Other Parts Discussed in Thread: OMAPL138

HI,

I had gone through Sample application in DSPLink 1.65. I am using OMAPL138.

   then I run the example of messages,when the structure of message is
           {
                MSGQ_MsgHeader msgh;
                 unsigned int puf[10];
           }
I can send message to arm;

when the structure of message is
           {
              MSGQ_MsgHeader msgh;
               unsigned int puf[60];
           }
I can not get the right result , but why ? ???????

What is the size of your pool you are using to allocate the message?

What is the size of the blocks in the pool? You might need to increase this to something larger than your new message size. Note: I'm assuming you changed your size parameter in your MSGQ_alloc call.

thank you,but there is another question about MSGQ: I saw that I can design more than one allocator in different memory block,but how?

You can have multiple pools in a system. They each manage a specific block of memory. Please refer to the BIOS User Guide documentation, DSPLink documentation or DSPLink examples.

Hi Todd:

Could you please point me to the DSPLINK documentation and examples? I am developing code on the OMAPL138 under CCSv5.

Thanks a lot!

Hi Fuliang:

I am interested in using DSPLink under Code Composer Studio 5 (CCSv5) on the OMAPL138. Could you please let me know how to go about setting up DSPLink under CCSv5?

Could please point me to any documentation that may help me with this?

Thanks a lot!

Cheers,

Mushtaq
