Is there any alternative way to debug or download code in
stm32M407vgt6 then using usb cable??

There are TWO USB connectors, not clear what specifically the OP
thinks is the &amp;quot;primary&amp;quot; method in this context. The USB for the
STM32F1 ST-LINK, but it&amp;#39;s not &amp;quot;directly&amp;quot; connected to the
STM32F34&lt;/p&gt;

&lt;p&gt;
The USB connected to the STM32F4 part can use DFU mode, either the
one in the System ROM (BOOT[0] strapped high/vdd), or one created as
a user application. The connector can also take a USB Flash drive,
and there is a &amp;quot;Firmware Upgrade&amp;quot; example in the Discovery
firmware.&lt;/p&gt;

&lt;p&gt;
One could connect up USART3, or a CAN transceiver, the real
constraints here are the user&amp;#39;s flexibility to look at other
methods.&lt;/p&gt;

&lt;p&gt;
USART1 (PA9/PA10) is somewhat problematic because of the
VBUS/Capacitor issues.&lt;/p&gt;

&lt;p&gt;
You could connect a different JTAG/SWD pod to the board.&lt;/p&gt;

&lt;p&gt;
Perhaps the OP can be more specific about what exactly the&amp;#39;re
trying to do, and why.&lt;/p&gt;

I don&amp;#39;t really think so because you are using a discovery
board.&lt;/p&gt;

&lt;p&gt;
It does have a STLINK embedded into the discovery board and that
is what the usb is hooked to.&lt;/p&gt;

&lt;p&gt;
Other methods I don&amp;#39;t think are really supported on the board.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Alternative downloading code method in stm32M407vgt6 discovery board</title><link>https://community.arm.com/thread/64052?ContentTypeID=1</link><pubDate>Mon, 31 Aug 2015 06:05:46 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:aa07bd02-4796-4448-bdcc-e154147497a6</guid><dc:creator>Westonsupermare Pier</dc:creator><description>&lt;p&gt;&lt;p&gt;
Well there&amp;#39;s SWD/JTAG, and if you use the boot loader, USART and
CAN.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
