Pololu USB AVR
The Pololu USB AVR Programmer Version 2.1 is a versatile and reliable interface device that programs ATMEGA AVR devices.
Install
Fetch required binary archive for your computer system and install the utility software to control the special features of the programmer.
Avrdude will be used to perform the actual programming once everything is setup.
tar Jxvf pololu-usb-avr-programmer-v2-1.1.0-linux-rpi.tar.xz cd pololu-usb-avr-programmer-v2-1.1.0-linux-rpi sudo ./install.sh
Test
Check that things are operating

pavr2cmd: Pololu USB AVR Programmer v2 Command-line Utility
Version 1.1.0
Usage: pavr2cmd OPTIONS
General options:
-s, --status Show programmer settings and info.
-d SERIALNUMBER Specifies the serial number of the programmer.
--list List programmers connected to computer.
--prog-port Print the name of the programming serial port.
--ttl-port Print the name of the TTL serial port.
-h, --help Show this help screen.
Options for changing settings:
--regulator-mode MODE Sets programmer's operating voltage.
auto - choose 3.3 V or 5 V based on target VCC
3v3 - always 3.3 V
5v - switch to 5 V soon after power up
--vcc-output OPTION Choose whether the programmer supplies power
to target VCC. Options: enabled, disabled.
--vcc-output-ind OPTION Sets how to indicate that VCC is an output.
blinking - yellow LED(s) blink at 8 Hz (default)
steady - yellow LED(s) are on constantly
--freq NUM Sets the ISP frequency (in units of kHz).
Must be typed exactly as shown below.
Suggested values: 3000, 2400, 2000, 1714
1500, 1200, 1000, 750, 444, 114 (default),
28.3, 14.0, 6.98, 3.47, 1.744, 1.465.
--max-freq NUM Sets the max ISP frequency (in units of kHz).
Must be typed exactly as shown below.
Suggested values: 3000, 2400, 2000,
1714 (default), 1500, 1200, 1000, 750.
--line-a FUNC Set the function of line A. Valid FUNCs are:
none, cd, dsr, dtr, rts, dtr-reset.
--line-b FUNC Set the function of line B. Valid FUNCs are:
none, cd, dsr, dtr, rts, clock, dtr-reset.
--vcc-vdd-max-range MV Sets the maximum allowed range for VCC and VDD
while programming.
--vcc-3v3-min MV Minimum allowed VCC while programming at 3.3 V.
--vcc-3v3-max MV Maximum allowed VCC while programming at 3.3 V.
--vcc-5v-min MV Minimum allowed VCC while programming at 5 V.
--vcc-5v-max MV Maximum allowed VCC while programming at 5 V.
--sw-minor HEXNUM Set STK500 software version minor (in hex)
--sw-major HEXNUM Set STK500 software version major (in hex)
--hw HEXNUM Set STK500 software hardware version (in hex)
--restore-defaults Restore factory settings
This utility only supports the Pololu USB AVR Programmer v2
(blue-colored, labeled "pgm04a").
MV should be a voltage in millivolts. For example, "3400" means 3.4 V.

Usage
The programmer can either be used in ISP STK500 mode else as a serial UART for a bootloader.
Query a MEGA2560 connecter by ISP.
avrdude -B 5 -c avrisp2 -P `pavr2cmd --prog-port` -p m2560
