Using Shared Memory (S0-S7)

André Ramos

Hello. I am working with f28m36x and I want to do a communication between M3 and C28 cores, using 8 blocks from Shared Ram Memory. I found ram_manegement example, but I don't understand how does it work. Now I am trying to now about IpcMgr. This module is the same used in MessageQ. So, if someone know to use shared memory can you help me?


Thanks in advance,

André

    Andre,

    The TI-RTOS forum is no longer the place for IPC related questions. I have moved this tread over to the device forum in hopes that you can get a faster response there.

    Hi,

    Shared RAMs are like normal RAMs which can be used for data a well ass code execution. These are shared between M3 and C28x subsystem. All the master have read permission to these RAMs but for write/code execution, master need to have the ownership of the RAM block. By default M3 subsystem has master ownership for all the shared RAMs. Please refer "RAM Control Module" section for more detail about shared RAMs.

    If you have specific queries about the usage of these RAMs or about the example code, please let us know.

    Regards,
