MSGQ Link Error

Dennis Nguyen

Hi,

I just got an C6747 starter kit. I am using CCS v3.3 and BIO 5.33.05. I am trying to do a couple things and it failed right away. MY steps are:

1. Use current example from evm6747 audio. Compiled ok.

2. Added 2 new tasks. Compiled ok.

3. Enable MSGQ Manager. Compiled and got link error with "_MSGQ_config undefined symbol"

I must missed some basic configuration somewhere but I can find any information on this.

The message Queue module needs this structure to be defined in the application. MSGQ_config is a required global variable.

Please see section 2.19 of:

You can take a look at the provided examples that come with the DSP/BIOS installation:
