Introduction to OpenAMP
summary
OpenAMP provides an open source framework that standardizes lifecycle, firmware loading and IPC between heterogeneous cores, implementing remoteproc/rpmsg and running in userland so Linux is no longer the only master. It uses libmetal for hardware abstraction and virtio transport options, supports Zephyr FreeRTOS bare‑metal and Linux, exchanges short rpmsg control packets (~500 bytes), can boot and quiesce remote cores, and is adding DMA/zero‑copy for high‑volume data; project is active on GitHub and still evolving.
