LCD Splash Screen

[Edd98]

I have been following BZT's tutorials, but adapted them for the Rpi 4, and have reached the stage where an image is being drawn to the screen successfully...

However, when the Pi is powered, the display turns on and immediately presents a splash screen with the display manufacturer's logo on... This is intended to be an embedded system and therefore I would like to remove this... I have tried the usual fiddling with cmdline.txt and config.txt with no luck and therefore I suspect it may be stored in the display's driver board?

Has anyone achieved anything similar?

disable_splash=1 from https://www.raspberrypi.org/documentati ... xt/boot.md should disable the rainbow screen

DISABLE_HDMI=1 from https://www.raspberrypi.org/documentati ... _config.md should disable the screen with the pi logo your seeing

I’m not seeing either the rainbow screen or the raspberry logo... I’m just seeing “elecrow” come up on the screen as soon as it is fed power... it lasts a few seconds and is then replaced with the picture drawn by the program...

You'll need to contact the display manufacturer, the bootloader doesn't initialise the HDMI block if DISABLE_HDMI=1 and there are no DPI or DSI drivers in the bootloader.
