But any how to get AT91SAM7S64 on it?

And if you really want that SAM7S64 part, you can replace what's on the EVB. It has dual footprint for the MCU.

I think the amount of FLASH and RAM are the only differences, as the 256 has more than the 64 then there should not be a problem. You can use either.

The LQFP48 is only required for the '32 all others are LQFP64. You need to remove the existing CPU anyway, as the LQFP48 is under the LQFP64.

But if you really can only use the '64 (I really can't understand why though), buying that separately and replacing it is a good option.

Thanks for input.

I was just trying to stick to tutorial specifications. Anyway, I'll give it a try.

thanks, ali

Folks thanks for input. And I hope x256 will be ok. But, any thoughts for tutorial ? I can't see even a single comment there (Embedded.com) although It was uploaded on 06/26/07.

When is the next article supposed to come out? I don't want to rain on your parade, but it has been four months since the first article and I couldn't find any sign of the second one.

I just got started in the ARM7 world myself. I bought an Olimex board from

(a way cool place), a JTAG module, and dove in. I was going to get a SAM7, but switched to the NXP at the last minute because the Atmel board was out of stock. After digging thru both manufacturers' documentation, I think I like the NXP a bit better anyway.

There's a fairly good tutorial by a fellow named James Lynch. It's called "ARM Cross Development with Eclipse". It shows how to put together a working toolchain for cross compiling.

fromwww.sparkfun.com(a way cool place), a JTAG module, and dove in. I was

Search embedded.com for 'Building Bare-Metal ARM Systems with GNU' you will see '10' part tutorial there. Yeah , NXP is fine but just wan tto stick to atmel;-)

I read all of it and thought it was very good. Especially useful if you are thinking about experimenting with c++ - I have not seen this covered before.

The actual code is labelled "all rights reserved". I am not sure what that is supposed to mean in practice but I guess you can't use it as-is for the basis of your own projects. But the insight gained should still be worthwhile.

The FreeRTOS.org site also has some information on using Eclipse/GCC/ARM:

[just working on one for the SAM7 too]

Using Eclipse with the FreeRTOS.org demos:

Note that these direct links won't show you the menu frame. To see the menu frame go directly to the homepage.

Yes John, I must agree with you. It is indeed kinda unique and article concentrates on over all system rather just a single thing. I can see people recommending another tutorial which is using AMR7 from NXP , but IMHO that tutorial is merely for configuring the toolchain and thats it. It does not talk about such details that are covered in Miro Samek's article.

Maybe no one has tried that and thats why there are no comments. Or maybe no worth to comment;-)

What is the difference between AT91SAM7S-EK IAR and AT91SAM7S-EK RSV?

thanks, ali

Ok, IAR means board shipped with IDE from IAR company and J-LINK ICE interface with its A/B type USB cable.

But no Idea what comes with RSV version!
