Hi
I have just ported my code that was working without a RTOS to CMSIS RTOS and its loaded onto my cortex m3 arm and my code gets through by board initialization but as I get a stack overflow when the RTOS tries to start the first task.
I have configured 0x8200 bytes for my stack, 7 tasks, 2000 bytes for the default thread and 800 bytes for the other 6 threads. The thread viewer shows two additional threads, timer and idle. My stack is located in the esram and is using all available bytes there.
I really do not have any idea what I have done wrong in allocating memory for the stack or in configuring the RTOS. I feel I missed something in the setup.
I was thinking about backing off the 7 threads and just try to start 1 and see if that overflows.
Is it possible to relocate my stack to my DDR memory space at 0xA0000000 so I can make the available stack size bigger? I don't know if throwing more memory at it will really solve this problem.
Does anyone have any ideas about what might be wrong or how I might go about debugging this overflow issue?
