Hi all, I was wondering if anyone knew anything about the status of Atmel's AT91 support sites at http://www.at91.com and http://linux4sam.org ? They've been down for a couple of days (although the machine they're on is still pingable), and I have a support request that's been outstanding for about the same amount of time. TIA. Steve

Hello experts, For a new project, I am considering the AT91 series of ARM processors from Atmel. Anybody here have experience with these processors, and the tools? I know the "which compiler is best" is a very "religionbased" question, but nevertheless I'll give it a shot. So, in your opinion, which tools is worth a look, and which is NOT? Thanking you in advance. Best regards H...

Hi, i'm working on a AT91SAM7X-EK development board, and i'm trying to figure out if the normal at91 watchdog behavior can be changed or workarounded because: "The Watchdog Mode Register (WDT_MR) can be written only once. Only a processor reset resets it. Writing the WDT_MR register reloads the timer with the newly programmed mode parameters." due to this feature, if i disable watchdo...

I am trying to decide what flavor of the AT91 series ARM ucontrollers to use for a low cost, low volume product. I need 4 channels of 10 bit ADC, and 4 channels of 12 bit DAC (though I could get by with two 10 bit and two 12 bit), hardware PWM would be nice, but I guess I could do it in software. On the one hand, the AT91M55800 sounds attractive with its ADC, DAC (though not enough chann...

Hi there, We are porting a windows application from desktop into embedded Linux on Atmel AT91 ARM Cores, thus we need JTAG to debug the firmware under a Linux environment. However, SAM-ICE only connects via USB to a PC running Microsoft Windows2000 or XP. So I am looking for a JTAG emulator running on Linux. If you have any good idea/knowledge, could you please help? BTW, a frien...

We are looking at using the AT91SAM7S64 in a new project. We had previously tried the ATMEGA32, but it turned out to be underpowered for our needs. The program, however, was less than 100 lines of assembly code for the ATMEGA32. The AT91 does not seem quite as easy to get into as the AVR. I have the AT91SAM7S64-IAR development kit, and am having trouble figuring out where to go next. Most ...

Since I'm doing a port for an architecture using also SPI flash for booting u-boot I need to remove the existing CFG_DATAFLASH configuration which should be portable as the name says but it is hardcoded only for the AT91RM9200DK platform.

Hello, Has anybody already worked with this microcontroller family? Which is your opinion? They seem very interesting because they use an ARM7 core processor and include very useful communications peripherals (ethernet MAC, usb controller, ...) Does anybody know if there are free developing tools: - compiler / linker: i guess that GCC may be useful as this family uses ARM7 cores. - [b...

Hi, Does anyone know of a source for samples of any of the chips in the AT91SAM7 line? My standard net searches show only the dev kits at $250. I don't really want another dev kit, since I already have the full IAR ARM compiler and have done several designs with the AT91R40807. I'd like to put together a small PCB to test the SAM7 series as a replacement for the AT91 controllers in s...

I need to produce an Ethernet-capable embedded device (including TCP/IP stack) for about $50 in low quantities (think perhaps qty 100). I can get a 2-layer board in these quantities for $13, so that leaves only about $40 for everything that goes on the board. The good news is that by far, the dominating resource consumption will be from the TCP/IP stack, and whatever OS overhead there may be...

In my new arm7 design I was biased toward the atmel AT91 seriesbecause I like the AVR chips so much, but after some research and pointers by nice foks such as rickman and Leon, I decided to look toward other manufacturer's offerings. One thing I discovered is that the flash in the atmel chips (which have it) is slow! Thus using a ball grid type package such as the AT91FR40162 with 2Meg of fla...
