Hi, I'm planning to use the Jtag circuit that have been posted here to Flash my AT91SAM7XC256. I do not have a board I will like to make my own. Which Compiler / debuggre / Software simulator are you using for AT91SAM7XC256? By software simulator I mean I do not want to have a phsical connection with the PC and the ARM, I prefer to debug first by software / simulation and when I li...

i'm totally new to this and i need to do my final year project using it. can anyone give any simple example source code and it's appropriate compiler, editor and simulator? i've tried to learn the rowley associates crosswork version 1.7 but i'm still clueless about it n how to use it. please help..really in need ------------------------------------

Hi, I would like to start programming in c++ on a at91sam9260-ek. Is there anyone who can help me with the linker file and startup code for the constructors\destructors(if i need them). What I'm using now is the AT91lib & getting started as an starting point. My compiler are the Yagarto tools. thanks , gene ------------------------------------

I'm using the AT91SAM7X256 on the AT91SAM7x-EK evaluation board. I can run my code on the microcontroller (leds, joystick, uart) and now I try to use interrupts. Has anybody a startup file (in assembler for GNU compiler) for the AT91SAM7x256 with the use of interrupts?? I've made my own crt.s but it is not working, why, I have no idea!

Gentlemen: if you are using embedded Linux, with an AT91SAM7x, then could you share your experience: * Which Linux * Which Tools (Compiler, JTAG interface, debugger...) * Which AT91SAM7S and which config (external DRAM? etc...) * What is the good, the bad etc...

Hi to the list, I've done a little programming on the Atmel AT91SAM7S-EK demo board using the IAR compiler. I've also been working on a board design using the chip and both parallel bus peripherals and SPI peripherals that is coming along nicely. I've been looking for a good text on this processor. Has anyone read any of these books, and have a comment? Or another book? http://...

I've written my own USB bootloader and it is ALMOST working. I'd like to describe my approach and ask for any ideas on what is wrong. First, I'm using IAR C-compiler, my own hardware with an AT81SAM7S256 mpu with USB. All bootloader and USB stack code is located at 3B000 (top 16 k of the 256 flash), and will only allow updating of the lower 240k (more than enough for my application). M...

Hello, I working on project that is based on FreeRTOS for AT91SAM7X256 (Crossworks compiler). I would like to implement following functionality. Let?s assume that because of some system conditions (e.g. number of watchdog system restarts) I would like to decide if software should start FreeRTOS kernel or not. If not it would start typical while(1) loop and work without FreeRTOS but

Hello Hello, I'm testing with the AT91SAM7xek evaluation kit. My final object will be communicating via Ethernet using TCP/IP. My first projects I made in IAR. Now I reached the 32kb compiler code limitation. Therefore I started with Eclipse. I can compile code, when I make the makefile myself. Now I'm trying to generate Eclipse my makefile. Therefore I have installed the plugin ARM ...

Hello Everyone, I'm woking on the USB Mass Storage device for the AT91SAM7XC256. I use the CrossWorks compiler and wanted to see if anyone else here has already converted demo aplication from the Atmel GCC USB Framework (and/or similar) for CrossWorks or if someone has their own and will share it? I lost one month of my life on it and it still isn'tworkning :-( . Thanks, Martin. Ps: I...

Hi all, I am generating my code with GNU-ARM.. I have searched and found that the solution to this struct mis-alignment problem is: __attribute__((__packed__)) Is there any compiler option, that would do the same for all structs I define? Or do I have to write this attribute to all of them? I found in gcc.pdf -fpack-struct Pack all structure members together without holes. Warning...

Hello group, I have an application where I need to force a section of code to a specific address for custom boot-loader purposes but can't seem to find out how this assignment is done using the CrossWorks compiler. There's examples out there for IAR but the two compilers seem to handle code location assignment differently. I'm trying to do this for both a SAM7S64 as well as for an Atmel A
