Matrix Voice 1 panic'ed (IntegerDivideByZero)

[jlaba]

Following the Readme I uploaded the firmware to my matrix voice. Connected with minicom to /dev/ttyS0 it shows a reboot loop with the following output:

`LF file SHA256: 0000000000000000

To setup the environment on the PI I have used this repo https://github.com/qnlbnsl/Matrix-IO since the matrix.io repos are offline. (See separate issue to add a hint to your Readme file for that).

Is the hostname in the MQTT section your IP or the value MY_IP?
Don't know if that is the issue by the way.
And maybe edit you passwords out ;)

Good tip :-) (passwords)

The hostnae is my mqtt ip address.
