I uploaded blink and now the COM port appears again.</p> <p>I wish this appeared more explicitly somewhere (or maybe I just overlooked it): that you can upload sketches from within the IDE in perpetual bootloader without having to select a COM port.</p> <p>Could someone point me to if this is documented anywhere / document this somewhere if it's not? This would have saved me a good number of hours of digging around forums, docs, and debugging :/ - I realize that this fix maybe would have been obvious to people who have more experience working with microcontrollers than me, but perhaps this should be noted for the fellow noobs. </p> http://forums.leaflabs.com/topic.php?id=6396#post-17372 Thu, 27 Sep 2012 15:30:30 +0000 scott 17372@http://forums.leaflabs.com/ <p>Update: Looks like it's a known issue with the codec shield - <a href="http://forums.openmusiclabs.com/viewtopic.php?f=21&amp;t=289&amp;start=10" rel="nofollow">http://forums.openmusiclabs.com/viewtopic.php?f=21&amp;t=289&amp;start=10</a>, but it seems there is a fix.

New Maple worked right out of the box with a few test uploads of the Blink demo.</p> <p>I should mention, this previous issue with the older maple arose after playing with a MusicLabs Audio Codec shield (<a href="http://www.openmusiclabs.com/projects/codec-shield/)" rel="nofollow">http://www.openmusiclabs.com/projects/codec-shield/)</a>.</p> <p>-- Anyways:</p> <p>Well it happened again when I uploaded a demo codec-shield sketch (to flash, not SRAM): quite literally within 5 minutes of unpacking this new maple (after running those Blink demos) &gt;:/</p> <p>Same exact issue as before. The only notable thing I noticed this time, is that the demo still runs and works on the board. Specifically, the board won't open up a COM port on Windows (see previous thread), but the demo + shield will run A-OK still whenever the board is powered up. </p> <p>I'm a smidge frustrated that I've pretty much spent $120 w/ S&amp;H for these two Maples to have them "bricked"(ish) like this. I'm 99.99% sure this issue isn't due to myself mishandling the boards (the CODEC shield also runs off the board's own 3.3V supply). This has to be either a Maple issue, or a Maple + CODEC-shield issue (everything works a-ok with the Arduinos).</p> <p>I would REALLY appreciate it if any Leaflabs mods/devs have any trouble-shooting ideas (see previous thread for what I attempted already). I'm sitting here left with two bricked boards that appear have the same issue. If any of the devs want, I'd be happy to ship one of the boards off for you guys to play around with.</p> <p>I would file this issue under "Not Cool" and won't risk purchasing another one of these until at least a good explanation for this issue is determined. </p>
