8 UART(TTL/232)A is a DEBUG port, all TTL is 3.3V
If you want to use GPS Sync function, please refer to the following instruction:
Connect GPS NMEA Serial port to UART(TTL/232)B port of Apex Xavier(Baud 9600), device node is /dev/ttyUART_TTL_232_B
Connect GPS PPS Port to SYNC_IO PIN1of Apex Xavier, device node is /dev/miivii-sync-in-a
These two nodes above is occupied while GPS Sync function is available.
