I use MCBTR9 Board, the serial interface works in the ordinary
system, but if the system is integrated with task(RTX), then it does
not work. 
could you please advise me, what i do.

why do you think Ms. embedded likes me so much ;-)&lt;br /&gt;
where are you girl!&lt;/p&gt;

Whoops - Tamir is a faster typist than me!&lt;/p&gt;

Have you tried the &amp;#39;U&amp;#39; test by continuously transmitting a &amp;#39;U&amp;#39; and
scoping for a correct waveform?&lt;/p&gt;

&lt;p&gt;
When I did the same thing as you, it gave me the opportunity to
better understand the clock options in STR912. There are a lot of
setting that need to be right. I found I was transitting &amp;#39;U&amp;#39; but at
the wrong speed!&lt;/p&gt;

&lt;p&gt;
I found that the simulator was particularly good for this to check
the baud and other values.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: RTX UART0 STR912FW44</title><link>https://community.arm.com/thread/100983?ContentTypeID=1</link><pubDate>Tue, 19 Aug 2008 04:26:13 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:08e61180-b259-4da5-8b68-8d7d1423c9dc</guid><dc:creator>Catcus Blip</dc:creator><description>&lt;p&gt;&lt;p&gt;
* verify connection settings (baudrate, stop bits...)&lt;br /&gt;
* test TX line with scope to verify no signal&lt;br /&gt;
* can you run your application in the simulator?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: RTX UART0 STR912FW44</title><link>https://community.arm.com/thread/76584?ContentTypeID=1</link><pubDate>Tue, 19 Aug 2008 04:00:35 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:6c06ac3e-a7fc-40b7-ba33-ea4a57705c32</guid><dc:creator>Amer Boudaoud</dc:creator><description>&lt;p&gt;&lt;p&gt;
yes i initialized the UART0.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: RTX UART0 STR912FW44</title><link>https://community.arm.com/thread/52234?ContentTypeID=1</link><pubDate>Tue, 19 Aug 2008 03:43:20 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:170ddf78-550c-4d9a-8c29-9861c9383475</guid><dc:creator>Catcus Blip</dc:creator><description>&lt;p&gt;&lt;p&gt;
I suppose your example code for the UART of the MCBSTR9 works.
have you remembered to initialize your UART before any task attempts
to use it?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
