Hi everyone, 

 
Please, I&amp;#39;m using the examples given with the keil solution to
implement a program that uses the DMA between the UART and a buffer,
the problem is that I want the DMA to interrupt when the buffer gets
full, but then to restart working</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Reinitialize the DMA</title><link>https://community.arm.com/thread/55985?ContentTypeID=1</link><pubDate>Tue, 05 May 2009 15:43:45 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b1108345-60b0-487d-9434-7aea46b128ec</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
If you read your post again - do you really think that you
supplied enough information for people to be able to help you?&lt;/p&gt;

&lt;p&gt;
You have not posted any source code for your DMA usage.&lt;br /&gt;
You have not supplied the name of the processor.&lt;br /&gt;
You have not supplied any information what you have done to try and
loate the problem.&lt;br /&gt;
You have not mentioned if you run double-buffered, or if you only
have one buffer, in which case the transfer will be stopped until you
service the interrupt.&lt;br /&gt;
You have not mentioned if you use DMA for memory-to-memory, or from
device-to-memory or if it is device-fifo to device-fifo or some other
combination.&lt;br /&gt;
You have not told if you do large DMA transfers, or if the restarted
DMA transfer may end before the first interrupt ends.&lt;br /&gt;
...&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
