I am planning to develop ethernet bootloader. So I wanted to modify the existing DFU Bootloader program. I want to delete the already existing bootloader on micro-controller flash and put my own bootloader.
Currently my MCU is AT32UC3A0512. I am using AVR Dragon and AVR One debugger/programmer. Is it possible to reprogram the bootloader region with AVR Dragon or AVR One? or I must need to have MKII debugger?
