CCS/OMAPL138B-EP: load the Executable program on DSP can't go main

Part Number: OMAPL138B-EP
Other Parts Discussed in Thread: OMAPL138

Tool/software: Code Composer Studio

Hello, 

I'm using CCS3.3.82 to load the readwrite sample of OMAPL138, i have modified the memory map and the sample source code, when I  load the .out  in the board, the Disassembly  window can't go to the main().  

as it shown in the below:

I try to Single step debugging in the disassembly window, but it loop in BCACHE_block and BCACHE_wait  and can't go main;

When I close the MSGQ and POOL in the DSP/BIOS,  it can go main and run.

Is there anything wrong about the MSGQ and POOL? How to solve this problem?

I'm waiting for your answer, thanks! 

Regards,
