Hello 

 
I m trying to initialise a MT48LC2M32B2 SDRAM coming from MICRON
with a LPC3250. 
Here is my function: 

 
void initSDRAM()
{
 int dummy = dummy;

 SDRAMCLK_CTRL = 0x0; //validation SDRAM HCLK

 MPMCAHBControl0 = 0x1;
 MPMCAHBControl2 = 0x1;</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: LPC3250 and init of SDRAM (MT48LC2M32B2 )</title><link>https://community.arm.com/thread/57380?ContentTypeID=1</link><pubDate>Mon, 10 May 2010 21:52:36 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b2a070d6-fb95-4c57-9e99-251e40fc50d2</guid><dc:creator>jaimy davies</dc:creator><description>&lt;p&gt;&lt;p&gt;
Hi,&lt;/p&gt;

&lt;p&gt;
I am trying to interface similar sdram, MT48LC4M16A2 to LPC3240
and facing same problem. Please let me know if you were able to solve
the problem.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: LPC3250 and init of SDRAM (MT48LC2M32B2 )</title><link>https://community.arm.com/thread/103657?ContentTypeID=1</link><pubDate>Mon, 07 Dec 2009 23:57:09 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:adcdef8d-7de7-4c25-8a5a-4417e8ab8fae</guid><dc:creator>while ();</dc:creator><description>&lt;p&gt;&lt;p&gt;
There is no simple solution to your problem, you have to analyze
datasheet for memory that you are using and implement manufacturers
initialization routine exactly.&lt;br /&gt;
Usually the problem is in delays needed in initialization routine
perhaps they are not as requested by manufacturer.&lt;br /&gt;
Also you can try to find some source code for initializing these
chips and analyze it.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: LPC3250 and init of SDRAM (MT48LC2M32B2 )</title><link>https://community.arm.com/thread/77966?ContentTypeID=1</link><pubDate>Mon, 07 Dec 2009 23:39:54 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:bfefaef8-d9c8-4911-a09a-9d0dc488d81c</guid><dc:creator>Yuga DURNANT</dc:creator><description>&lt;p&gt;&lt;p&gt;
I do. The code I write come from the Phytec example. On the
evaluation board, the code for the initialization SDRAM and my code
for test works great (but it s not the same size and voltage of
SDRAM). When I change the parameters for my SDRAM, there is any
response of it. Therefore I post here.&lt;/p&gt;

&lt;p&gt;
Thanks in advance&lt;br /&gt;

I suggest you take a look at example for Phytec board for
reference, it can be found in folder:&lt;br /&gt;
\ARM\Boards\Phytec\LPC3250\Blinky\&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
