[yocto] bitbake openamp-image-minimal fails to create image

[Pandey, Kamal]

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

Now the Xilinx document UG1186 never mentioned about this patch or driver. Also is this patch for the kernelspace implementation or userspace implementation.
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.
Please provide any pointers on this. Has anyone implemented this using meta-openamp layer and no petalinux.
Thanks

Hi,
I solved the problem by using meta-openamp(branch should be similar to xilinx version) layer in my yocto project and enabled "libmetal" and "open-amp" packages in my image recipe. 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.

Hi Kamal,

Seems like the required kernel modules are missing causing the breakage.
Enable them using kernel menuconfig (bitbake virtual/kernel -c menuconfig) and then build the image

Thanks,
Manju

Hello,
I used the meta-openamp layer for r5-a53 communication.
but when I simply ran $bitbake openamp-image-minimal, it gave me the following error:
