Hi community,

I have a question about i.MX6SX.

Acctually, our customer want to pass data from M4 core to A9 core, or A9 to M4.

What module can be used this usage?

(e.g. OCRAM, DDR, MU, etc...)

Best Regards,

Hi Satoshi

shared memory is used for data communication between cores,

please refer to attached document Chapter 53

i.MX 6 SoloX Multi-Core Communication (MCC)

and Figure 53-1. New multi-core, multi-OS architecture

Hi igor,

In Remote Processor Messaging (RPMsg), IPC APIs is supported in software ? How secure it is ? I am planning to use sc_ipc_open() sc_ipc_read(), sc_ipc_write() APIs for communication between Cortex A-35 to Cortex -M4. Can you please suggest on this .
