Hello! 
I&amp;#39;m developing an application which requires the heap to be located
in a 32MB off-chip SDRAM. I&amp;#39;m using Keil RTX in the project. The
problem is the application falls when a function malloc() is
calling. 

 
The crystall used is STM32F746IG </description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Allocate HEAP into external SDRAM with Keil-RTX</title><link>https://community.arm.com/thread/84956?ContentTypeID=1</link><pubDate>Mon, 23 Jan 2017 02:49:50 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:020d0b2d-a0ee-42c9-bba7-8a94c378367b</guid><dc:creator>Paul Krechka</dc:creator><description>&lt;p&gt;&lt;p&gt;
Hi there, i&amp;#39;ve faced with th same problem.&lt;br /&gt;
Did you solve them?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Allocate HEAP into external SDRAM with Keil-RTX</title><link>https://community.arm.com/thread/82925?ContentTypeID=1</link><pubDate>Tue, 24 Nov 2015 04:11:24 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:cd8964e4-68c0-458a-a2cb-b79350e4d213</guid><dc:creator>George Belyakov</dc:creator><description>&lt;p&gt;&lt;p&gt;
Yes, i tried write/read data at full range of memory, and it works
correctly. I made a full test with write-read operations using
pointers for each address in [0xC0000000 to 0x02000000] range.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Allocate HEAP into external SDRAM with Keil-RTX</title><link>https://community.arm.com/thread/69423?ContentTypeID=1</link><pubDate>Tue, 24 Nov 2015 00:38:06 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:6cc5126c-c530-4c13-be39-e3bc7d5f2e38</guid><dc:creator>edPer Westermark</dc:creator><description>&lt;p&gt;&lt;p&gt;
And before worrying about function of malloc() - have you tried if
your own code can correctly read and write to the external RAM?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
