program atmega8a using arduino as isp

bharathram · June 21, 2015, 4:48pm

i uploaded arduino isp on my arduino(atmega328p)... and i have hex file generated from winavr...i connected vcc,gnd,reset,MOSI,MISO,SCK pins of both arduino(programmed as isp) and atmega8....

and typed in cmd

C:\Users\ADMIN>avrdude -p atmega8 -P com11 -c arduino -U flash:w:main.hex

avrdude: Device signature = 0x1e950f
avrdude: Expected signature for ATMEGA8 is 1E 93 07
Double check chip, or use -F to override this check.

avrdude done. Thank you.

i got the signature of atmega328p not atmega8 y?? i didnt programmed bootloader on atmega8 becoz i'm using win avr not arduino IDE is this ok?

Try something more like avrdude -p atmega8 -P com11 -c stk500v1 -U flash:w:main.hex
What you are getting is avrdude talking to the 328 in your arduino, not the mega8. The 'arduino' protocol talks to the bootloader. The stk500v1 protocol talks to the ArduinoISP code.
