The boot loader will work on both types.<br /> You must have a 1k5 pull up resistor on the USB DP+ line, and 22Ohm in line resistors in the DP+, DP- lines. </p> http://forums.leaflabs.com/topic.php?id=10198#post-22239 Mon, 04 Feb 2013 01:36:24 +0000 kyoji 22239@http://forums.leaflabs.com/ <p>Greetings</p> <p>I was experimenting with MAIPLE mini.<br /> I wrote to the DEVICE Maipleminibootloader of STM32F103CB,<br /> That is USB DEVICE<br /> DVICE is recognized as unknown as "6 &amp; 176E48BB &amp; 0 &amp; 1 USB \ VID_0000 &amp;<br /> PID_0000 \".<br /> I use the DEVICE of STM32F103C8<br /> Be properly recognized "USB \ VID_1EAF &amp; PID_0003 \ LLM_003".<br /> Omit the cutoff 3.3vpullup to deal with USB-HISPEED, I have to remain connected.<br /> Although the same to another substrate using a STM32F103C8,<br /> I recognize correctly.<br /> I will be recognized if you care what the point?</p> <p>Best regards </p>
