As you may have read on another thread, we're working on getting 64-bit Linux support into the next Maple IDE. In the meantime, maybe try <code>apt-get install ia32-libs</code> to see if you're crashing on a missing 32-bit shared library load?</p> <blockquote><p> I've tried pointing the serial port at /dev/ttyUSB0 or /dev/ttyS0,</p> </blockquote> <p>These are definitely wrong.

Now the Maple's LED goes dark again after the startup sequence, which is encouraging. But the IDE still crashes on every attempt to upload, same as before. </p> <p>If I designate no serial port, I notice the message "Couldn't find the DFU device: [1EAF:0003]" and if I use lsusb I see 1eaf:0004 as the device.

I've installed the IDE and got it working (using Ubuntu Lucid on AMD64, so I had to download the new librxtxSerial.so and RXTXcomm.jar, and I did that and it seemed fine). Build of the demo program (blink) works fine.</p> <p>I plug the Maple into USB and Ubuntu sees it okay (I use lsusb to make sure). But any attempt to upload the demo crashes the IDE. It compiles and builds, but appears to crash just when it starts to upload. The window disappears too fast for me to see if there's an error message of any kind. I've tried pointing the serial port at /dev/ttyUSB0 or /dev/ttyS0, and loading to Flash or RAM, and the same thing always happens.</p> <p>This may not be relevant, but the first time I plugged in the Maple, its LED went through the startup sequence and then stayed dark. Now, it goes through the startup sequence and keeps blinking (about 4/second, on/off, not "throbbing" I think).</p> <p>Not sure what to try next. Suggestions? </p>
