However, for STM32F10xxx, an integrated pull-down is used for JTCK. Having embedded pull-ups and pull-downs removes the need to add external resistors." See page 1031 and 1032.</p> <p>Am I mistaken? </p> http://forums.leaflabs.com/topic.php?id=200#post-2336 Tue, 09 Nov 2010 14:54:56 +0000 mr hanky 2336@http://forums.leaflabs.com/ <p>Can you please tell which of the pins require the pull up?</p> <p>Thanks </p> http://forums.leaflabs.com/topic.php?id=200#post-2235 Sun, 07 Nov 2010 14:25:20 +0000 poslathian 2235@http://forums.leaflabs.com/ <p>you need some pullups on the JTAG lines as well. </p> http://forums.leaflabs.com/topic.php?id=200#post-2136 Sun, 31 Oct 2010 23:00:16 +0000 larryang 2136@http://forums.leaflabs.com/ <p>Is it a simple pin remapping? Or need to put some resistors in or something? I figure a some headers, perfboard and misc. parts are all I need for JTAG? </p> http://forums.leaflabs.com/topic.php?id=200#post-1394 Thu, 23 Sep 2010 15:11:25 +0000 poslathian 1394@http://forums.leaflabs.com/ <p>Theres a less than useful doc here:<br /> <a href="http://leaflabs.com/docs/maple/jtag/" rel="nofollow">http://leaflabs.com/docs/maple/jtag/</a></p> <p>Ill put up a real schematic soon, i dont know wtf that drawing on there is supposed to be. We dont have any plans on selling adapters. Our assumption was that if you were using JTAG you probably had your own rig. </p> <p>Once the new boards (mini, native, oak) come on sale well probably be a lot more likely to add extra accessory style items to the store (jtag, usb, shield kits, etc). </p> http://forums.leaflabs.com/topic.php?id=200#post-1392 Thu, 23 Sep 2010 14:09:19 +0000 rando 1392@http://forums.leaflabs.com/ <p>Sorry posted to wrong area of forum --- Rando </p> http://forums.leaflabs.com/topic.php?id=200#post-1391 Thu, 23 Sep 2010 14:06:14 +0000 rando 1391@http://forums.leaflabs.com/ <p>Folks,</p> <p>I know there are posts on the board re. the connector on the Maple board NOT being compatible with the connector on the JLink-edu. Is there adapter for sale to help with this issue, and if so where do I buy it?</p> <p>Thanks,</p> <p>Randy </p>
