The OpenAMP framework provides this missing fu nctionality by providing the infrastructure required for FreeRTOS and bare-metal environments to communicate with the Linux Kernel in AMP systems. Inquiries regarding membership in the Multicore Association and participation in this and other working groups should be made to Markus Levy (markus. ultra96_zynqmp. RPMsg Overview In asymmetric multiprocessor systems, the most common way for different cores to cooperate is to use a shared memory-based communication. Different solutions have been evaluated, including but not limited to OP-TEE, dualoscom, RPMsg, and OpenAMP. This talk describes an architecture and implementation for transmitting large buffers using RPMsg. It should be recalled that this choice is reversible, in the sense that if application-specific requirements can not be met by RPMsg, it. 建一个rpmsg通道 {% codeblock lang:c %} OPENAMP_create_endpoint(&resmgr_ept, RPMSG_SERVICE_NAME, RPMSG_ADDR_ANY, rx_callback, NULL); {% endcodeblock %} 注意这里的RPMSG_SERVICE_NAME和驱动里rpmsg_device_id结构体的.

While you can send the received data from the MCU on the main serial port, you can also see the data received from the MPU on the secondary serial port. ACSYS offers a large set of courses on ST processors. OpenAMP also have remoteproc support for RTOS/baremetal, but you will need to implement the remoteproc driver For your platform > * Rpmsg is used to create a channel between the remote CPU and one driver. It provides common user APIs to access devices, handle device interrupts, and request memory across different operating environments. OpenAMP supports shared memory protocols (virtio and rpmsg), IPC, resource management and sharing, and process control (remoteproc). Random presentation slides I found on the topic:.
