Hello, 

 
I&amp;#39;m using the AT91RM9200 controller with a dataflash (connected at
the spi interface). But how could I download some data via the jtag
interface to the spi dataflash? 

 
I could not found any algorithm for the spi interface in the
memory</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: download data via jtag to spi dataflash</title><link>https://community.arm.com/thread/49909?ContentTypeID=1</link><pubDate>Fri, 16 May 2008 12:21:23 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:b8f922ce-91d0-4515-bbe0-fd916a442594</guid><dc:creator>Alan Scott</dc:creator><description>&lt;p&gt;&lt;p&gt;
Hi,&lt;/p&gt;

&lt;p&gt;
first of all the addr for the spi interface is 0xc0000000.&lt;/p&gt;

&lt;p&gt;
You are not able to download code direct to the spi interface
without starting the spi controller. That means you have to write a
small piece of code (maybe it is possible to run this code in the
internal RAM) and after that you could download the code...&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;And if I use the rom-algorithm (under options-for-target -&amp;gt;
target) then...&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
That&amp;#39;s really not your solution!&lt;/p&gt;

&lt;p&gt;
best regards&lt;br /&gt;
Alan&lt;/p&gt;
