Arduino Leonard Uploading issue

Hi All,

Recently I bought Arduino Leonardo board. I am using Aruino 1.0.1 sw ver, installed on Windows7 (x86 64bit). Driver installation took time and machine abruptly restart while installing HW. But now when I connect board to another USB port, it starts working. But while uploading sketch, it display below error:

"
Binary sketch size: 4,858 bytes (of a 28,672 byte maximum)
Found programmer: Id = "B¯b"; type =
Software Version = .; Hardware Version = .
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?
"
Could you please help me, why it is coming? How it get resolved? Any procedure to overcome the error?

Do you have the right type of board and serial port selected in the software?

yup i have selected same Leonardo H/w and respective port butit wont work. So i shifted to another machine which is having WinXP and it works smoothly... So right now I am using WinXP for programming.

Thanks for help

Hello, all
This is my first post.....
Just received my Arduino Leonardo an found the right micro USB cable and I tryed to upload the blinking sketch
I've got exactly the same problem but with WINXP SP3 machine.
I've checked PortCom (presently n°13 on my computer) and drivers seem well instaled.
Hope some one have the soluce.

Have you tried pushing the reset button on the board 5-8 seconds after clicking upload?

Thks for the answer.
I'd tried the reset trick. What I did to night is to change USB port and it works perfectly (it is now on USB3.0 port but the previous port was not an hub). I have tried changing the loop delay in "blinking" and it is OK.
Hope this can help.....
Ciao.

Picky ports, yet again. I have mine on a hub as well and it uploads well enough(no serial out though). If plug it onto the "Root USB", I have to use the trick because it just hangs.

Good luck!
