Users can use a custom Boot-Logo to replace default Khadas Boot-logo, there we talk about U-Boot stage logo, which will be displayed first after reboot.
The U-Boot logo is located at /usr/share/fenix/logo/logo.bmp.
The image format is BMP with a resolution of 500x500px and a bit-depth of 24 bits.
You can use Terminal to check the default logo image format:
$ file /usr/share/fenix/logo/logo.bmp
/usr/share/fenix/logo/logo.bmp: PC bitmap, Windows 3.x format, 500 x 500 x 24, image size 750002, resolution 2834 x 2834 px/m, cbSize 750056, bits offset 54
You can replace the default logo with your own BMP image.
$ adb root $ adb remount $ adb push xxx.bmp /mnt/vendor/odm_ext/logo_files/bootup.bmp $ adb shell sync $ adb reboot
