On the December 19 call, I committed to sending the instructions I had provided to the Linaro LITE team to build a bootable image that can be used to develop and test OpenAMP with Linux on Xilinx QEMU.

I am using this setup to work with Paul Sokolovsky on getting CI for OpenAMP on QEMU using LAVA.

This is a first cut. Feedback is welcome.

As you sent the instructions as an attachment I can't reply inline but I will fake it.

Should we make it a policy to send everything on this list in plain text with files as patches?

# Building the image

In the build directory (<path to repo>/build):

$ bitbake openamp-image-minimal

To get this at least started I used:

$ MACHINE=zcu102-zynqmp bitbake openamp-image-minimal

The instructions above leaves a default machine of qemuzynq which does not exist. There is a qemu-zynq7 but I don't think that is right. From the name of the output image I am inferring that you want the zcu102-zynqmp machine.

Please confirm or deny this assumption. Thanks.

This is correct. I goofed and omitted the step of selecting the machine from the instructions. I have corrected this.

**** What version for openamp/* git sources?

When I did my build, I pulled everything from the rel-v2019.2 branch from the Xilinx GitHub. The Xilinx build process builds the R5 binaries using the Xilinx toolchain, and pulls it out of the embeddedsw repository.

Right now I have the three dirs in the openamp dir as follows:

bill@rocky:~/w/proj/openamp/ci-xilinx$ for d in openamp/*; do (echo "*** $d"; cd $d; git remote -v; git status); done *** openamp/embeddedsw origin https://github.com/Xilinx/embeddedsw.git (fetch) origin https://github.com/Xilinx/embeddedsw.git (push) On branch master Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean *** openamp/libmetal origin https://github.com/Xilinx/libmetal.git (fetch) origin https://github.com/Xilinx/libmetal.git (push) On branch master Your branch is up to date with 'origin/master'.

Can you please document what you are using and have tested.

I have tested remoteproc and rpmsg with the 2019.2 build from the Xilinx GitHub repositories.

I have also tested with the OpenAMP project repositories for the Unix side, and it works. I have not yet tested the R5 side from those repositories. That will happen soon.

One of my goals is to put together a complete open source toolkit for building R5 and Linux OpenAMP applications, along with the Linux kernel, and create a deployable image for use with the Xilinx QEMU docker image. This set of instructions was a first step. It also helps enable a LAVA CI loop for OpenAMP.

Thanks, Bill
