How to customize openstlinux boot screen (psplash)

[hochul yoo]

I am evaluate the STM32MP157C-DV2 board.

I have disabled the weston service by referring to the link below.

https://community.st.com/s/question/0D53W00000cSKmXSAW/disable-weston-autostart-in-stm32mp157cdv2

​

When boot with the weston service disabled

The two images below appear sequentially.

​

I want to customize the boot screen to the image I want.

I found the above images in the path below.

layers/meta-st/meta-st-openstlinux/recipes-graphics/wayland/weston-init/

​

Although I did find the path of the default boot images,

I think it has nothing to do with weston-init because the weston service is inactive.

The psplash recipe exists in the path below.

layers/meta-st/meta-st-openstlinux/recipes-core/psplash/psplash-drm

layers/openembedded-core/meta/recipes-core/psplash

What recipe do I have to override in my custom layer to change the boot screen?

Hi,

first image is uBoot splash screen (splash.bin in bootfs I think)

second the Linux one

see section 7 in https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-DK2/Let%27s_start/Populate_the_target_and_boot_the_image

I'm not Linux nor Yocto expert, maybe this one could help:
