I have Rock Pi S V13, that has 4 UART ports. I'm already connecting to the board via serial console on /dev/ttyS0. How can I find out what are the other ports assignments/paths? I have tried to use a Python script to detect the output by using an FTDI to USB board with no luck (the voltage and baudrate are correct). The Python script taken from manual: import serial import time # I've tried /dev/ttyS2 and /dev/ttyS4 ser = serial.Serial(port='/dev/ttyS4', baudrate=115200, timeout=0.1) print(ser.name) try: while True: ser.write(b'hello') time.sleep(0.5) except KeyboardInterrupt: ser.close() Running outputs and outputs

Upgrade install on Rock Pi S. No serial console with Focal Edge image.

After installing armbian-firmware-full, the bluetooth firmware gets loaded. Thank you!

The Armbian 22.11.4 Jammy with Linux 6.0.10-rockchip64 doesn't have the drivers for a USB Bluetooth bought from Amazon. The kernel gives me these errors at boot: Listing the available bluetooth drivers ls -l /usr/lib/firmware/rtl_bt gives me: while the latest Linux kernel contains the driver: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rtl_bt Where can I get it or how can I install the bluetooth driver?

I had the same issue with Nano Pi Neo Core, having shipped with Ubuntu 16.04.2 LTS from FriendlyArm and U-Boot SPL 2017.11 on flash. It seems that this version of U-Boot has a bug that does not allow you to boot newer OS from SD card. I have updated the U-Boot by booting Armbian_21.02.1_Nanopineo_bionic from SD card and running armbian-config and installing the OS to flash and updating U-Boot. Now I have U-Boot SPL 2020.10-armbian. While this is Ubuntu 18.04.6 LTS, I'm still unable to run the latest Armbian (Armbian 22.11 Bullseye or Armbian 22.11 Jammy).

On my NanoPi Neo Core, the flash has the following partitions: Most of the drives I've encountered have the starting sector set as 2048, while this one has 49152. I'm assuming that U-Boot reside before the 49152th sector. How can I see what is below 49152th sector in the partition table?
