We are using Toradex Apalis imx8 SOM and the Yocto Project. We are using a standard HDMI monitor as the display output device.
I would like to know the steps/procedure that I can follow to enable the bootup logo and splash screen using Yocto recipes. I have gone through many posts related to splash screen(s) but they are mainly concentrated on Torizon core.
Currently, I don’t see any logo (even the default logo) while booting up, instead, I know a boot log on the HDMI display.
uboot setup arguments are currently set as “setup=run loadhdp; hdp load ${hdp_addr}; run mmcargs”
Standard 224-color Linux logo is enabled in manuconfig under Bootup logo settings.
I am using toradex dunfell branch to build my yocto project
Welcome to toradex community.
You can add a splash/boot screen to yocto recipe in various methods like patching,adding custom defconfig,or altering the kernel config options etc.
Hereby i’m attaching the steps to do the same
1.Create a custom meta layer and kernel recipe(recipes-kernel) as described Here
2.Now add 224-logo(logo_custom_clut224.ppm) file to recipes-kernel/linux/linux-toradex directory.Steps to create custom Splash logo
3.Add the changes in the kernel bbappend file.provided sample file(linux-toradex_5.4%.bbappend linux-toradex_5.4%.bbappend (669 Bytes)
).you can add the addition patchs here if needed.
4.Now build the custom image.
For u-boot splash logo,add the patchs to u-boot append file i.e recipes-bsp/u-boot/u-boot-toradex_%.bbappend
I followed all the steps that you suggested but I don’t see the logo appearing while booting up.
I am not even seeing a default Linux logo appearing on the HDMI monitor while booting.
Hope you have disabled the framebuffer console in u-boot.if not please use the below command to disable the same. setenv setup ‘setenv setupargs console=${console},${baudrate}n8 ${memargs} consoleblank=0’ setenv defargs consoleblank=0 vt.global_cursor_default=0
HDMI monitor is blank until kernel boot is completed. I see the DEMO QT application on the monitor after booting up, until then I don’t see anything on the HDMI display (monitor)
