Hi Ashish,
I also got the problem that my IDLE loop (backgroundLoop ()) stops at an undefined instant of time to work. All interrupts work fine but the backgroundLoop () isn't called anymore.
Is it possible that it is a stack problem? Would the SYSBIOS remind me in any way that it has an error and stops working now. I use the Blackhawk JTAG debugger, wouldn't run SYSBIOS in an interrupt trap which reminds me of the error?
kind regards
Anreas
