I believe that insures that the characters are sent out before the close. </p> http://forums.leaflabs.com/topic.php?id=2451#post-12508 Fri, 17 Aug 2012 14:28:45 +0000 Anonymous 12508@http://forums.leaflabs.com/ <p>Awesome, thanks! I was running into the same issue periodically and this helped. </p> <p>I still have issues with the IDE reset only working half the time. I wonder if there is a fix for the IDE that is similar. </p> http://forums.leaflabs.com/topic.php?id=2451#post-12501 Fri, 17 Aug 2012 10:26:15 +0000 Anonymous 12501@http://forums.leaflabs.com/ <p>I don't know what was causing the problem, but I have managed to get it to reset it over serial.

If I use the IDE, I don't have to reset the board every time. If I connect to the board with the IDE serial it will allow me to upload to the board again. I am able to connect serially to the board, but I can not reset it from serial.</p> <p>I have the rev 3+. </p> http://forums.leaflabs.com/topic.php?id=2451#post-12493 Fri, 17 Aug 2012 06:19:10 +0000 asterix 12493@http://forums.leaflabs.com/ <p>Sorry, just read it works in the IDE :/ . You can also manually hit the reset button to force an upload. </p> http://forums.leaflabs.com/topic.php?id=2451#post-12492 Fri, 17 Aug 2012 06:18:03 +0000 asterix 12492@http://forums.leaflabs.com/ <p>I've sometimes run into this problem in various situations. More so when powering external devices off maple mini's vcc or if there are other peripherals attached to GPIO pins. If you've got an external source plugged in, remove the ViN connection before attaching the usb cable. </p> http://forums.leaflabs.com/topic.php?id=2451#post-12479 Thu, 16 Aug 2012 23:25:41 +0000 Anonymous 12479@http://forums.leaflabs.com/ <p>I'm on Mac OS Mountain Lion and I have to put the board into perpetual bootloader mode every time I want to upload a new build.
