The only ugly thing is that they have removed the logos, the open hardware logo and the CC BY-SA license and give no credit to the source at all, but...


You could file a DMCA complaint :-)

Also, I hear they deal very harshly with copyright infringers in China. At least, that's what their government says.


:)

It is just a simple gesture to say it is an open sources desig and give credit to the authors. No big deal. Any way the design was there to use, sell, what ever.

  Has anyone been able to burn a bootloader to the 32u4 using an Arduino Uno as ISP?

I have had my two little Leos soldered for a while but, have just now tried to install a bootloader and drivers. To make a long story short I can't seem to get the Leonardo bootloader to install. The closest I got was the IDE saying I had an invalid chip signature. I have done several bootloads before so, I think my problem is in my IDE files.

I am using the lastest IDE 1.01 Arduino, and a Rev2 Uno to try to burn the bootloader.

Any help or experience shared would be appreciated.

I have not. I use an AVR ISP, no messing with setting an Arduino, just keep a tool handy instead.

Yes, there is a little tuto going for the vinciDuino as to how to "burn" the bootloader to the 32U4. It is in Spanish but you can invoke google translate to the rescue: http://vinciduino.com/esp/tutoriales

Thanks for the replys CrossRoads and FM

I followed the tutorial, downloaded a Aduino as ISP sketch, and loaded it to the UNO.  I got many errors when trying to do the upload. I think most of the errors referred to missing board/chip information.

I will keep trying.

this is an extremely unlikely reason, but since Arduino ships with an older and custom compiled version of WinAVR, maybe it's too outdated for this chip?

Yes, one of the things that you have to make sure off is that you are using IDE v1.0.1. In the Spanish section, a wide range of users have reported to be able to upload the bootloader to the vinciDuino under: windows, linux and OSX.

Really?  I thought it was standard, except for avrdude...

Yeap Arduino 1.0.1 works great for burning the bootloader to the 32u4, use it to upload to my pH unit and every once in a while the leonardo board I made.
