I just had the Pi on my main control system crash. Looking through
syslog there are load of entries like -
Apr 20 14:47:35 pi-solar kernel: [1816089.721179] w1_master_driver
w1_bus_master1: Family 0 for 00.c61100000000.3f is not registered.
Apr 20 14:48:00 pi-solar kernel: [1816114.723725] w1_master_driver
w1_bus_master1: Family 0 for 00.261100000000.d6 is not registered.
Apr 20 14:48:51 pi-solar kernel: [1816165.440416] w1_master_driver
w1_bus_master1: Family 0 for 00.a61100000000.5a is not registered.
I think this is 1-wire related
My setup is a Sheepwalk RPi3 and splitter, with about 30 DS1820 temp
sensors and 7 DS2413 I/O boards, Pi and 1-wire are separately powered by
Meanwell units
I have rebooted and it seems to be running OK, but checking syslog again
I see
Apr 20 14:17:25 pi-solar kernel: [ 20.147355] w1_master_driver
w1_bus_master1: w1_search: max_slave_count 64 reached, will continue
next search.
and then there are more like -
Apr 20 15:26:42 pi-solar kernel: [ 261.951010] w1_master_driver
w1_bus_master1: Family 0 for 00.200000000000.23 is not registered.
Apr 20 15:27:45 pi-solar kernel: [ 325.543636] w1_master_driver
w1_bus_master1: Family 0 for 00.a00000000000.af is not registered.
Apr 20 15:28:23 pi-solar kernel: [ 363.463636] w1_master_driver
w1_bus_master1: Family 0 for 00.600000000000.65 is not registered.
I confess I don't understand the messages, could they be the cause of
the crash? Is there a problem with my 1-wire?
As always, I would be most grateful for any help and guidance.
Mick
