sync issue between A7 and M3 on RZN1D

Hi,

We are using RZN1D Eval kit for firmware development. We have created the share memory at 0x200F8000 location.

In firmware, A7 core is writing to share memory and M3 core is reading the data from same location and sending the same data though USB to other board.

When we are running application on A7 though terminal and M3 core through IAR debug simultaneously.

We have found that the following issue and this are randomly occurring

1) USB is not initializing

2) Ethernet is disconnecting when M3 is in debug mode

3) Terminal is getting hang when M3 is in debug mode

Also, i wanted to know how to run the M3 core in release mode (without debugger).

Thanks,

Mayur
