When I first started the IDE I had typed in an empty program just to see if it would compile and upload. I had selected to upload to RAM for this. Then I switched to Flash and started trying to upload real programs. I guess RAM takes precedence over Flash. I had reset the board a few times but never removed power. Once I removed power, the RAM was cleared and the Flash programs started working. I just ran this sequence of events again and it does appear that RAM takes precedence, and that a simple reset does not clear the RAM program.</p> <p>So, it's all good now. Thanks! </p> http://forums.leaflabs.com/topic.php?id=546#post-2918 Wed, 01 Dec 2010 19:41:38 +0000 poslathian 2918@http://forums.leaflabs.com/ <p>Hmm. That is odd. Can you check and see if there is any difference when you have the serial monitor open or closed? </p> http://forums.leaflabs.com/topic.php?id=546#post-2915 Wed, 01 Dec 2010 19:00:33 +0000 vonnieda 2915@http://forums.leaflabs.com/ <p>Well, now it's all working fine. No idea what happened. Thanks anyway! </p> http://forums.leaflabs.com/topic.php?id=546#post-2914 Wed, 01 Dec 2010 17:24:47 +0000 vonnieda 2914@http://forums.leaflabs.com/ <p>Hi all, I just got my Maple r5 in the mail and decided to try a few of the examples. So far I'm not getting any love. I've tried Blink and Hello World. Upload seems to work fine but Blink doesn't Blink and Hello World doesn't emit anything to the serial port. </p> <p>Here's the output from uploading the Blink example. Code is unchanged from the shipping IDE.
