OE is a fascinating topic, and I'm happy to help others learn it. Chris Thank you both. OE is a fascinating topic, and I’m happy to help others learn it.

Partly because so many people have documented things they only partly understand. These guides have helped me a great deal, so thanks.

Glad this article set helps in some fashion. To start searching for the answer to your question, I'd recommend going back to the source. Atmel has a lot of great information on the AT91SAM9261 CPU on <a href="http://www.atmel.com/dyn/products/product_card.asp?part_id=3638" rel="nofollow">their website</a>. The datasheet for the CPU (sometimes called "Preliminaries") should indicate whether booting from nandflash is supported. A quick Google search using "at91sam9261 boot nandflash" revealed <a href="http://www.at91.com/samphpbb/viewtopic.php?p=8606" rel="nofollow">an answer</a>. User <em>ivunin</em> indicates that on page 83 of the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6062.pdf" rel="nofollow">AT91SAM9261 preliminary</a>, Atmel specifically mentions that booting from nandflash is not supported. It looks like dataflash must be used to boot, and then nandflash can be used for partitions like <code>/usr</code> or similar. Best of luck, Chris Hi Sasho,

It took me 3 weeks to set my board up... If only these 3 articles were available at the time, ahhhh... :) Now a noob question: I have another board based on at91sam9261 and there is very little information on it (unless u speak Chinese, and I don't). Is there any way I can find out whether it's dataflash or nand based? Is it safe to experiment with data/nand images on it to find out? Great job!
