Hello Guys,

I'm using Atmega328p to burn bootloader with arduino UNO , But when i'm burning bootloader(Arduino as ISP) , It appearst his error "
avrdude: Device signature = 0xff0000
avrdude: Expected signature for ATmega328P is 1E 95 0F
Double check chip, or use -F to override this check.
Can someone help me please!!!!

couple of different things can cause this problem. I assume you tried switching the TX/RX connections. It's possible (not likely) that the resistor you use to pull up the reset pin on the target chip is too small or too big. In my experience, the most common culprit is loose wire connections or poor soldering on the target board.

Show us the connections between Uno and 328P. Like other said, Device signature = 0xff0000 means Uno cannot communicate with target. I assume you are using ICSP header to burn bootloader, so check all pins.
