Summary0002971: Rocky 8 uart serial console configuration missing/incomplete
DescriptionWhen attempting to use the implemented console configuration provided, the console port selected is incorrect. Also uart is not enabled although a console is setup.
Steps To Reproduce- attach uart cable (I'm using the ADAFRUIT Industries 954 USB-to-TTL Serial Cable)
- start uart session on client (screen /dev/ttyUSB0 115200 on connecting host)
- boot Raspberry Pi using Rocky Linux RockyRpi_8.7.img installed on usb storage

Result is no console output is produced on the console session.
Additional InformationThe following changes followed by a reboot resolve this issue for me:

Update /boot/cmdline.txt:
console=ttyAMA0,115200 console=tty1 root=PARTUUID=13381799-03 rootfstype=ext4 elevator=deadline rootwait
console=serial0,115200 console=tty1 root=PARTUUID=13381799-03 rootfstype=ext4 elevator=deadline rootwait

Create /boot/config.txt and adding the following:
