Dear Community,
board: imx6q;
version: u-boot-2009.08;
i did what this doc said: https://community.nxp.com/docs/DOC-98109
but the logo color is not normal, it si green like this:
what is wrong? and this is my head file:
//#define IPU_OUTPUT_MODE_HDMI
#define IPU_OUTPUT_MODE_LVDS
// #define IPU_OUTPUT_MODE_LCD
#ifdef IPU_OUTPUT_MODE_LVDS
// For LVDS, 1920*1080 resolution, dual channel
#define DISPLAY_WIDTH 1920
#define DISPLAY_HEIGHT 1080
#define DISPLAY_BPP 32
#define DISPLAY_IF_BPP 24 // RGB24 interface
#define DISPLAY_HSYNC_START 80
#define DISPLAY_HSYNC_END 68
#define DISPLAY_HSYNC_WIDTH 12
#define DISPLAY_VSYNC_START 15
#define DISPLAY_VSYNC_END 15
#define DISPLAY_VSYNC_WIDTH 8
#define DISPLAY_PIX_CLOCK 139526400 //(DISPLAY_HSYNC_START + DISPLAY_HSYNC_END + DISPLAY_HSYNC_WIDTH + DISPLAY_WIDTH) *

#define LVDS_SPLIT_MODE // For dual channel split mode.
#define DISPLAY_VSYNC_POLARITY 1
#define DISPLAY_HSYNC_POLARITY 1
#define DISPLAY_CLOCK_POLARITY 1
#define DISPLAY_DATA_POLARITY 0
#define DISPLAY_DATA_ENABLE_POLARITY 1
#define IPU_NUM 1 // 1 for IPU1, 2 for IPU2.
#define DI_NUM 0 // 0 for DI0, 1 for DI1.
#define LVDS_PORT 0 // 0 for LVDS0, 1 for LVDS1.
#define DI_CLOCK_EXTERNAL_MODE //When clock external mode was defined, the DI clock root will be PLL3 PFD1,
//without this macro, the DI root clock is IPU internal clock.
nothing changed, just above, can you help me? what should i do? what is info do you need? tell me.
wating for your reply?
thank you.

Hi,
kernel:
drivers/video/mxc/ldb.c
static struct fb_videomode ldb_modedb[] = {
...
{
"LDB-1080P60", 60, 1920, 1080, 12048,
80, 68,
15, 15,
12, 8,

FB_MODE_IS_DETAILED,},

0, 31,

FB_MODE_IS_DETAILED,},
arch/arm/mach-mx6/board-mx6q_sabresd.c:
static struct fsl_mxc_ldb_platform_data ldb_data = {
.ipu_id = 0,//1
.disp_id = 1,
.ext_ref = 1,
.mode = LDB_SEP1,
.sec_ipu_id = 0,//1
.sec_disp_id = 0,
};
i use this L3.0.35_4.1.0_uboot_logo_keep_patch_2013-11-22.zip,
[fulinux@ubuntu uboot-imx]$ git branch
* imx_v2009.08_3.0.35_4.1.0
[fulinux@ubuntu uboot-imx]$ git log
6bd825c ENGR00327364 iMX6x: Ensure that the bandgap self-bias circuit is disabled after boot. (Ranjani Vaidyanathan, 1 year, 7 month
5caea2f ENGR00329930-2 MMC: Fix debounce problem in the tuning algorithm (Ye.Li, 1 year, 8 months ago)
...
i have modified nothing before patch, but i add backlight power gpio code:
static void setup_lvds_iomux(void)
{
....
#if 1
gpio_direction_output(IMX_GPIO_NR(1, 2), 1);
udelay(10*1000);
gpio_set_value(IMX_GPIO_NR(1, 2), 0);
udelay(10*1000);
gpio_set_value(IMX_GPIO_NR(1, 2), 1);
gpio_direction_output(IMX_GPIO_NR(4, 5), 1);
udelay(10*1000);
gpio_set_value(IMX_GPIO_NR(4, 5), 0);
gpio_direction_output(IMX_GPIO_NR(1, 7), 1);
udelay(10*1000);
gpio_set_value(IMX_GPIO_NR(1, 7), 1);
#endif
}
anything info which you need, tell me. this problem makes me very anxious.
and when i change " #define DISPLAY_BPP 32" to 24, and change "logo_1024x768_24bpp.bmp" to "logo_1920x1080_24bpp.bmp", and then screen like this:
but i am sure my lcd panel support 32bpp, because uboot bootargs is :
"video=mxcfb0:dev=ldb,1920x1080M@60,if=RGB24,bpp=32 consoleblank=0 ldb=spl0 ldo_active=on fbmem=128M" and kernel displays ok!
this is panel schematic:
Waiting for you reply!
thankyou,
fulinux.
