Re: i2c-tools & serial port

[ng0177@xxxxxxxxx]

Good advice. I tried but adding the uart option didn't work. I suspect we have two problems overlaid. It coudl be a problem with the python version in addition?

$ sudo i2cset -y 1 0x60 0x08 0xbb && sleep 1 && sudo python PCF4_serial0_9600_FU1.0.py -v -f PiCoolFAN_V1_4.hex
  File "PCF4_serial0_9600_FU1.0.py", line 120
    print 'WARNING: I2C support is missing. Please install smbus support for python to enable additional functionality! (sudo apt-get install python-smbus)'
          ^

You can enable the serial port by adding this line:

enable_uart=1

in the file /boot/efi/config.txt and rebooting the Pi.  If that doesn't work for you, you might consider temporarily loading a copy of Raspbian on an SD card just to do the fan setup, since that is what the hardware manufacturer expects you to be using.

After configuring the fan, then put your Fedora SD card back in.  The manual you linked to says that the settings are stored in EEPROM, so they should be remembered when you switch back to Fedora.
