RPI4 uart problem

edited October 2021 in OS features
Goodmorning everyone. I am testing emteria on RPI4 -4GB hardware with official 7 inch touch display. Everything works but the display is very unstable, shaky. The notification "Serial console enabled Performance is impacted. To disable, check bootloader" appears, I disabled uart in boot configt.txt but on next reboot rainbow splash screen and then black screen. Any suggestions? Thanks sorry for the English


  • We don't know why UART is required for the official screen to work properly. Seems like it is a hardware thing. We'd be happy to disable the console globally.
