w1_master_driver w1_bus_master1: Family 0 for 00.200000000000.23 is not registered.

After installing the new Raspbian strecht (2017-08-16-raspbian-stretch.img) I started seeing these messages in /var/log/syslog:

Code: Select all

Also a recent apt upgrade didn't change the situation. My current kernel is

What do these messages mean?

Do you have any 1-wire devices connected to your Pi (DS18B20 temperature sensor for example)?

If so, they are not connected correctly as the Pi is not detecting any. Those messages appear when no sensors are connected.

If you don't have any sensors connected you can ignore those messages, or disable the w1 (1-wire) driver in raspi-config or the Pi configuration program to get rid of them.

No, I don't have any of those devices.
But seems like this driver is enabled by default and looking for devices.
Is this really a good idea or just adding another source of failure?
At least it shouldn't report errors if no devices are found, which is the most common situation, and its origin should be more clear.

How can I disable this driver then or at least its alarming error messages?

Thanks, I found the entry in raspi-config (Interfacing Options=>1-Wire), but I would also like to know what changes raspi-config is actually doing so that I can use it in my raspbian config script.

Looking at /usr/bin/raspi-config it seems to be commenting in or out

Code: Select all

dtoverlay=w1-gpio
in /boot/config.txt

Is this all?

Yes as far as I know that's all it does.

Great, the error went away after commenting out the above line.
This configuration should be the default!

As I remember it was the default to have all interfaces off in raspbian Jessie, guess its another change that was made in stretch but as to why I have no idea. :?

I have requested this to be changed here:

I hope it is the right place.

Thank you.

And as it turns out, it is not in the default config.txt of the fresh Raspbian images.
In my case it must have gotten there somehow by accident ...
