To boot prebuilt Linux for Versal® ACAP, follow these steps:

  1. Generate BOOT.BIN for Versal ACAP.
    petalinux-package --boot --plm pre-built/linux/images/plm.elf --psmfw pre-built/linux/images/psmfw.elf --dtb pre-built/linux/images/openamp.dtb --u-boot -o pre-built/linux/images/BOOT.BIN --force.
  2. Boot Linux
    petalinux-boot --jtag --prebuilt 3 --hw_server-url <hostname:3121>

To boot prebuilt Linux for Zynq® UltraScale+™ MPSoC, follow these steps:

$ cd <plnx-proj-root>
$ cp pre-built/linux/images/openamp.dtb pre-built/linux/images/system.dtb
$ petalinux-boot --jtag --prebuilt 3 --hw_server-url <hostname:3121>

Once Linux is booted, run the following commands for Versal devices only:

  1. modprobe virtio_rpmsg_bus
  2. modprobe zynqmp_r5_remoteproc

To load OpenAMP firmware and run OpenAMP test application, run the following command:

$ echo <echo_test_firmware> > /sys/class/remoteproc/remoteproc0/firmware

For example, to load image_echo_test, run:

$ echo image_echo_test > /sys/class/remoteproc/remoteproc0/firmware
$ echo start > /sys/class/remoteproc/remoteproc0/state
$ echo_test
$ echo stop > /sys/class/remoteproc/remoteproc0/state
To stop running, run the following command:
$ echo stop > /sys/class/remoteproc/remoteproc0/state
