Firmware upload fails

Hexy Questions, Problems and Suggestions
#1

Hey,

Every time I am trying to upload any code through Arduion 1.0.5 I get this error:

Using Port : \.\COM3
Using Programmer : avr109
Overriding Baud Rate : 57600
avrdude: ser_open(): can’t open device “\.\COM3”: System can’t find given file

avrdude: Send: E [45]
avrdude: ser_send(): write error: sorry no info avail

My physical used com port is Com4 / com3 is only the virtual one
I am using Win 7 64 bit.

I am trying to solve this problem for quite some time now and I also manged to kind of get it to work through several times deleting and reinstalling all required software and updating drivers. (I managed to upload the firmware without any errors and also the blink example worked) but then I tried to run the PoMoCo and got error messages there (" Failed to connect to Servator. No movement will occure. ")
So I looked this up in the forum - there hasn’t been any real solution, but it was recommended to restart the computer - so I did - well and now nothing is working again…
Please can someone tell me what to do…

Be sure to press the little reset button on the Hexy microcontroller board just before you start the download to it from the arduino API. It took me a few times before I figured that out. Good luck!

thanks for your answer but I press the reset button.

Here’s how the Arduino software usually loads a program:

1.) Send a signal to the board to reset to the bootloader
2.) Arduino software waits for the USB connection to reset because the board switched to bootloader
3.) Board is now in bootloader
4.) Arduino software sees new USB connection, sends what it supposes is the bootloader a new program
5.) Bootloader re-writes the program space with the program the Arduino software just sent it, then runs what it just wrote

Here’s how you should be able to do an upload ‘manually’:

1.) Hold the reset button down, don’t unpress it yet
2.) Press upload on the Arduino software, and wait for a second after it shows "uploading code"
3.) Unpress the reset button, this acts as the “reset” the Arduino software is waiting for
4.) The Arduino software should now load a new program, and the bootloader should run it.

i have kind of the same problem, the Arduino IDE won’t upload the code: it just says uploading the entire time… until at a certain point it gives this error:Found programmer: Id = “B©J”; type =
Software Version = . ; Hardware version = .
avrdude: error: buffered memory acces not supported. Myabe it isn’t
a butterfly/AVR109 but a AVR109 device?
i press the resetbutton, then i upload the program, just like instructed above.

I had a similar problem and only got my device working when I held down the reset button and released the button at the right time (step 3)
