Hello, According to documentation, LuckFox Pico Pro/Max has 5 serial ports (one of them - UART2 is always used as debug console). I want to use the remaining 4 ports, but only 3 shows up (UART1, UART3, UART4). How to enable UART0? I tried luckfox-config, and also tried to manually edit /etc/luckfox....
