We just upstreamed a general SPI master/slave solution you can use directly or as a reference: https://github.com/apache/nuttx/blob/master/drivers/rpmsg/rpmsg_port.c https://github.com/apache/nuttx/blob/master/drivers/rpmsg/rpmsg_port_spi.c https://github.com/apache/nuttx/blob/master/drivers/rpmsg/rpmsg_port_spi_slave.c It is based on rpmsg, so it can work with nuttx-nuttx and linux-nuttx and all rpmsg services can work very well. For the detailed info, you can watch the topic come from NuttX workshop: Day2: 02 - Linux to NuttX communication in Xiaomi (youtube.com) <https://www.youtube.com/watch?v=-YLAQlJR1vA&list=PLd73yQk5Fd8JJ5vfwN9z16emlqm36bNNF&index=18> Day2: 07 RPTUN_framework_&_services_between_multi-CPUs (youtube.com) <https://www.youtube.com/watch?v=6uehz3WQ0vU&list=PLd73yQk5Fd8JFJW0cIHsDcG-kd6OHiHEz&index=17> Day2: 03 NuttX VirtIO Framework and Future Works (youtube.com) <https://www.youtube.com/watch?v=CYMkAv-WjQg&list=PLd73yQk5Fd8JlsCoUYGyAf7W63BekgPup&index=8>
