Hi,
My application under TI RTOS runs for a while then it terminates. Please see the screen capture below. My platform is the Tiva C Launchpad EK-TM4C123. (This box does not allow me to copy a screen capture?)
My application can run from a few seconds to about 40 minutes before it terminates. In my application, a hardware interrupt comes in from Port C periodically once every 3 mS. It calls the ISR handler syncManagerISR(), then some SPI transfers take place. Please see the code file attached.
In the stack dump. It always starts from 0xFFFFFFFC. I don’t know how to interpret the register dump in the Console window.
I am new to TI RTOS, could you give me some tips on how to debug this problem?
Thank you.
Jonathan
