Subject: rel-v2018.03: openamp-image-minimal build fails due to kernel config
 
Wendy & all,
 
I am trying to build the openamp-image-minimal for my Ultra96 board.  I am using the rel-v2018.3 release from the Xilinx yocto-manifests.  My desktop machine is Ubuntu 16.04 64 bit.  I have no Xilinx SDKs or design tools installed.
 
When I build this image the resulting kernel does not have the needed modules and this results in a failed do_rootfs.
 
I am using the zcu100-zynqmp machine.  Is there a different machine that works for this image? I see the linux-%.bbapend in the openamp layer.  Do I need to manually add the distro features to my local.conf?  Do I need to use a different kernel as the base?
 
I can probably hack this up so it works but I would like to understand how it is supposed to work.
 
$ MACHINE=zcu100-zynqmp bitbake -k openamp-image-minimal

[Wendy] Did you enable those modules from Linux kernel configuration?
Maybe, the openamp-image-minimal, can have a kernel bbappend to enable those kernel modules in recipes-kernel/linux/openamp-kmeta/cfg/ of meta-openamp.

Thanks Wendy.  I had looked at this configuration in the mean time.  I needed to enable these items by adding to distro features.  However, that still resulted in the above errors.  The issue with the three modules above is that they are built in to the default Xilinx kernel for these machines.  I thought OE would figure that out but I guess not.  Even if I were to remove those packages from the image dependencies it would still not work because the line that adds the platform level rproc driver is commented out in that image recipie.

[Wendy] yes, just tried to remove platform specific setting from this recipe. As they can be covered by platform specific meta BSP layer.
I was thinking to just keep the common setting in meta-openamp.
Actually, I have tried openamp-image-minimal, but I cannot see the issue.
I  had thought you may have used a different kernel. 
I assumed you used https://github.com/xilinx/yocto-manifests/tree/rel-v2018.3. I haven't compared the HEAD of your layers with mine.
Will check it.

Best Regards,
Wendy

So I gave up on openamp-image-minimal and just added the needed stuff to petalinux-image-minimal via local.conf.
I now have an image for zcu100-zynqmp built OK but I have not tried it.  I did verify it has all needed modules builtin or it lib/modules and it has the libmetal and openamp libs and demo apps.



The last bit of my local.conf looks like:
>>>
DISTRO_FEATURES += " virtualization xen openamp openamp-experiment-virtio-rpmsg-char"

INSANE_SKIP_glibc-locale = "installed-vs-shipped"

IMAGE_INSTALL_append += " open-amp libmetal kernel-module-zynqmp-r5-remoteproc kernel-module-uio-pdrv-genirq libmetal-demos open-amp-demos"

<<<<
$  MACHINE=zcu100-zynqmp bitbake petalinux-image-minimal

The rest of local.conf is as setup by Xilinx's setupsdk script.

The xen and glibc stuff is because I am separately experimenting with xen.  That should probably be a different thread.

Thanks,
Bill
