8 Build an application
The setup of the platform can be verified by running an application that uses both RCC and HDL workers. A
simple application that requires two RCC and one HDL worker is located in assets/applications/bias.xml, but
only the RCC artifacts are provided with the installation of RPMs, and are availble on the SD card (Standard
Mode) or mounted CDK directory (Network Mode). The remaining task is to build an assembly, or bitstream for
loading the FPGA, which contains the HDL worker.
9 Run an Application
9.1 Network Mode
The default setup script sets the OCPI_LIBRARY_PATH variable to include the RCC workers that are required to
execute the application, but it must be up dated to include to the assembly bitstream that was built. After running
the mynetsetup.sh script, navigate to /mnt/ocpi_assets/applications, then update the OCPI_LIBRARY_PATH
variable using the following command:
$ export OCPI_LIBRARY_PATH=/mnt/ocpi_assets/artifacts:/mnt/ocpi_core/artifacts
Run the application using the following command:
$ ocpirun -v -t 1 -d -m bias=hdl bias.xml
The output should be similar to:
Available containers are: 0: PL:0 [model: hdl os: platform: e3xx], 1: rcc0 [model: rcc os: linux
֒→ platform: xilinx13_4]
