I have a 24bit LVDS display that I am running on PDK imx6dl AI board.
The images look like they are being displayed at the wrong color depth.
I have modified drivers/video/mxc/ldb.c to add a new entry for my
display:
static struct fb_videomode ldb_modedb[] = {
{
"LDB-XGA", 60, 1024, 768, 15385,
220, 40,
21, 7,
60, 10,
FB_SYNC_CLK_LAT_FALL,
FB_VMODE_NONINTERLACED,
FB_MODE_IS_DETAILED,},
}
I also modified my kernel board file to add a matching entry and made
sure to specify IPU_PIX_FMT_RGB24
static struct ipuv3_fb_platform_data qmx6_fb_data[] = {
{ /*fb0*/
.disp_dev = "ldb",
.interface_pix_fmt = IPU_PIX_FMT_RGB24,
.mode_str = "LDB-XGA",
.default_bpp = 24,
.int_clk = false,
},
{
.disp_dev = "ldb",
.interface_pix_fmt = IPU_PIX_FMT_RGB24,
.mode_str = "LDB-XGA",
.default_bpp = 24,
.int_clk = false,
},
{
.disp_dev = "lcd",
.interface_pix_fmt = IPU_PIX_FMT_RGB24,
.mode_str = "CLAA-WVGA",
.default_bpp = 24,
.int_clk = false,
},
}
Is there something else I need to setup in kernel in order to get a 24bit
LVDS panel working?
