Zephyr and OpenAMP
summary
Sets up Zephyr on a Cortex R5 and loads it from an A53 running Embedded Linux on a Zynq Ultrascale+ (Digilent Genesis ZU), using OpenAMP’s remoteproc on Linux and rpmsg/virtio on the Zephyr side. Key fixes are enabling resource table required in the build, correcting SRAM offsets and mailbox nodes in the device tree overlay, and adding the Zephyr binary into PetaLinux. Debugging uses Vitis with manual symbol setup. Result: Linux starts the R5 Zephyr image and an echo roundtrip works (message sent and received).
