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,

Satoshi Shimoda

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 .

Regards,

Sharmila
