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

[mmmtq2011]

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

Hi Mohammed

one can look at additional documents and examples from third parties:

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.
