Hi, 

 
I facing some problem on P89LPC936 UART portion. After some
debugging, I realized the UART is randomly not working. 

 
Steps I did : 
1. Using UART generated code from Code Architect (To narrow the scope
of the problem) 
2. Under WinXP, testing</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: UART randomly not working !</title><link>https://community.arm.com/thread/51661?ContentTypeID=1</link><pubDate>Mon, 07 Apr 2008 05:23:05 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:4c06ef8a-c0ef-482d-8b85-a1f5ddc63b37</guid><dc:creator>erik  malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
&lt;i&gt;3. Occasionally when MCU power up, UART is not working at
all...(The only way to recover is to power down and power up the MCU
again)&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
does anything else work when this is so?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: UART randomly not working !</title><link>https://community.arm.com/thread/49654?ContentTypeID=1</link><pubDate>Sat, 05 Apr 2008 10:22:45 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:734e62c9-b61a-4789-b183-cb2a59d38744</guid><dc:creator>Catcus Blip</dc:creator><description>&lt;p&gt;&lt;p&gt;
did you actually measure the outputs of the UART to see that it is
not working? maybe it is a windows issue? use a scope, and you will
know!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
