AM623: About memory allocation issues

Hello ,

I am looking at your queries and you may expect reply in one or two days .

Hello ,

The above memory is dedicated  for IPC communication.

So, when the A53 core wants to transfer data between cores. The M4F core can use these buffers to read the data.

This memory is used for IPC communication.

And, one more thing is that if you use DDR from M4F core, the M4F core performance is degraded 100 times.

Now I have A demand is going to 0x9CC00000-0x9CD00000 this piece of memory is used to do A core and M core interaction shared memory, so I hope this piece of memory will not be used by the program and compiler, how should I operate

Hello,

This memory has already allocated for IPC communication between the A53 core and M4F core.

In the driver, the  generated code belongs to IPC shared buffers and this memory is allocated to IPC buffers.

You don't need to take any extra steps to use this memory for IPC and already in MCU+SDK, have taken care of this memory for IPC communication and not for any other code.

Anil.

ok,thanks
