Altera-SoCFPGA-HardwareLib-FPGA-CV-GNU example

Hello.

I am engaged in software development for the ARM core board Cyclone V SoC Development Kit. I am interested in an example of Altera-SoCFPGA-HardwareLib-FPGA-CV-GNU, which loads firmware FPGA from DMA and launches baremetall application on ARM (FPGA toogle LEDs). This project is built using Makefile. In turn, we have made the project among DS-5, setting all options for the assembly of the Makefile, and copying everything you need to build the source code into a single folder. In the original example declares two external variables:

extern char _binary_soc_system_dc_rbf_start;

extern char _binary_soc_system_dc_rbf_end;

they point to the compressed firmware file for FPGA soc_system_dc.rbf. But this advertisement, we never found ourselves variables _binary_soc_system_dc_rbf_start and _binary_soc_system_dc_rbf_end. The original example is compiled and in debug mode works well. Can you clarify how these variables can be properly used in our project. Thank you.
