Hello @MFR ,
The uboot splash screen is enabled by default when you generate image by yocto. if your question is about the customization of the splash screen, you need to update the recipe meta-st-stm32mp/recipes-bsp/u-boot/u-boot-stm32mp-splash_2018.bb and add your images in the directory layers/meta-st/meta-st-stm32mp/recipes-bsp/u-boot/u-boot-stm32mp-splash. So, you can customize it as follow:
- Generate bmp images using convert (images dimension must be 480*183 or 183*480) :
convert your_logo_l_rgb_rle8_480x183.jpg -type Palette -colors 224 -depth 8 -compress none -verbose BMP3:your_logo_l_rgb_rle8_480x183.bmp - Copy your splash images (bmp) under meta-your-layer/recipes-bsp/u-boot/u-boot-stm32mp
- Create meta-your-layer/recipes-bsp/u-boot/u-boot-stm32mp-splash_%.bbappend
- Copy the following content in your bbappend file:
FILESEXTRAPATHS:prepend := "${THISDIR}/u-boot-stm32mp:"
SRC_URI = "file://${UBOOT_SPLASH_LANDSCAPE_SRC} \
file://${UBOOT_SPLASH_PORTRAIT_SRC}"
UBOOT_SPLASH_LANDSCAPE_src="your_logo_l_rgb_rle8_480x183.bmp"
UBOOT_SPLASH_PORTRAIT_src="your_logo_p_rgb_rle8_480x183.bmp"
