Since the blinky program is known to work, that means control never gets to your setup()/loop(). So something before went wrong, and the likely suspect is init(), since the rest of the libmaple startup code is very simple and unlikely to be causing the bug.</p> <p>Not having the right board selected for a single upload is almost definitely <strong>not</strong> the cause of the problem, as you've overwritten the bad first upload every single time you've uploaded another program.</p> <p>Let's try a simple test to see whether or not the USB code in init() is to blame.</p> <p>In the Maple IDE v0.0.12 directory, the source code for init() is in the file hardware/leaflabs/cores/maple/boards.cpp. Open it up; init() is the first function in the file. It looks like this:</p> <pre><code>void init(void) { setupFlash(); setupClocks(); setupNVIC(); systick_init(SYSTICK_RELOAD_VAL); gpio_init_all(); afio_init(); setupADC(); setupTimers(); setupUSB(); boardInit(); }</code></pre> <p>Here are the steps to follow to test things out:</p> <ol> <li>Close Maple IDE if you have it open.</li> <li>In init(), comment out the line that says <code>setupUSB();</code> and save boards.cpp. (It's the second-to-last line in the function.) </li> <li>Reopen Maple IDE, and recompile/upload the blinky sketch to the Maple Mini. </li> <li>Reset the board a few times. </li> </ol> <p>If there is something wrong with the way USB enumeration is working, then the board should blink every time you reset. Does that happen?</p> <p><strong>IMPORTANT: though the board should blink, the /dev/ttyACM will not come up, since you commented out setupUSB(). Make sure to uncomment setupUSB() after you're done with the test, so things work normally afterwards.</strong> </p> http://forums.leaflabs.com/topic.php?id=2185#post-11945 Mon, 23 Jul 2012 16:13:59 +0000 aliosha 11945@http://forums.leaflabs.com/ <p>i'm using maple ide 0.0.12 on ubuntu 32 bit and the libmaple that came with it. </p> <p>so the blink sketch is the example provided with the ide. nothing changed...</p> <p>but if init() is crashing, why every 2nd time? because on every second reset it works well, I have developed a lot of code on it. see: <a href="https://github.com/everycook/EveryCook_Firmware" rel="nofollow">https://github.com/everycook/EveryCook_Firmware</a></p> <p>but now the firmware is ready and for the integration in my machine the reset problem is really annoying :-(</p> <p>I remember that at my very first upload I had the wrong board selected. may that be a reason? see: <a href="http://forums.leaflabs.com/topic.php?id=1215" rel="nofollow">http://forums.leaflabs.com/topic.php?id=1215</a></p> <p>I can't remember how the board worked before that... </p>
