Troubleshooting • PI5 Debug UART not working on new install

$

Hey guys, noob question here, but on a fresh install of Rasdebian on a Pi5, the debug UART port is not outputting any information on boot, and is not providing a terminal once the system has fully booted up, its as if the UART is not enabled. I tested my UART-USB dongle with HW loopback and it is working properly. I also tried modifying the config.txt to enable UART0 based on the raspi-config online documentation. Is there something I am missing. What I would like is for the debug UART to provide the linux shell on boot to facilitate provisioning and configuration. I am sure its a simple thing I have missed.
