I have a windows app that sends the following 8 bytes to the NXP
LPC2478 UART2 at 38400, 8 bits 1 stop. 

 
01 06 02 00 01 03 09 9B 

 
Once received the NXP echos these bytes back to PC. 

 
What I get back is 01 06 02 00 01 03 09, the 9B is missing</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: UART Tx issues</title><link>https://community.arm.com/thread/77075?ContentTypeID=1</link><pubDate>Fri, 16 Jan 2009 12:51:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:2f9f4ab5-0a20-465c-85d5-01cbf57c11d6</guid><dc:creator>Lester Panek</dc:creator><description>&lt;p&gt;&lt;p&gt;
I verified using the ULink2 that the NXP did in fact receive the
characters properly. Also when I send the charactes I see that all 8
are being sent. A call is made to this function to send all 8
characters&lt;/p&gt;

&lt;p&gt;
int com_putchar (int ch) { while (!(*UxLSR &amp;amp; 0x20)); *UxTHR =
ch;&lt;/p&gt;

&lt;p&gt;
return (*UxTHR);&lt;br /&gt;
}&lt;/p&gt;

&lt;p&gt;
On the PC side I have a serial monitoring program which I have
used for a number of years to monitor what the PC is receiving.&lt;/p&gt;

Obvious place to start:&lt;/p&gt;

&lt;p&gt;
1. does the NXP receveive the bytes correctly?&lt;/p&gt;

&lt;p&gt;
2. does the NXP &lt;i&gt;think&lt;/i&gt; that it&amp;#39;s sent the &amp;quot;echo&amp;quot; bytes
correctly?&lt;/p&gt;

&lt;p&gt;
Does it work in the simulator?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
