Any help appreciated.

What controller is this?

are you sure it has a 2560 chip on it? (eg many GT2560 actually have a 1284p on them, which uses a different upload baud rate)

This error basically says It cant talk to a boot loader

there are 4 main options

1) there is no bootloader on the chip (many cheap board suppliers do this)
2) the boot loader is using a different baud rate or protocol, this would be unusual for a 2560 based board, very common for 644p and 1284p based boards
3) the board has a jumper to disable the auto reset so the boot loader isnt started. Check your board
4) your using the wrong com port.

long usb cable can cause problem. Try to use very short usb cable.
