Urgent! Trying to use usbtiny ISP to flash a hex file onto the 16u2 chip of mega

Hi folks,

I am currently working on a MIDI controller prototype using Hiduino.
(GitHub - ddiakopoulos/hiduino: Native USB-MIDI on the Arduino).

I successfully managed to flash this firmware onto the 16u2 about a year ago (With great effort)
and now I have to do it again. The problem is I keep getting the following error:

My command is
avrdude -p m16u2 -P usb -c usbtiny -U flash:w:usbserial_mega_16u2.hex -v

and the response I get is:

avrdude done. Thank you.


usbtiny does appear to be working but it just wont communicate.
The mega is brand new :confused:

I am at my wits end having been trying to fix this for over 8 hours now

Try this to see if you are hooked up right.

avrdude -p m16u2 -P usb -c usbtiny

$ avrdude -p m16u2 -P usb -c usbtiny

avrdude: AVR device initialized and ready to accept instructions

avrdude done. Thank you

The ATmega16U2 supports DFU programming over USB. So you can just use Atmel Flip or dfu-programmer to flash the hex file.

Full instructions can be found here.

Kprims I did that and got the same result.
In the end I suceeded through the DFU method although when I try to rename the device it still enumerates as arduino_midi.

However the ISP works fine when programming the 2560 in the arduino IDE so I don't know what gives.

Did you compile the firmware yourself?

Pieter

Yes, Even had to install Gnu make for windows and mess with my path variables to do so.

Why is this urgent?

INTP:
Why is this urgent?

Because I am working on a project that I want to get to market.
At the time I was not able to get the firmware on the chip at ALL until I discovered the DFU method, and therefore couldn't proceed with my project
