These are, for the most part, known issues that are being worked out.</p> <p>One in a while I also experience issues where the Maple doesn't auto-reset for programming and requires manual "incentive." A little pain when developing stuff, but it's easy to get into the habit and not think about it. </p> http://forums.leaflabs.com/topic.php?id=879#post-5411 Sat, 25 Jun 2011 02:17:13 +0000 infyrno917 5411@http://forums.leaflabs.com/ <p>Just got my Maple Rev 5 in two days ago. Played around with the IDE for a while yesterday, just some fun with sending data back and forth through the USB. Worked perfectly for at least 20 or so flashes.</p> <p>Here is my problem: I went to upload some code today and now it hangs while trying to reset over USB after the flash. Not a huge problem there, just hit the on-board reset button and it goes through. But if I open the serial monitor, after sending a single character to the Maple, my IDE will hang indefinitely until I either reset the Maple board or unplug the USB.</p> <p>Running Ubuntu 11.04 x64. Have not changed or updated any software whatsoever. If it was working fine before under the same conditions, why is the board having problems now? </p>
