I recently purchased the following from CORE Electronics:-
PI Moroni Cluster Hat
4 x PI Zeros
After setting it up I found issues with the system.
I found the following appeared to work:
I can use the following quite successfully:
clusterctrl on p1
clusterctrl on p2
clusterctrl on p3
clusterctrl on p4
These all appeared to work okay, in that the PI Zeros turn on and appeared to boot their respective micro sd cards.
I also found the reverse of these also appeared to work:
clusterctrl off p1
clusterctrl off p2
clusterctrl off p3
clusterctrl off p4
Where the problem comes in is when the PI Zeros are ON, I was NOT able to connect to them i.e.
sudo minicom pi@p1
sudo minicom pi@p2
sudo minicom pi@p3
sudo minicom pi@p4
In each case above they connect to Port /dev/tty8 I would expect to see a login prompt allowing me to log on to the relevant PI Zero, so I could then run “sudo raspi-config”
However, instead I end up with a Frozen screen and no ability to communicate to the PI Zeros.
I contacted CORE-Electronics who advised me to return the Cluster Hat.
CORE-Electronics tested the Cluster Hat and found it was faulty.
CORE-Electronics replaced the Cluster Hat, so I have a brand new Cluster Hat.
Here’s the problem. I setup the PI 3B+, The NEW Cluster Hat and the 4 PI Zeros.
Problem: I get exactly the same result. I CANNOT communicate with the PI Zeros.
Minicom yields nothing more than a frozen screen.
CORE-Electronics have advised me to contact you guys.
My concern is, that the first faulty Cluster Hat has caused some sort of issue / damage to the 4 PI Zeros that were connected to it.
Are you guys able to help me with this?
Can anyone help me with this? I’ve had the product now since July and I can’t get it to work.
