    Hi Lu Zhiang,

    RPMSG packet/message max size is 512bytes. This means that in one message you can send max of 512bytes. You can send as many messages as your application can process.

    For use cases where you need to send more than 512bytes of payload in one message, please allocate a buffer for the payload data and pass pointer to the buffer in rpmsg message/packet. In this case the buffer pointer becomes part of the 512byte sized packet communicated to the remote core. Application running on the remote core can access the payload from the pointer received in the packet.

    Thanks & Regards,

    Sunita.
