Hi all, 

 
I am testing a application in TMS470R1B1M evaluation baord with
ULINK2 as debugger and Environment is uVision3.Compiler selected is
RealView ARM. 

 
As per TI TMS470 Data sheet,some of the pheripheral registers can
be written only in privilege</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Writting  to TMS470's pheripheral registers</title><link>https://community.arm.com/thread/48105?ContentTypeID=1</link><pubDate>Fri, 04 May 2007 06:47:39 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:5504df20-e13d-4d1e-83e0-5a0660378d61</guid><dc:creator>PRAVIN T</dc:creator><description>&lt;p&gt;&lt;p&gt;
I commented the code for jumping to User mode in startup code of
TMS470 so that CPU is always in supervisor mode.Now I am able to
update all the SFRs.&lt;br /&gt;
Is there any thing harm in running the total application in
&amp;quot;Supervisor mode&amp;quot;,since I may want to update the SFRs during run
time.&lt;/p&gt;

&lt;p&gt;
regards&lt;br /&gt;
PRAVIN T&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
