Hi,
we are working with self-developed i.MX6 board. Now we have enabled U-Boot
splash screen support. It is working well, but we have problems with LVDS
interface.
If we configure LVDS we always get 56MHz LVDS clock although we configured
30MHz for LVDS clock via displays structure in the board file:
.bus = 0,
.addr = 0,
.pixfmt = IPU_PIX_FMT_RGB24,
.detect = NULL,
.enable = enable_lvds,
.mode = {
.name = "wvga-lvds",
.refresh = 57,
.xres = 800,
.yres = 480,
.pixclock = 33000,
.left_margin = 40,
.right_margin = 40,
.upper_margin = 3,
.lower_margin = 80,
.hsync_len = 10,
.vsync_len = 10,
.sync = FB_SYNC_EXT,
.vmode = FB_VMODE_NONINTERLACED
Changing the pixclock value doesn't affect the lvds clock output. We always get
56MHz.
Currently we are using u-boot version 2013.10.
Has anyone an idea what's going wrong?
Best regards,
Andreas
