Hi TI.

board : am62-sk-evm E3

lcd : dual lvds panel

img : tisdk-default-image-am62xx-evm.wic

my modify : panel-simple.c

static const struct drm_display_mode microtips_mf_101hiebcaf0_mode = {

.clock = 150275,

.hdisplay = 1920,

.hsync_start = 1920 + 32,

.hsync_end = 1920 + 32 + 52,

.htotal = 1920 + 32 + 52 + 24,

.vdisplay = 1080,

.vsync_start = 1080 + 14,

.vsync_end = 1080 + 14 + 8,

.vtotal = 1080 + 14 + 8 + 3,

};

The green color is strange as shown in the picture. Any solution?

Hello,

Are you sure the clock frequency and timing params are defined correctly? The frequency we defined came directly from the LCD manufracture so I am not sure if you can use the same values as us. Also, what about the "bus_format = MEDIA_BUS_FMT_RGB888_1X7X4_SPWG"?

Hi Krunal

.bus_flags = DRM_BUS_FLAG_DE_HIGH,

.bus_format = MEDIA_BUS_FMT_RGB888_1X7X4_SPWG,

.connector_type = DRM_MODE_CONNECTOR_LVDS,

( SPWG -> JEIDA ) was also tried, but with worse results.

thank you

Hello,

Have you confirmed the timing values with your LCD manufacture?
