My question about bootloader information is still relevant, but my suspicion is that it is the 8u2 that we're running into here, not the bootloader (yet).</div><div style><br></div><div style>Cheers,</div><div style>Matt</div>

<br>
I just found the plumbing and Occam-pi programming environment for arduino, and it seems to be just what I need for my project. So I tried to install the Software but without any success. Here are the details:<br>
<br>
My System: Ubuntu Linux precise/amd64. The Arduino-IDE works great with<br>
my Arduino: Sainsmart Mega 2560<br>
<br>
<br>
Here is what I tried to get Occam-pi to work.<br>
<br>
First get the whole thing in my native system: No chance, because of the amd64 platform doesn't allow to install the i386 version of many libs without throwing many applications away.<br>
<br>
So I set up an i386-chroot. The Occam-pi environment installed flawlessly, but couldn't get the firmware on my Arduino.<br>
The error-message I got is the same as Christian Lewis gets on his system:<br>
<br>
Uploading Plumbing firmware<br>
avrdude: stk500_recv(): programmer is not responding<br>
<br>
<br>
After that I tried to install the Windows-Version running on a Virtualbox Windows XP (32) System. There the error message was that avrdude couldn't sync with the Arduino. The Arduino-System could upload a sketch to the Board under Windows, but got a checksum error after uploading the sketch.<br>
<br>
Ah, and yes, I tried many times the uplaod process, disconecting the Arduino in between and reseting it very often.<br>
<br>
<br>
Any help would be great to finaly get the Ocam-pi-environment running to start coding for my project.<br>
<br>
Thanks in advance!<br>
<br>
Andreas<br>
