You can see maple-bootloader branch but i use my own implementation. For download also custom host software. So i not need install DFU driver (and libusb). </p> http://forums.leaflabs.com/topic.php?id=726#post-4255 Sat, 09 Apr 2011 08:05:13 +0000 josheeg 4255@http://forums.leaflabs.com/ <p>This would realy be helpful in the documentation.<br /> or at least in the wiki. </p> http://forums.leaflabs.com/topic.php?id=726#post-4252 Fri, 08 Apr 2011 21:02:14 +0000 gbulmer 4252@http://forums.leaflabs.com/ <p>I used an FTDI USB to 3.3V serial cable:<br /> <a href="http://www.sparkfun.com/products/9717" rel="nofollow">http://www.sparkfun.com/products/9717</a><br /> to program my DIY STM32F board.
