I’m using the FreeRTOS port AVR32 UC3A0512 (Atmel EVK1100 Starter Kit)! In my application i two interrupt service routines which manage the RS232 traffic like in the demo application. Everything works fine with no RS232 traffic. With RS232 traffic Free RTOS crashes after an undefined time. Sometimes the Application runs half an hour with a lot of RS232 traffic before RS232 crashes. When a crash occours and i stop the Application in debug mode (Jtag mk II) one of the following execptions is viewed:
“Bus error data fetch” or “Bus error instruction fetch”
Has any one a solution for this problem or can anyone give me a help to isolate the failure!?!
Thanks in advance!
