Hi wendy, Thanks for replying. I have already enabled remoteproc, rpmsg and virtio in the kernel configuration. I have also added CORE_IMAGE_EXTRA_INSTALL += " \ kernel-modules \ " In my local.conf file. I generated BOOT.bin file from bootgen.bif file after adding the rpu firmware: [destination_cpu=r5-0] <path to RPU firmware> While booting the device I didn't see r5 code being booted. Now I am trying Building Linux Applications Using OpenAMP RPMsg in Linux Userspace Using meta-openamp layer. I found that there is a patch "Add Xilinx ZynqMP R5 remoteproc driver.patch" to have a53 and r5 communication. Is this patch required for the purpose of openamp in userspace? This patch was missing in meta-xilinx and I brought it to my custom layer, but it failed to apply giving the following error: error: include/linux/firmware/xlnx-zynqmp.h: does not exist in index | error: include/linux/firmware/xlnx-zynqmp.h: does not exist in index | error: include/linux/firmware/xlnx-zynqmp.h: does not exist in index | error: drivers/firmware/xilinx/zynqmp.c: does not exist in index | error: include/linux/firmware/xlnx-zynqmp.h: does not exist in index | error: drivers/firmware/xilinx/zynqmp.c: does not exist in index | error: include/linux/firmware/xlnx-zynqmp.h: does not exist in index | [ERROR]: Application of .kernel-meta//patches//./0276-Add-Xilinx-ZynqMP-R5-remoteproc-driver.patch failed. | Patch needs to be refreshed.

Also is this patch for the kernelspace implementation or userspace implementation. [Wendy] the r5 remoteproc driver is to load RPU firmware from linux, and for RPMsg in kernel space implementation. It is not required for userspace implementation. >From your error message, it looks like you don't have : >include/linux/firmware/xlnx-zynqmp.h in your kernel. Did you use linux kernel from github.com/xilinx? And I am using tftp boot. I think that if r5 was able to boot it should show me while booting as I am serially connected to the device. [Wendy] if you want to boot R5 from Linux, you will need to use r5 remoteproc driver to do so. By default, Linux will not auto boot R5. Best Regards, Wendy Please provide any pointers on this. Has anyone implemented this using meta-openamp layer and no petalinux.

It compiled successfully. I also add rpmsg-echo-test, rpmsg-mat-mul , and rpmsg-proxy-app packages in the image and it successfully compiled. I am building Linux Application that uses RPMsg in user space. Now the executable generated from echo-test or mat-mul are in my host linux master (a53-core). I have also created an r5-application using XSDK. What is the next step to have a communication between a53 and r5. How to use the generated elf file for r5 processor. Also I have enabled remoteproc, rpmsg, virtio in kernel configuration. But while using the command " $modprobe zynqmp_r5_remoteproc", I get the following error: "modprobe: module zynqmp_r5_remoteproc not found in modules.dep" [Wendy] It doesn't look like the zynqmp_r5_remoteproc driver is compiled or maybe it is compiled but not add into the system. Please check the following: * If your linux kernel has enabled in your kernel .config * If you have "kernel-modules" added to your image o E.g.: o CORE_IMAGE_EXTRA_INSTALL += " \ o kernel-modules \ o " Best Regards, Wendy How can I boot the r5 processor and where to store the elf file generated.
