1. Does /dev/ttyAMA0 exist?
2. Is UART0 (/dev/ttyAMA0) used for anything else? Most probably Linux console or serial.getty or something like this? Usually, I keep UART0 free for a Linux console and use one of the other 4 UARTs for things like gpsd etc.
3. apt install picocom and start it: picocom -b 9600 /dev/ttyAMA0 You should see lines of NMEA strings.
