bootloading a ATMEGA 2560

Other Hardware 3rd Party Boards
1

hi,

I would like to load the boot from arduino onto an ATMEGA 2560.

however after a lot of tries and research on the internet, I've got no results.

I keep on having the following message during the loading :

avrdude: verification error, first mismatch at byte 0x3e000
0x0d != 0xff
avrdude: verification error; content mismatch

any ideas how can I do that ?

I'm trying to load the boot with an other arduino ( I've got a MEGA and a UNO) withe the Arduino IDE.

I made my own board composed of a FT232, a quartz, an Atmel 2560 and some componants, and an ISP connector.

I've followed this thread :

Open the ArduinoISP firmware (in Examples) to your Arduino board.
Note for Arduino 1.0: you need to make one small change to the ArduinoISP code. Find the line in the heartbeat() function that says "delay(40);" and change it to "delay(20);".
Select the items in the Tools > Board and Serial Port menus that correspond to the board you are using as the programmer (not the board being programmed).
Upload the ArduinoISP sketch.
Wire your Arduino board to the target as shown in the diagram below. (Note for the Arduino Uno: you'll need to add a 10 uF capacitor between reset and ground.)
Select the item in the Tools > Board menu that corresponds to the board on which you want to burn the bootloader (not the board that you're using as the programmer). See the board descriptions on the environment page for details.
Use the Burn Bootloader > Arduino as ISP command.

But it's giving just errors .

(BTW please tell me there is a solution to get the boot on this chip)

here is the board i've made

I've disconnected all the other electronics around.

about the arduino,
for the uno, I've connected the 7,8,9 to LEDs; then I've matched my isp connector and the pads from the arduino (MISO,MOSI, SCK)
I've connected the RESET of the ISP to the pin 10 and the vdd to the 5v from the arduino.

The reset of the uno (programmer) is connected through a resistance to the 5V ( or through a capacitor, 'cause I've found both solutions)
