I'm new to the Orange Pi 4 LTS. I work SBC's headless and have installed using UART many times on RP Zero's, BananaPi's and most recently on a RockPro64. However, I am not sure if I should be using. Is there another set of UART pins besides the "debug ins"? Booted the image on an sdcard connected to the debug pins and just got 8 lines of this stuff <��6v��Ή9�.�����goO
