Hi!

I have made my own pcb with a Atmega32u4 as processor. I used the bootloader from Sparkfun (Fio V3). I have a 3.3V power source, 8 Mhz Crystal and the USB-Port is wired just like on the Sparkfun Schematic.

I have "burned" the bootloader via SPI with an Arduino Uno - worked
I uploaded a few sketches to test the hardware via SPI (Upload using programmer) - worked, but it terrible slow!

What i can't do is using usb to upload. The Board is found in device mangaer as "Sparkfun Fio v3 (COM 15)". When power the board up, and then want to upload the skech, the board dissapers from the device manager.

In the IDE it just does:

Code: Select all

Sketch uses 20398 bytes (71%) of program storage space. Maximum is 28672 bytes.
Global variables use 497 bytes of dynamic memory.
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}
PORTS {COM1, } / {COM1, } => {}

A few times until a timeout occurs. The Board seems now "stuck", it don't does anything, it does not run any sketch and hitting reset will NOT do anything (neihter execute the programm nor reappear in the device manager).

I have to power down and power up again to fix this.

I tried to initiate Upload, then push reset down, and unpush just the moment it wants to upload, this does something, it starts something that looks like it trys to upload:

         Programmer Type : butterfly
         Description     : Atmel AppNote AVR109 Boot Loader

Connecting to programmer: .avrdude: butterfly_recv(): programmer is not responding

avrdude: butterfly_recv(): programmer is not responding

But then it stops

Any idea how to fix this?

I have solved this problem now, by using the "pro mirco" bootloader. That one works and fortunately the pins are all mapped too
