Hi,

I was wondering if the atmega2560 is programmable using the FT232R. I have put the Mega bootloader on a blank chip and tried to upload but to no avail. I can write HEX files to it in AVR Studio but I cannot in the Arduino IDE using Serial. Is there something I am missing?

Did you burn the Arduino bootloader into the chip?  That's a necessary first step.

Yes I can confirm that I did burn the bootloader. I burnt it on the chip using avr studio and a mkii programmer.

Just two things are needed for serial programming: 1. the bootloader and 2. simple circuit which ensure chip reset and download. Provide details about your setup: circuit, bootloader (which exactly).
