I hope to enable A72 and MCU to exchange data,sdj version is 08-06.app_fd_exchange demo use shared memory to exchange data 

Hello,

Sorry for the delay. You are using LINUX on A72 and communicating with MCU domain core right ?

if so can you see the URL for better understanding https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/09_00_00_08/exports/docs/linux/Foundational_Components_IPC_J721E.html

Do I need to use rpmsg for communication with IPC? If I want to have communication similar to MCU and A72, is there a related demo?There is only theory here, not actual operation, thank you.

My code logic is to fill the data object sent by the sender, such as vx_user_data_order, with data, and then obtain the handle using tivxxReferenceExportHandle on the receiving end. After obtaining the handle, I use vxCpyUserDataMata to interpret the data. Theoretically, the handle should be able to be read normally, but the information read is not the information I sent.I implemented data filling in the AppAllocObject of the producer。The transmitted content is as follows.Implementing Data Interpretation in Consumer's App_create ObjFromBuffInfo FunctionThe obtained data is as follows

Hi,

Could you please check from the received fd at consumer if the physical address is same as the one allocated by the producer?
