A safer workaround for now would be to comment out the call to disableDebugPorts() in Maple Mini's boardInit(). </p> http://forums.leaflabs.com/topic.php?id=843#post-5059 Wed, 08 Jun 2011 13:42:00 +0000 gbulmer 5059@http://forums.leaflabs.com/ <p>ianmga - the 48pin STM32F103CB has all the JTAG signals on the headers.</p> <p>I looked at the datasheet at:<br /> <a href="http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00161566.pdf" rel="nofollow">http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD00161566.pdf</a></p> <p>and JTAG is on:<br /> <pre><code>Name Port Mini-pin JTMS PA14 D21 JTDI PA15 D20 JTDO PB3 D19 JNTRST PB4 D18 NRST NRST RESET</code></pre> <p>You'll need to make an adapter of some description.<br /> Several people have used dorkbotpdx.org for one-off (three off) PCBs, but you could use veroboard.</p> <p>(full disclosure: I am not a member of LeafLabs staff) </p> http://forums.leaflabs.com/topic.php?id=843#post-5055 Wed, 08 Jun 2011 11:45:23 +0000 ianmga 5055@http://forums.leaflabs.com/ <p>Uuuhh. Is there a way to JTAG your way into the Mini? I was checking out the wonders of the Mini I just got and realized I had assumed it had a JTAG connector somewhere. </p>
