(RGB interface) in Bootloader U-Boot. There is a structure available, where I
can define all the display timings:
.mode = {
.name = "wvga-rgb",
.refresh = 57,
.xres = 800,
.yres = 480,
.pixclock = 33260,
.left_margin = 42,
.right_margin = 86,
.upper_margin = 10,
.lower_margin = 33,
.hsync_len = 128,
.vsync_len = 2,
.sync = 0,
.vmode = FB_VMODE_NONINTERLACED
But there I miss the edge definition of the pixel clock and data enable. I also
searched in the user manual about the i.MX6 IPU register where I can set the
active high or low information but I can't find it.
So can anybody tell me in which registers I can set the following information's:
V-Sync: Active high or low
H-Sync: Active high or low
Pixel Clock: Data is driven on falling or rising edge
Output enable: Active high or low
Data lines: inverted or not
If anybody can tell me how I can do this in U-Boot it would also help. H-Sync
and V-Sync activity I can control with the defines FB_SYNC_HOR_HIGH_ACT and
FB_SYNC_VERT_HIGH_ACT but the other controls (pixel clock rising or falling
edge, data enable active high or low, Data lines inverted or not) I'm missing.
Best regards,
