The java expects a reply of the form "Found DFU: [0x...." The new version does not have the 0x prefix -- so it won't work with the MAC version of Maple IDE.

When you hold the BUT button down and then hit reset you enter the serial bootloader mode. You can use this to upload a new bootloader, or just code you generated outside of the ide (perhaps still using our libmaple library...). Were really pleased about how well this serial bootloader mode works, armed with only an FTDI chip or an arduino, or some means of getting board level (3.3 or 5v should work) serial out from your PC you can do away completely with our IDE and bootloader and hack on as low as level as you want! </p> http://forums.leaflabs.com/topic.php?id=76#post-451 Fri, 02 Jul 2010 08:42:30 +0000 wyzarddoc 451@http://forums.leaflabs.com/ <p>poslathian;<br /> Rest easy I am happy and it's working so I am off to seeing what I can do with the board.

Perhaps you were missing the hold part? Also, it sounds like youre up and running now?..! If thats the case, then awesome, I will rest easy. Otherwise let us know! </p> http://forums.leaflabs.com/topic.php?id=76#post-426 Wed, 30 Jun 2010 15:38:28 +0000 wyzarddoc 426@http://forums.leaflabs.com/ <p>Hi bnewbold;<br /> Maybe you need to label the but with "if all else fails press here" LOL. When I plug in the usb cable the program/sketch? starts running. If I press the reset button I get 6 fast flashes during which I hit the but button I get a brief period of no led activity then a few seconds later the led starts running the program/sketch again. Unit accepts new programming over usb and loads just fine. If I hold the but button down and then press the reset button the led goes out completely until I hit the reset button again which restarts the program/sketch. I'll try your pin 38 test in the next couple of days<br /> thanks<br /> Doc </p> http://forums.leaflabs.com/topic.php?id=76#post-420 Wed, 30 Jun 2010 02:08:22 +0000 bnewbold 420@http://forums.leaflabs.com/ <p>Hey wyzarddoc!</p> <p>If I understand correctly you got the automatic reset through the IDE working (so you can upload programs) but you aren't sure if the "BUT" button works to get you in perpetual bootloader mode? If Reset-while-BUT turns off the LED that means the micro is successfully in hardware bootloader mode*. The Reset-then-BUT-quickly combination (press and release Reset then very quickly hold BUT right when the LED starts blinking quickly for several seconds, which will result in the LED blinking continuously) is kind of tricky, though it is possible that the BUT is only half-working. You can double-check the later half of the functionality by writing a quick sketch puts pin 38 (the BUT button) into INPUT_PULLDOWN mode, then constantly updates the LED (pin 13 in OUTPUT mode) with the digitalRead of BUT; with this sketch running the LED should turn on/off (or off/on?) when you hold BUT down.</p> <p>*: Maybe we should come up with better names like "Swiss engineering FTW" mode and "oh please oh please last resort" mode? ;) </p> http://forums.leaflabs.com/topic.php?id=76#post-419 Wed, 30 Jun 2010 00:45:46 +0000 wyzarddoc 419@http://forums.leaflabs.com/ <p>Well kinda figured out the problem. I plugged in the Maple with my device manager open as soon as I saw the yellow caution USB I clicked on it and then had it load the serial port. Seems to be working now with usb/serial reset. I still question if the Reset/But is working don't see a change when I hit the but after a reset during the 6 quick blinks but have found that hitting the reset with the but button pressed turns off the led<br /> ??<br /> thanks<br /> Doc </p> http://forums.leaflabs.com/topic.php?id=76#post-417 Tue, 29 Jun 2010 23:02:16 +0000 wyzarddoc 417@http://forums.leaflabs.com/ <p>Hi All;<br /> I am getting the same error while trying to communicate with my maple. Couldn't find the DFU device: [1EAF:0003]. When I try the the Reset/boot I don't see a change in the blink rate etc. Also when I plugged the board into windows I did not get a driver request. I have been successful programming Arduino's with this machine. Any help will be appreciated.thanks<br /> Doc </p>
