Hello, For a while now, I have been looking at the option of using the AT91SAM with the ethernet option. To do so, I have had to glue a chip which can now be hooked onto the actual ethernet socket/ cable. I could not find the DM9161 or something which has a driver for the AT91SAM, but instead I am using the 8201 which is also 10/100. While I had to put in enough time to wire the chip to AT...

Have built 650 units using the AT91SAM7S256AU Rev A chip. Next build used Rev B chip Ocaisoinal problems are encountered with starting the processor from power up. The application is running under Keil RTX. No changes make to code between Rev A and Rev B build. Using the JTAG to investigate shows the processor to be hung initializing the RTX. The main function is called which calls the os_sys...

Hi all, I am trying to load linux from dataflash and having some problem. I put bootstrap at address 0x0 U-Boot at address 0x8400. U-Boot was compiled for dataflash, but when I power-up the board I get the follow messages: *U-Boot 1.2.0 (Sep 13 2008 - 17:32:34) U-Boot code: 23F00000 -> 23F28E6C BSS: -> 23F87D14 DRAM: 64 MB NAND: No NAND device found!!! No NAND device found!

I have a sam9-l9260 board from olimex.I want to use dataflash to store bootstrap and u-boot.I have used the bootstrap provided my olimex to compile the bootstrap for dataflash.I have set the preprocessor CFG_ENV_IS_IN_DATAFLASH to 1 and compiled u-boot provided by olimex. I have fused dataflash with the bootstrap at 0x0000 in dataflash and u- boot at address 0x8400 .As soon as I reset th...

Hi all, I wonder what is the NAND flash you use in a design with an at91sam7s parts ? Size, brand etc... We are looking to put 1 Nand on our design but this is the first time we do this. We have always put dataflash and not nand. Regards jonathan ------------------------------------

Hi all, I have a bootloader which is located at flash memory 0x0000 to 0x4000 and ram memory 0x0000 to 0x2000. The bootloader itself has enabled the remap feature. Now, I wish to write my application in IAR but I have no idea on how to write my linker setting (*.xcl). Here is my non-working example. Any expert who can hint what was wrong? All kind of hints will be greatly appreciated. //****...

I am working with the AT91SAM7SE512 chip on a custom built board. I was trying to erase the flash and enter in the bootloader SAM-BA, but I couldn't get the chip to enumerate. I checked the documentation for this chip and I realized that the USB requirement is an 18.432 MHz Quartz crystal. The board we designed is using a 20.0 MHz crystal. Is there a way to get this 20.0 MHz crystal runni...

Hi all, I have the exact same problem as described here by Cliff. http://www.embeddedrelated.com/groups/AT91SAM/show/2053.php However, my bulk in endpoint is set up for bulk(b0010) not iso. Does anyone else have any ideas or tips to give me in debugging this problem? I have usbsniffers and can view my bulk out endpoint working correctly. When i transmit a character out of the hy...

Hi guys, I hope you can help. I am getting desperate! I am having the exact same problem you describe here - except my IN endpoint is not iso but set to bulk. Do you know of any other reasons why I may be getting the exact same issue? Why should the bulk-in endpoint lock up after one transmission and my bulk-out endpoint remains functioning correctly? Also, does anyone thing using usbser....
