Hi All,

Sorry in advance for the long post. I have tried to include as much information as possible.

I am trying to create an OpenCPI environment for an Ettus E310.

The SD card has the original image from Ettus except the boot partition has been increased to allow room for the environment files.

I have copied the contents of the e31x/sdcard-xilinx13_4 to the boot partition of the SD card. When starting the Ettus there is no response from the screen serial connection.

Setup:

CentOS 7.8.2003

OpenCPI 2.1.0-rc.2 (2.1.0 final has released but my installation was done just before this)

Vivado 2019.2

Vivado 2013.4 SDK

opciadmin install platform xsim - success

opciadmin install platform xilinx13_4 - success

Built using AV GUI:

xsim - success

Build xilinx13_4. "Build Assemblies" option ticketed. (Note guide says only ocpi.core is needed for e31x)

ocpi.core - success

ocpi.asset - success

ocpi.asset_ts - success

My thoughts:

Is the 'ocpiadmin deploy platform xilinx13_4 e31x' environment generated correct?

When running 'ocpiadmin deploy platform xilinx13_4 e31x' command I get the below error. Could this possibly be affecting the generation of the E310 OpenCPI environment?

cp: cannot stat ‘../projects/assets/hdl/assemblies/testbias/container-testbias_e31x_base/target-*/*.bitz’: No such file or directory

I noticed in another forum post about SD card for the Zed that their environment contains 5 files (boot.bin devicetree.dtb opencpi uImage uramdisk.image.gz) where mine contains 3 (opencpi uImage uramdisk.image.gz). Are the boot.bin and devicetree.dtb files required?

Does the SD card need to be specially partitioned for the e31x environment?

The SD card starts with a boot (fat16) and root (ext4) partition. At the bottom of the E310 Installation Guide in Appendix A Generating Boot Artifacts it mentions that the default partitioning of the SD card isn't suitable for the Petalinux build. Does the OpenCPI Installation Guide use the Petalinux build? Also, the steps mentioning checking out ettus300-daisy. This no longer exists as a branch. devicetree.dtb and boot.bin are mentioned in this Appendix also.

What are the dependencies of the e31x setup?

Installation Guide uses xilinx13_4 and e31x as examples throughout the generic setup guide so my assumption is e31x is dependant on xilinx13_4. However it also mentions it uses xilinx19_2_aarch32 (Table of Supported Embedded Systems, Page 27 of Installation Guide). Is xilinx19_2_aarch32 a dependency for the E310?

Any help would be appreciated. Thanks in advance.

Unfortunately this problem was seen, identified and fixed after the release was cut.

The one-line fix is in this commit:

https://gitlab.com/opencpi/opencpi/-/commit/5915298a1943a98fcff67aceeeb813b938f06dd9

It is in the develop branch, but if you want to be surgical to avoid the churn with the develop branch, you could just make the one-line change in your repo for the time being.

Hi Jim,

Sorry for the delay in response, I have been attempting different avenues to try for a solution for this and wanted to respond when there was some progress.

Have you done:

ocpiadmin install platform e31x?

This command doesn’t work for some reason. In the end ocpiadmin install platform e31x -p ocpi.osps.e31x (or something similar) is the command that worked. I believe it is because e31x doesn’t exist in an immediate repository but is 2 repositories down (in ocpi.sps.e31x).

We recommend using (a raw copy of) the SD card as it comes from the vendor so the partitioning is however they like it to be.

SD card used is the raw copy of the vendor partition. It just appears to be corrupting constantly but a few e310 restarts or unmounts/remounts gains access to the SD card again.

I decided to rebuild my machine so reimaged CentOS7 then installed OpenCPI 2.1.0 (latest release), Vitis & Vivado and then did a ocpiadmin install platform xilinx19_2_aarch32, xilinx 13_4 and e31x. Put the SD card into the Ettus E310 with xilinx19_2_aarch32 e31x and did a source ./mysetup.sh and it sourced according to plan.

The problem comes when I do the ocpirun -v -t 1 -d -m bias=hdl bias.xml command

My thoughts are, does the bias.xml only work for xilinx13_4? What is this assertion failure? If I create a FSK application would that work? hello_world.xml worked as intended.

As a work around I attempted to use xilinx13_4 instead but I get an error when sourcing mysetup.sh:

Thanks for the comments so far, you have been a huge help.

Copied the updated line from the branch over to the respective file then did another install of OpenCPI and the m_port_size() error has disappeared.

ocpirun -v -t 1 -d -m bias=hdl bias.xml is now working as intended.

The next step is teh test application which doesn’t appear to be working.

Running the following two commands appears to fail:

./target-xilinx19_2_aarch32/FSK rx

Application properties are found in XML file: app_fsk_rx_e31x.xml

ERROR: No acceptable implementations found in any libraries for "ocpi.assets.devices.ad9361_spi".  Use log level 8 for more detail.

% ./target-xilinx19_2_aarch32/FSK filerw

Application properties are found in XML file: app_fsk_filerw.xml

ERROR: No acceptable implementations found in any libraries for "ocpi.assets.comms_comps.mfsk_mapper".  Use log level 8 for more detail.

My understanding is that xilinx19_2_aarch32 and e31x don’t use ocpi.assets as a dependency, only ocpi.core.

The dependencies are used during the ocpidev build commands, correct?

There is the FSK_App_Getting_Started_Guide and the FSK_App_Getting_Started_Guide_E31x.

I followed the later guide to build the FSK application.

The build commands also appear to be slightly different between the two guides. I have noticed that the former guide mentions fsk_modem in section 5 Build the assets project, which is the application you mention is required for the e31x.

Assuming that ocpi.core, ocpi.assets, ocpi.platform, and ocpi.osp.e31x projects have already been created:

If I use the commands in the FSK_App_Getting_Started_Guide while in the correct directories but replace xilinx13_3 and matchstiq_z1 with xilinx19_2_aarch32 and e31x respectively then  the fsm_modem application will be built? Will this solve the “ERROR: No acceptable implementations” error?
