Hi guys ,

I'm newbie with freertos and i need some help.
I just received a Atmel board AT91SAM7S-EK with jlink and IAR tools, and now i'm trying to get the demo app running on my board ...

The project compiled OK , but when i clicked to download and debug, i' m receiveing a message that notice warnings while generating flash loader.

I clicked OK , and after that another message:

Programming failed @ address 0x00100100

So , after that , it seems to be loaded , but when i clicked Go, the demo app didn't work .

here my debug log :

Any ideia to solve this problem ? What i supposed to do ?

Thanks in advance

First check that the hardware is working correctly by downloading one of the examples that IAR supply to flash. If the hardware is working then it sounds like there is a configuration problem somewhere probably caused by the project being created in a previous version of Embedded Workbench. You could check the configuration of the linker script and j-link macro files against the working project.

I've just tried IAR V5.4 with the SAM7X demo in the FreeRTOS download. I had to make a couple of changes to get it to flash and run correclty. Although I cannot explain exactly why some default deep within the IAR configuration seems to have changed regarding the remapping of vectors.

If you update your Demo\uIP_Demo_IAR_ARM7 from the SourceForge SVN repository you will get the changes necessary. This includes a new macro file called at91sam7x-ek-flash.mac and a change the the linker script at91SAM7X256_FLASH.icf.
