TMS320F28386S: IPC driverlib Message Queue Support

Ramon Martins

Part Number: TMS320F28386S
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Hi there, good morning.

I am working with the TMS320F28386S microcontroller, using sysconfig and driverlib provided by C2000Ware version 5.0.0.0. As a good practice, I don't change any driverlib's file, therefore I chose to import the driverlib directly from the SDK's directory.

My project demands larger messages than the ones provided by the driverlib. It's not necessary to use the message queue support, but to deactivate the message queue support to free some memory seems like I have to edit the ipc.h file from the driverlib. Is there any way to deactivate, increase the size of the buffer, and other configurations of Message queue without changing the ipc.h file? If not, I suggest this and including IPC to CM for future sysconfig's option. (It currently only has IPC to CPU1-CPU2 Communication).

Thanks. Ramon.

Ramon,

Have you taken a look at the ipc_ex1_basic example? As part of the send_command function, you are able to pass the length of the data to be read. Since you do not need the message queue, I would recommend this method of passing data between cores.

Hi Benjamin,

Thank you for your answer, I have already tested the 'ipc_ex1_basic' and 'ipc_ex2_msgqueue' examples, and they work fine, however the problem that i would like to deactivate the message queue support to free the 272 bytes reserved by the 'driverlib' for each message RAM.

Best Regards,

Hi,

You need to recompile the driverlib with macro IPC_MSGQ_SUPPORT set to 0. The macro is defined in ipc.h

Hi Veena,

Thank you for your answer, as i commented before, as a good practice, if possible i wouldn't like to change any driverlib's file(including the "ipc.h" header file), is that possible?

Thank you for your guidance,

Ramon.

Hi Ramon,

I dont think there is another way to disable MSGQ support.
