Not me, but I have heard reports.  Usually a voltage mismatch.

You can't just cat/minicom the serial port?

And stty shows the proper speed/framing?

Why would it run out of satellites?  Forget to charge them up?

Wierd.

Adafruit Pi GPS HAT -- serial port stuck

2022-07-08 Thread Hal Murray via devel


Has anybody seen the serial port get stuck?

It's software/kernel.  I can see the bits with a scope.

It works as expected until it runs out of satellites.  Then, sometimes it 
doesn't recover.

Restarting ntpd doesn't fix it.  Rebooting does.
