SPLOOP and simulator/EVM Board on OMAP L-137/C6747

Zuofei Wang

Hi,

I am going to optimize my program with SPLOOP Buffer in OMAP L-137/C6747. Now my problem is: my assembly code runs perfectly on the "C674x CPU Cycle Accurate Simulator" (with CCS v3.3). But I always get the wrong result whenever I run my program on real OMAP L-137 EVM board.

I was wondering if there is something that needs to be noticed when using SPLOOP on real OMAP L-137 EVM board.

Thanks.

Hi Zuofei,

Could you please provide some more detail on your program? If there is a short code segment that you know is having this issue, please feel free to post the code segment here or send me a personal message. Our expert will look into that.

Please also explain what you mean by wrong result.

Thank you Paul,

How could I send you a personal message on forum?

I used a C program to compare the result with my assembly code. The C program and my assembly code outputs the same result in the simulator, but the output of assembly code is wrong on real EVM board.
