Hello Xiang Xiao, thanks for sharing with me about rpmsg, to be honest it is new for me =/, I was locked in baremetal for several years. For now I cannot use it because my host mcu is running baremetal (maybe in the future we will change it). I developed a simple protocol using ack and nak whey to handle communication with master and slave. About "lock" my app until data is available, I am thinking use semaphore to wait to do it, so my solution will be able to sleep my mcu until spi releases it.
