mantouboji Posted May 31, 2021 Posted May 31, 2021 I usually attach a GPS module to OrangePi One to act as a GPS ntp server . GPS serial data can use any UART port. but PPS pulse can use PA7 or UART_RTS, I most connect to PA7, works very well. Recently I bought a GPS modules for Rasberry Pi, it connect the PPS to pin 12, in One it's PD14 But when I set param_pps_pin=PD14 in armbianEnv.txt , it can't work at all . see /sys/kernel/debug/gpio , there is no GPIO 110 (PD14) at all. So don't use PD14 as a PPS pulse input.
