4 Zero W's boot but can't connect to them

[AJ]

Hi,

I am running RPI4 (8GB mem) with a clusterhat v2.5 and 4x Zero W's.

I followed the "Simple guide". The images I used were

RPI4 (control) : 2022-04-04/2022-04-04-2-bullseye-ClusterCTRL-arm64-CNAT.zip

P1 : 2022-04-04/2022-04-04-2-bullseye-ClusterCTRL-arm64-lite-p1.zip

P2 : 2022-04-04/2022-04-04-2-bullseye-ClusterCTRL-arm64-lite-p2.zip

P3 : 2022-04-04/2022-04-04-2-bullseye-ClusterCTRL-arm64-lite-p3.zip

P4 : 2022-04-04/2022-04-04-2-bullseye-ClusterCTRL-arm64-lite-p4.zip

I added /boot/ssh to those Px images for each Zero W to enable SSH.

I am using CNAT (FULL) because I am using WIFI on the control.

Powering on the hat, all yellow LEDs light up + each zero starts blinking green, eventually having the green LED blinking. But none of the Px's are pinging.

Here is an ifconfig -a output on the control

Before adding the 4 Zero W's, I booted the RPI4 with CNAT image. At that time, I changed the username to ei. Then I added 4 Zero W's.

I don't see any /dev/ttyACM or ttypi

ei@cnat:~ $ ls -l /dev/ttyACM*
ls: cannot access '/dev/ttyACM*': No such file or directory
ei@cnat:~ $ ls -l /dev/ttypi*

Any suggestions?

I used a wrong image. I needed to use 32bit image. With 32bit images, it is working fine.

Thank you

I thought I read somewhere that you can use the 64bit images on the Pi Zero but it failed to work for me too.

Hi,

I thought I read somewhere that you can use the 64bit images on the Pi Zero but it failed to work for me too.

The 64-bit images can be used on Pi Zero 2 W but not the original Pi Zero 1.x models.

Chris.
