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:
