Hi Cesar,

The rpmsg_chrdev device is not created from device-tree. The device is created when a firmware announces an end-point with this device name.

Hello,

May i know what exactly is your doubt here ?

rpmsg_chrdev is created when the other R5 cores announces their announces their endpoints with the device names.

The remote processor announces the existence of a remote RPMsg service by sending a name service announcement message containing the name of the service (i.e. name of the device), source and destination addresses. The message is handled by the RPMsg bus, which dynamically creates and registers an RPMsg device which represents the remote service. As soon as a relevant RPMsg driver is registered, it is immediately probed by the bus and the two sides can start exchanging messages
