I have atmega1281 and AD-USBISP V03.6
I have compile problem write on flash
problem is
sudo avrdude -p m1281 -P /dev/ttyUSB0 -c stk500v2 -U flash:w:test.hex:i
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: AVR device initialized and ready to accept instructions
Reading | ################################################## | 100% 0.01s
avrdude: Device signature = 0xffffff (retrying)

avrdude: Device signature = 0xffffff (retrying)
Reading | ################################################## | 100% 0.01s
avrdude: Device signature = 0xffffff
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
first problem that I guessed is stk500v2_ReceiveMessage(): timeout
but I don't know how to solve this problem.
How to solve this problem and write test.hex on flash of avr ?
