The HAT connects to the UART pins (GPIO14/15) to communicate serial data such as GPS time and location. chrony should be able to use this data to set the system clock.as the hat was connected over GPIO8 & 10 UART, where as the links was using diff gps module and pi3.
The pps-gpio overlay needs a one pulse per second signal on a different, non-UART pin. This does not tell you what the time is, but it allows chrony to measure the start of each second much more accurately than over serial. You probably do not need this, unless you plan to use the Pi as a high stability time source.
Looking at the schematic for the HAT, the 1PPS signal appears to be connected only to an LED, not to the Pi. So it would need a fine soldering modification to add the functionality anyway.
Do you mean that only SSH is not working, or that the Pi is not booting at all now? Does not seem related to what you did, either way.After editing the /boot/firmware/config.txt and /boot/firmware/cmdline.txt and reboot, im unable to ssh into my device.
