Boot logo?

[dmitryelj]

Hi all,

I want to show a bitmap logo when board power is on. I see some logos in 'tools/logos' folder, is it possible to enable it?

Ma I know the logo you want to show is at HDMI or DSI panel ?

Hi,

I'm trying to make the bootloader show a logo in the video connected via HDM, but I'm stuck.
This is what I've done untill now.

Create a patch for the bootloader where I've configured:
In configs/tinker-rk3288_defconfig add CONFIG_CMD_BMP=y
In /include/configs/tinker_rk3288.h add several defines
#define CONFIG_SPLASH_SCREEN
#define CONFIG_SPLASH_SCREEN_ALIGN
#define CONFIG_SPLASHIMAGE_GUARD
#define CONFIG_VIDEO_BMP_GZIP
#define CONFIG_VIDEO_BMP_RLE8
#define CONFIG_LCD_BMP_RLE8
#define CONFIG_CMD_BMP
#define CONFIG_SYS_VIDEO_LOGO_MAX_SIZE ((500 * 160 * 4) + 54)
#define CONFIG_BMP_16BPP
#define CONFIG_BMP_24BPP
#define CONFIG_BMP_32BPP

I flashed the image with the patched bootloader in the mmc, then stopped the boot sequence and execute those commands:
ext2load mmc 0:5 10000000 logo24bit.bmp
bmp d 10000000
But nothing happens on screen.

Then I've add some debug prints inside the bootloader code to catch the return value of the command but all seems to work correctly.
The function called by the bmp display command is cmd/bmp.c::bmp_display() and, since CONFIG_VIDEO is defined, drivers/video/video_cmp.c::video_bmp_display(). The the big switch inside the last function the case taken by my image is 24, that right becasue it's actuallly 24 bpp and the screen is 32 bpp and this combination it'supported. It seems to write the bmp data inside the fb(framebuffer) variable and then flush it calling drivers/video/video-uclass.c::video_sync() function. But nothing is show on screen.

What am I doing wrong?
Any suggestion?
