// This is the symbol name for the SOF file contents linked in. 

extern char _binary_soc_system_dc_rbf_start; 

extern char _binary_soc_system_dc_rbf_end; 

 

 

// Use the above symbols to extract the FPGA image information. 

const char * fpga_image = &_binary_soc_system_dc_rbf_start; 

const uint32_t fpga_image_size = &_binary_soc_system_dc_rbf_end - &_binary_soc_system_dc_rbf_start; 

 

how does it extract the FPGA image information ? 

where the FPGA image ? 

 

thanks!
