Hi everyone i am fresh to the at91sam7a3,I try to use WINARM to compile example about sam7a3.i found there is examples about sam7s64 in Examples provided by Winarm.then i modified it to use headerfile of sam7a3.Now it can build project sucessfully.i get an bin file by modifing makefile.but it couldnot work after i download to the EK board.Does any one else have good examples on at91sam7a3-EK board?

My GNU-ports of the SAM7S-examples provided by Atmel may serve as templates how code for EWARM or RDKARM can be adapted for the GNU tools. Martin Thomas

Well, give all information and I will try to understand better. In the first message you have written that you try to tried to port a SAM7S example that comes with WinARM to a SAM7A by just replacing the header-file. How could I know that you already have the examples for IAR and already use IAR EWARM and you now try to port an example for IAR to the GNU-tools? You do not give any details about what you have "modified" (in the code for IAR? in the WinARM-example?). Did you check the startup-code (compare with the code for IAR) and the linker-scripts (memory-sizes/locations)? Search this forum, as far as I remember, there is already some information about creating code for a SAM7A with GNU-tools available.

Here ya go: http://users.wpi.edu/~jimmykaz/Arm/Sam7A3_Virt_Fnct.rar This should include everything you need to get you started on the SAM7A3. Hell, it even works with C++ and virtual functions (thanks again to Martin for helping me to get that working)!
