Hello Prial,

From the SDK docs:

"There are two RPMsg software implementations provided in the Linux Processor SDK. On the ARM Linux side, RPMsg communication is received in kernel space. An interface module is provided (rpmsg_pru) that creates a character device in user space so that users can write/read to/from a character device in the file system to send/receive messages to/from the PRUs. "

Regards,

Nick
