Pi crashes randomly when change GPIO

---

Hello,
i’m running the lasted version of pimatic on an old Pi B1. I have connect 6 of 8 relays of a china relay board to the followings GPIOs

The Pi is driven by a 2,5A 5v power supply. The relay JD-VCC of the relay is connected to the same power supply.
If i change the state of a gpio my Pi randomly crashes. Sometimes i can switch on/off 2-3 times, but then the Pi does not response (can’t limit to one specific GPIO).
No entry in message.log / kernel.log / pimatic-daemon.log
Currently i don’t have any VGA output, only SSH access via WiFi stick.
PING is lost instandly. Power off / On requiered.

Any Ideas?

did you try to use another power source for the relay?

Yes, just 3 min ago.
Seperate power supply for pi / relay board.
I switched 4-5 gpio’s fine, then pi crashes (ping lost, pimatic not responding).
I will connect a monitor later this day to see if there is any kernel message.

Connected Monitor and Keyboard.
This morning it happend at the first switch:

Freeze. No Kernel Panic. Nothing.
I did a tail -f pimatic-daemon.log, switched the first gpio -> freeze.
I had to remove power to reset.
The pi was running with domoticz and a 4way relay for over a year.
Last week i reinstalled the pi with the lasted raspian image, replaced the 4way to a 8way relay and installed pimatic.
The Pi is installed in on a din rail and powered by this power supply:

Edit: I installed wiringPi. Could this be a problem?

Even on command line it crashes…

did you maybe wire the new relay board incorrectly?
To me this sounds like the gpio you try to switch is connected to ground and you are causing a short circuit by triggering it which crashes the PI

I changed some cabeling, specially the GND.
I have to check and do some add. testings. Will report later

Hey,

That would be interesting to know.
I changed my Pi from a Pi B to a Pi 2. I have also a china relais board and on the old pi there were no problems, but now the Pi 2 crashes randomly.

If you supply the relay board with a seperate power supply you have to set a jumper on the relay board, have you set this correctly?

I powered the relay board seperated, i powered it via Pi. Check cabeling.
It worked for some switches, and then it still crashes.
This morning i ran pi update and updated my kernel…
