Hi all,
I see cmd_logo_814x.c for showing logo and colorbar in u-boot, so I modify it for my lcd panel with DM385 IPNC.
I referenced http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/211072.aspx?pi239031349=1 and use the configuration for 576i. It works.
My panel is setted to YUV 720 PAL mode , and can display colorbar now.
But I got stuck while showing logo. I saw two functions "ti810x_dispmgr_create_grpx_conf_descriptor" and "ti810x_dispmgr_setup_layers_DVO2" have some settings about dvo2. My question is how do I adjust it to fit my settings in VENC(576i) so that I can see correct logo in panel. Thanks.
Here is my setting now:
#define LCD_WIDTH 720
#define LCD_HEIGHT 288
#define WIDTH 720
#define HEIGHT 576
#define LCD_STRIDE LCD_WIDTH*3
#define LCD_FRAME_SIZE (LCD_STRIDE * 576)
size = ti810x_dispmgr_create_grpx_conf_descriptor(1, list_addr + 0x20000, payload_buffer + 0x10,720,576);
size = ti810x_dispmgr_setup_layers_DVO2(list_addr + 0x20000,LCD_STRIDE,720,576,disp_time,disp_fps,lcd_paddr);
The following bmp logo is (720*288)
The LCD panel shows the real BMP logo in our local side.
Best Regards,
George
