Hello to everyone. 

 
I&amp;#39;am debugging my asm-function. 
I&amp;#39;am using UV3 with ADI Evalution-kit EVAL-ADUC7026QSP. 
Everything works fine when just let it run. 
But when walking step by step (F11) through the programm strange
things occur:

Thanks for posting it, you have saved my live ;-)&lt;/p&gt;

I had the same problem and the following workaround worked for
me.&lt;/p&gt;

&lt;p&gt;
Find and disable the checkbox &lt;b&gt;Enable Instruction Set
Simulation&lt;/b&gt; from the &lt;b&gt;&amp;quot;Options For
Target&amp;quot;-&amp;gt;Debug-&amp;gt;Settings-&amp;gt;Configure RDI Driver-&amp;gt;CPU&lt;/b&gt;
dialog.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Strange error when single-step-debugging</title><link>https://community.arm.com/thread/74462?ContentTypeID=1</link><pubDate>Wed, 18 Oct 2006 06:29:16 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:7297808d-11ae-4210-b36d-d5783f21f543</guid><dc:creator>Dieter Coba</dc:creator><description>&lt;p&gt;&lt;p&gt;
The code is 0x61A00060 =&amp;gt; MOVVS R0,R0,RRX ;if sign has moved to
C rotate through Carry&lt;/p&gt;

&lt;p&gt;
It is a conditionaly executed instruction, only executed when V is
set. RRX is a eXtended Rotation Right through Carry. No idea why the
Single step (F11) gets along.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Strange error when single-step-debugging</title><link>https://community.arm.com/thread/47048?ContentTypeID=1</link><pubDate>Wed, 18 Oct 2006 05:22:10 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:128bd9bf-c51d-465e-acfc-0712a98c4e58</guid><dc:creator>alan raj</dc:creator><description>&lt;p&gt;&lt;p&gt;
Your thinking is appreciated,&lt;br /&gt;
How do you think, is the error?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Strange error when single-step-debugging</title><link>https://community.arm.com/thread/47036?ContentTypeID=1</link><pubDate>Wed, 18 Oct 2006 05:12:56 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:129790c4-c3e4-4114-8b14-bd8067006e0d</guid><dc:creator>alan raj</dc:creator><description>&lt;p&gt;&lt;p&gt;
Just SEE your code again,&lt;/p&gt;
