While the led is flashing fast, I still didn't see any usb device by 'lsusb'.<br /> Maybe I need a check and a rework on the borad hardware? </p> http://forums.leaflabs.com/topic.php?id=1039#post-6669 Thu, 29 Sep 2011 12:36:20 +0000 mbolivar 6669@http://forums.leaflabs.com/ <p>have you ported the bootloader to work on your new board? does it have the same USB DISC pin as maple?</p> <p>if the answer to either of those questions is yes, then things should work, and the board should come up as a DFU device. if the answer to both of those questions is no, then you'll need to port the bootloader to your board. </p> http://forums.leaflabs.com/topic.php?id=1039#post-6667 Wed, 28 Sep 2011 19:51:53 +0000 librae8226 6667@http://forums.leaflabs.com/ <p>I am considering that maple bootloader do "setupUSB()" while initializing, so it can be recongnized when even running bootloader only.<br /> Right? </p> http://forums.leaflabs.com/topic.php?id=1039#post-6666 Wed, 28 Sep 2011 19:49:45 +0000 librae8226 6666@http://forums.leaflabs.com/ <p>Hey poslathian,</p> <p>Here comes another question about the USB.<br /> I am trying to use a non-maple board for now.</p> <p>Should it be listed out as a USB device on host PC after downloading &amp; running maple bootloader?</p> <p>Is there any hardware related issues?<br /> Because I don't have a BUT and a BOOT0 pull down connection, just a jumper to choose 1 or 0 for BOOT0.<br /> Can I make it recongnized by PC USB with or without some rework with hardware?</p> <p>Many Thanks.<br /> Librae </p> http://forums.leaflabs.com/topic.php?id=1039#post-6614 Mon, 26 Sep 2011 08:32:54 +0000 poslathian 6614@http://forums.leaflabs.com/ <p>thanks! </p> http://forums.leaflabs.com/topic.php?id=1039#post-6606 Mon, 26 Sep 2011 04:16:38 +0000 librae8226 6606@http://forums.leaflabs.com/ <p>Hi poslathian,</p> <p>Many thanks for your attention.<br /> Yes, I heat it and it is all ok now.</p> <p>I am considering that nobody would come because it is a so low-class problem caused by myself.<br /> I might hit it on somewhere...</p> <p>Maple board is very nice actually :P<br /> Keep going on! </p> http://forums.leaflabs.com/topic.php?id=1039#post-6420 Tue, 20 Sep 2011 12:12:30 +0000 poslathian 6420@http://forums.leaflabs.com/ <p>wow...</p> <p>sorry you were having trouble. but you say you are all set now? was the USB port just not 100% on and so heating it improved the joint? </p> http://forums.leaflabs.com/topic.php?id=1039#post-6360 Thu, 15 Sep 2011 12:49:57 +0000 librae8226 6360@http://forums.leaflabs.com/ <p>OMG!<br /> Fix it.<br /> It's about the hardware.<br /> I heat the miniusb and those two resistances around it use soldering iron and everything is ok now. </p> http://forums.leaflabs.com/topic.php?id=1039#post-6352 Wed, 14 Sep 2011 23:12:53 +0000 librae8226 6352@http://forums.leaflabs.com/ <p>I think in the bootloader, maple will talk to host pc, so usb device cannot be nothing with the board.<br /> There should list a usb device called as leaf:0004 or something.</p> <p>According to above, the problem seems to be on the hardware...</p> <p>But I've measured the usb cable with the chip, nothing seems wrong - -!</p> <p>Any ideas? </p> http://forums.leaflabs.com/topic.php?id=1039#post-6351 Wed, 14 Sep 2011 22:44:51 +0000 librae8226 6351@http://forums.leaflabs.com/ <p>Hi leaflabs,</p> <p> I think my problem is clear:<br /> Reflashed the maple_boot.bin built from "maple-bootloader.git", no user code in flash.</p> <p> My situation is:<br /> While using IDE, it came a message "Couldn't find the DFU device: [1EAF:0003]".<br /> While using libmaple in command line, typein "dfu-util -a1 -d 1EAF:0003 -D build/maple.bin -R", it came a message "No DFU capable USB device found".<br /> While typein "dfu-util -l", there would be the situation same as unplugging maple usb cable.</p> <p> The most strange thing is that there was no usb device listed out (typed in "lsusb") for corresponding maple board while the borad running looks correct(fast flash then slower).</p> <p> I've tried methods mentioned in forum, program it directly without recognizing serial device.<br /> <a href="http://forums.leaflabs.com/topic.php?id=178" rel="nofollow">http://forums.leaflabs.com/topic.php?id=178</a><br /> And checked the docs for 0.0.12<br /> <a href="https://github.com/leaflabs/leaflabs-docs/commit/20567605e2cc6a0414177b87efc7ab9b495898e2" rel="nofollow">https://github.com/leaflabs/leaflabs-docs/commit/20567605e2cc6a0414177b87efc7ab9b495898e2</a></p> <p> Still doesn't work.<br /> So, I have to turn to you excellent guys :P</p> <p> My environment:<br /> Board: maple r5<br /> Host OS: Fedora 15 &amp; Ubuntu 11.04 &amp; Windows XP</p> <p> Ps: Before I reflash the bootloader, it worked well on each environment.</p> <p>Thanks,<br /> Librae </p>
