Dear Sirs
I have a problem communicating with Atmega48.

ATmega32 programmed without any problem
avrdude -c usbasp -p m32

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.01s

avrdude: Device signature = 0x1e9502

avrdude: safemode: Fuses OK (E:FF, H:C9, L:EF)

avrdude done. Thank you.


If I try to Atmega48P


avrdude -c usbasp -p m48p

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

and

avrdude -p m48p -c usbasp -F

avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x88d692
avrdude: Expected signature for ATmega48P is 1E 92 0A

avrdude done. Thank you.


Connections are correct
