  1. Hello. Somehow TX on UART 3 is not working. I connected USB-UART converter or the Banana Pi Zero M2 UART 3 Pins (as it shown here https://bananapi.gitbook.io/bpi-m2/en/bpi-m2_gpio_pin_define), set Baud rate, but I can't send anything from the SBC to PC. But I can send messages from PC to Banana pi. The converter is working properly(tested on Arduino). Do you have any ideas why? Physically nothing looks damaged, wires are soldered accurately and correctly.... Some system info $ uname -r 6.1.2-sunxi $ cat /etc/os-release PRETTY_NAME="Armbian 23.02.0-trunk Jammy" NAME="Ubuntu" VERSION_ID="22.04" VERSION="22.04.1 LTS (Jammy Jellyfish)" VERSION_CODENAME=jammy ID=ubuntu ID_LIKE=debian HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" UBUNTU_CODENAME=jammy $ cat /boot/armbianEnv.txt | grep overlay overlay_prefix=sun8i-h3 overlays=uart2 uart3
