Hi everyone, 

 
I&amp;#39;m new in the world of arm and microcontrollers, and I&amp;#39;m facing a
weird problem. I&amp;#39;ve uploaded my 
code into the flash memory, and it works just fine. But when I
disconnect the UART utilized to burn it, 
the program stops running.</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Problem running codes on LPC2148</title><link>https://community.arm.com/thread/131405?ContentTypeID=1</link><pubDate>Mon, 12 May 2014 09:59:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:d2847535-b8b3-43b1-8256-aaf1b2448e11</guid><dc:creator>Rodrigo Ara&amp;#250;jo</dc:creator><description>&lt;p&gt;&lt;p&gt;
Using a push button. The code is turn a led on while the push
button is in level 1. But if I disconnect&lt;br /&gt;
the cable, the program doesn&amp;#39;t run normally.&lt;/p&gt;

&lt;i&gt;uart is disconnected, .... I send the command&lt;/i&gt;&lt;br /&gt;
how?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Problem running codes on LPC2148</title><link>https://community.arm.com/thread/117548?ContentTypeID=1</link><pubDate>Sun, 11 May 2014 08:29:12 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:f73624d8-2fd6-4aad-aa8a-8b41e867df45</guid><dc:creator>Rodrigo Ara&amp;#250;jo</dc:creator><description>&lt;p&gt;&lt;p&gt;
But Erik, when the uart is disconnected, the led or lcd wich was
being used in the code, still in high level, but when I send the
command to clear it, it doesn&amp;#39;t works, so I think that ground isn&amp;#39;t
the problem. Do you know anything else that might be ?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Problem running codes on LPC2148</title><link>https://community.arm.com/thread/107671?ContentTypeID=1</link><pubDate>Sat, 10 May 2014 07:47:52 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:03a415ed-e81c-4306-803d-472fe22c6a44</guid><dc:creator>&amp;#178;erik malund</dc:creator><description>&lt;p&gt;&lt;p&gt;
a common issue about &amp;quot;works only when the cable connected&amp;quot; is a
ground missing or &amp;#39;bad&amp;#39; the effect of which does not exist when the
cables ground &amp;#39;takes over&amp;#39;&lt;/p&gt;

&lt;p&gt;

Well, the UART is connected normally, I dont that is a hardware
problem because Im working with a pattern board, I&amp;#39;ve searching about
it and I think that maybe there is a flag in one of the registers,
but I really don&amp;#39;t know. Do you know anything about that ?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Problem running codes on LPC2148</title><link>https://community.arm.com/thread/68668?ContentTypeID=1</link><pubDate>Wed, 07 May 2014 17:06:45 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:45efb76a-fa45-421f-912c-bed4840af538</guid><dc:creator>ImPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
So how did you connect this UART?&lt;/p&gt;

&lt;p&gt;
Does the reset and EINT2 signals go to handshake signals on the
UART, to allow FlashMagic to reset the board and enter the boot
loader? In that case - are these two signals holding a proper signal
level when the UART adapter/cable isn&amp;#39;t connected?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
