Running RPI2 with a clusterhat v1.2 and 4xZeros (1xv1.2 and 3xv1.3).
Following the "Simple guide", I have written the latest (2020-12-02) Buster images for each Zero (with enabled SSH) and tried both CBRIDGE and CNAT (FULL) on the RPI2.
Powering on the hat, all yellow LEDs light up + each zero starts blinking green, eventually having the green LED on full time.
Running ifconfig does show the brint interface as 172.19.180.254 but trying to ping 172.19.180.1(2,3,4) returns that the host is unreachable.
pi@cbridge:~ $ sudo brctl show return:
bridge name bridge id STP enabled interfaces
br0 8000.b827eb0e7648 no eth0
brint 8000.000000000000 no
lsusb -t return:
pi@cbridge:~ $ lsusb -t

I don't see the zeros in my router DCHP table either.
