Hello, 

 
I have a lot of errors during programming the AT91SAM9260
(external NOR flash) 

 
e.g. 

 
0x10000000H contents mismatch at (Flash=FFH) (Required=18H)
 

 
I use NCS0 from the controller - if I take a look into the memory
table for the processor</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: contents mismatch</title><link>https://community.arm.com/thread/76038?ContentTypeID=1</link><pubDate>Fri, 29 Feb 2008 06:52:05 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:ba4ae115-394d-4d61-b91c-54ad572aa82a</guid><dc:creator>Juergen Moser</dc:creator><description>&lt;p&gt;&lt;p&gt;
ok I think I found the reason for this behaviour. The data lines
are not able to pull down the voltage to 0V if data are
transmitted.&lt;/p&gt;

&lt;p&gt;
The only IC on the EBI is the flash-IC so the traces are not
long.&lt;/p&gt;

&lt;p&gt;

could it be that there&amp;#39;s no algorithm for this flash memory?&lt;/p&gt;
