Hi there fellas,

I am new to FreeRTOS and trying to develop my first application. I am using AT91SAM7X256 and my program has just on task, just an endless loop of vTaskDelay(100) in the body of task. I debugged the program with a JTAG debugger and every thing works fine until I enter to the body of function and BAM! I find myself at memory address 0x10 which has an "b 0x10" instruction at it and serves data abort interrupt. I am sure that vTaskScheduler starts in SVC mode.  
Any suggestions?  
thanx.

Please do not post the same question twice.&nbsp; There is already a response to this in the original thread.
