What Lopper Generates from OpenAMP YAML - What Lopper Generates from OpenAMP YAML - 2026.1 English - UG1186

When you run Lopper on the OpenAMP overlay YAML, it generates device tree content for Linux and the remote OS.

• For the Linux device tree, Lopper generates:
  • /reserved-memory nodes for all shared regions, including ddrboot, rsctbl, vdev0vring0/1, and vdev0buffer
  • IPI mailbox controller and child channel nodes under /axi
  • A remoteproc node with memory-region, sram, mboxes, and mbox-names properties
  • TCM nodes with sram phandle references
• For the Zephyr or remote device tree, use -- openamp <cpu> zephyr_dt:
  • /reserved-memory with ddrboot as mmio-sram
  • /reserved-memory with ipc as combined vrings and buffer, also as mmio-sram
  • An IPI mailbox node with Zephyr-compatible bindings, such as xlnx,mbox-versal-ipi-mailbox
  • An mbox-consumer node or mbox_ipi_* node, depending on the Lopper version
  • A chosen node with zephyr,sram, zephyr,ipc_shm, and zephyr,ipc properties
