AM5729: Regarding Program Counter address

PETA MAHESWAR REDDY

Part Number: AM5729

Tool/software:

We are using TI RTOS SDK AM5729. Our Code Execution : 0x80000000 to 0x90000000. But we are observing Program counter value 0x0003FF04. How can we identify from where it modified program counter. is there any debug approach. Even we tried to get Task Stack, unable to get data.

It seems to be an issue with exception handling. Could you please connect to the CCS to identify which specific API is cause this?

We tried to connect it but we cannot find anything, can you help us in debug how to find specific API to cause this issue.

Open CCS and start your debug session, Load your program.

Set a break point place a breakpoint early in your application, possibly in main()

When you hit a breakpoint or pause the core , Use "Step Into" to go into function calls line-by-line or Use "Step Over" to it run a function without entering.

If the program counter jumps to an unknown/invalid address (like 0x0003FF04), or CCS halts unexpectedly, then look at the disassembly and call stack to see which function was last executed.
