how to build the rpmsg A9 side program on i.mx 6sx

Hi,

I'm trying to write a code that sends data from the Cortex-A9 processor to the Cortex-M4 processor, then the Cortex-M4 processes it, then sends the processed data to the Cortex-A9. I've run the PingPong example on M4, and it works by executing some commands from the A9 side. but I want to write a code that sends the data without using these commands. I've checked this sample and this document, but I can't relate between them. I'm not really sure Where can I start to write the Linux rpmsg code on the Cortex-A9 processor, and I'm really short on time. 

Best Regards,

Mohammed

Thank you for your response, but I've already run the pingpong example on the M4 using the commands from the A9 side. What I want is to write a simple code on linux to transmit some data from the A9 to the M4. I want to do the communication in my application on linux.

Thank you for your response, so there are no documentations/examples about making the linux side of the rpmsg application ?

I've checked this code, I've tried to compile it using Eclipse with GNU ARM add-on, but it seems that sys/termios.h is missing, this causes an error by the compiler and I'm not really sure how to fix it.
