a prototype board. uVision gives me the message: 
 
 &amp;quot;Couldn&amp;#39;t stop the ARM device. Check the JTAG cable&amp;quot; 
 
The particulars: 
 
DBGSEL is pulled low. 
RTCK is pulled low

    Your mentioning of that dll file got me thinking.  Since I have tried everything that I can think of short of sacrificing a chicken, I took a look at that file.&lt;br /&gt;
Like I mentioned, my co-workers installation works fine.  His UL2ARM.dll version is earlier than mine.&lt;br /&gt;
Out of desperation I replaced my UL2ARM.dll (V1.14) with an older one (V1.11).&lt;br /&gt;
It now works great!&lt;br /&gt;
There is a timing problem introduced by this dll, it only seems to affect the secondary JTAG.  Perhaps it is PC dependent, I don&amp;#39;t know.&lt;br /&gt;
An interesting note, version 1.14 DOES work on an IAR kickstart board.  This board has 74x244 buffers inline with the JTAG signals.  I suspect these buffers &amp;quot;correct&amp;quot; the timing enough so it works.&lt;br /&gt;
&lt;br /&gt;
Let me know that you see this, I think it is important.&lt;br /&gt;

the knowledgebase article.  There is also an option that you need to&lt;br /&gt;
&lt;br /&gt;
&lt;pre&gt;
&lt;b&gt;disable &lt;/b&gt; Use Reset at Startup&lt;/pre&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Problems with LPC2106 Secondary JTAG</title><link>https://community.arm.com/thread/112120?ContentTypeID=1</link><pubDate>Thu, 01 Jun 2006 18:45:05 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:d3087fac-8a1a-4e1a-85b7-c485931bfbac</guid><dc:creator>Rich Soennichsen</dc:creator><description>&lt;p&gt;More Information:&lt;br /&gt;
&lt;br /&gt;
I have tried an existing product, using the LPC2106 and 2nd JTAG, on another uVision installation and it works fine.  I used my Ulink.&lt;br /&gt;
&lt;br /&gt;
So it appears the problem is with my software setup.&lt;br /&gt;
&lt;br /&gt;
I have tried, extensively, all debugger settings, always returning to the default.&lt;br /&gt;
&lt;br /&gt;
I can see the target reset when I attempt to connect but then I always get the &amp;quot;Couldn&amp;#39;t stop the ARM......&amp;quot;&lt;br /&gt;
&lt;br /&gt;
Any ideas would be appreciated.  Are there drivers I can replace etc?&lt;br /&gt;
&lt;br /&gt;

It doesn&amp;#39;t work either.&lt;br /&gt;
&lt;br /&gt;
I can still debug fine products that use the LPC2138 and LPC2124 (Primary JTAG).&lt;br /&gt;
&lt;br /&gt;
Tomorrow I will bring in my laptop to try Rowley, perhaps that may rule out hardware issues.&lt;br /&gt;
&lt;br /&gt;

    I added that assembly to startup.s to no avail.  I am at a loss as to what is going on.&lt;br /&gt;
