So I built a dedicated one with a Teensy 2 or 3 and a 8-SOIC chip-clip. The entries are new to me, but the only goal is to use arduino as protocol because you are on windows.Like ho.ax, I had been using a Dangerous Prototypes buspirate to read SPI flash boot ROMs, but it was too slow. Instead, directly modify arduino-1.5.2/hardware/arduino/avr/programmers.txt: change these items: arduinoisp.protocol=stk500v1Īlso make sure the baud rate is correct (19200). Remove the "leofix" (remove again the hardware directory from your sketchbook directory). The ide does not care your programmer happens to run on a Due.Ģ. Leave the "leofix" in place and burn the bootloader using ide 1.0.3 or higher. Now, about the call stack trace: I remember some issues being reported with the way 1.5.2 deals with sketchbook directories.ġ. Very important: never plug in the Leo's usb port while this wiring is in place (Leo powered by the Due's 3V3) ! Anyway I experienced no neagtive effect of it. From the schematcs of the Leonardo, I don't see a problem with this, but of coarse I might overlook something. I found it an intuitive way to power the atmega32u4 at 3V3.

Not sure how to interpret this, but I meant following: Pin Due | Pin Leonardo I want to avoid someone damages his or her Due because of reading this thread. I would love to say: IT s working Jipppii, but i cant. The PC can`t connect all the way to there arduino leonardo(Atmega32u4 chip) board

I would be very pleased if you could help me, thank Well an error appeared: "avrdude: stk500_getsync(): not in sync: resp=0x00"

(if that works I guess it`s pritty strait forward?!) Now I wanna take a step back and try to reload the bootloader onto the Leonardo board.

I am trying to load the leonardo bootloader to an AtMega32u4 but that doesn`t work out.
