TDA4VM: Linux and mcu1_0 ipc problem

eason zhou

Part Number: TDA4VM

Tool/software:

SDK version 0806

Board: tda4vm_evm


Hello TI experts,

we are currently encountering a problem. We want an IPC communication based on MSMC  for Linux and MCU1_0 ipc (we do not want to use DDR). 

We hope that TI experts can provide some demo support.

(How to configure and use msmc on mcu1_0 with linux)


thanks

Hello,

1) Make sure you are not using MSMC in any other application which can create conflict, usually TIDL applications use MSMC.

2) You can modify the common shared locations in both application of MCU1_0 and in dts file of linux.you will have shared pool that you have to use

Hello,

Currently we don't have any existing demo the keep shared as MSMC instead of DDR. Please have a look into above mentioned file in linux sdk and modifying as we did for DDR.
