I made many changes at same time (new enclosure, removing some packages, update packages, update firmware; can say shorter I have made great one day maintenance) and then RPI does not sees i2c bus (cannot measure pressure, light intensity and one wire temperature DS18B20). DHT22 WORKS .
After two days of finding bug in wiring, reinstalling packages and so on, I' ve got idea, new firmware... I have downgrade him and voala, everything WORKS like a CHARM.
magic command is (Linux raspberrypi 3.12.35+ #730 PREEMPT Fri Dec 19 18:31:24 GMT 2014 armv6l GNU/Linux):
I have better use 3.12.35+, because firmware 3.12.36+ have freeze me RPI one time.
Code: Select all
sudo rpi-update ba43047bec24d5f0a4150f09a37884240f8926d2
