I am trying to read the fuse values for the Arduino Uno, but keep getting the following results returned back to me:

avrdude done.  Thank you.

I have tried using avrisp as the programmer too, but this reports an invalid device signature. If I override the device signature check with -F I get the same results as above.

I am using an Uno as the ISP to another uno and have connected the two together as detailed in https://www.arduino.cc/en/Tutorial/ArduinoISP

I have boot loaded the Arduino Atmega328P boot loader and from the fuse settings given in the boards.txt file expect to see: lfuse reads 0xff hfuse reads 0xde efuse reads 0x05

Another question is with the low fuse set to 0xff the CKDIV8 is programmed so won't the clock be set to 2MHz?

Please help

CKDIV should be 0 to enable the divide by 8. Since it's set to 1 the clock frequency will be 16MHz (when using a 16MHz crystal, that is). – Gerben Nov 13 '16 at 9:46
    
Did you do step 5 (Note for the Arduino Uno: you'll need to add a 10 uF capacitor between reset and ground.)? – Gerben Nov 13 '16 at 9:48
    
I connected a 10uF cap between rst on the board to be programmed and the GND on the ISP board – Danny J Nov 13 '16 at 9:50
    
RE CLKDIV8 thanks for clearing that up – Danny J Nov 13 '16 at 9:53
