at91rm9200 sd card performance

Started by tesla February 14, 2006
Hello,
I have couple of questions in my head before buying an ev board..

Does anybody knows  at91rm9200 sd card read/write performance?

Does AT91rm9200 uses 4 wire sd mode or only 1 wire spi mode?

what is maximum sd card erad/write performance when programming in
assembly and C ?

What is maximum performance of uclinux sd card drivers?
(Are sd drivers from uclinux or uboot?)

Thanks

You can download the EV board manual from the Atmel website, it includes the schematics so you can see for your self. -- Stef (remove caps, dashes and .invalid from e-mail address to reply by mail) America is the country where you buy a lifetime supply of aspirin for one dollar, and use it up in two weeks.

Really? What would you say about Danish Imams who actually ignited all this rage, *three and a half months* after the original cartoons have appeared in the press? http://bibelen.blogspot.com/2006/01/imams-showed-pedophile-mohamed.html Need some more facts? Here we go, the fresh look from Egypt: "Now while the arab islamic population was going crazy over the outrage created by their government's media over these cartoons, their governments was benifitting from its people's distraction. The Saudi royal Family used it to distract its people from the outrage over the Hajj stampede. The Jordanian government used it to distract its people from their new minimum wage law demanded by their labor unions. The Syrian Government used it to create secterian division in Lebanon and change the focus on the Harriri murder. And, finally, the Egyptian government is using it to distract us while it passes through the new Judiciary reforms and Social Security Bill- which will cut over $300 million dollars in benefits to some of Egypt's poorest families." http://egyptiansandmonkey.blogspot.com/2006/02/boycott-egypt.html Major off-topic. Sorry, couldn't resist.

Indeed you did't say that. But in fact you failed to mention at all which EV board you plan to use so I assumed (wrongly, I'm so very sorry but my crystal ball has failed me again) that you where talking about the Atmel one. I did see the schematics in the manual and hoped that those could help you out. Wrong again, dammned crystal ball.

Another piece of information you did not mention in your first post.
>Are you from nl?
I'm not sure what that has to do with this, but yes.

What the hell did you smoke?
