Hello, 

 
I try to setup a SW environment for a Board with a NXP LPC2468 and
an external static memory Chip, using uVision4 and the Keil RTX. I
want to use the external RAM as standard Heap (not for program
execution). The EMC Controller should be</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Use external static RAM as heap with uVision and RTX</title><link>https://community.arm.com/thread/106812?ContentTypeID=1</link><pubDate>Mon, 04 Feb 2013 22:34:04 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:a433d001-0f9e-47b2-9278-c198a4903e43</guid><dc:creator>Dejan Durdenic</dc:creator><description>&lt;p&gt;&lt;p&gt;
Yes, that should be enough. You also have to tell linker where
that RAM is located (Project Options -&amp;gt; Target -&amp;gt; Read/write
memory areas), so your project can be linked accordingly.&lt;/p&gt;

&lt;p&gt;

I have configured the EMC within the startup file, using the
uVision configuration wizzard. Is that the correct position to do, or
do I have to setup an extra initialization file?&lt;/p&gt;

&lt;p&gt;

You have to initialize external memory interface - as soon as
possible after reset - in the startup.s (or whatever thg name is)
file. Otherwise, C environment intialization routines, which are
called BEFORE your main() code won&amp;#39;t be able to access external RAM.
I hope this helps.&lt;/p&gt;

&lt;p&gt;
