Load Path

To specify additional directories, use one of the following options:

x Current working directory from which LibGen was launched.

x Set the EDK tool option -lp. LibGen looks for drivers, OS’s and libraries under each of

the subdirectories of the path specified in the -lp option.

LibGen uses a search priority mechanism to locate drivers/libraries, as follows:

1. Searching the current working directory:

a. Drivers: Search for drivers inside the drivers or pcores directory in the current

working directory in which LibGen is invoked.

b. Libraries: Search for libraries inside sw_services directory in the current

working directory in which LibGen is invoked.

c. OS: Search for OS’s inside the bsp directory in the current working directory from

which LibGen is invoked

2. Searching the repositories under the library path directory specified using the -lp

option:

a. Drivers: For drivers, search <library_path>/<Library Name>/drivers and

<library_path>/<Library Name>/pcores (UNIX) or <library_path>\<Library

Name>\drivers and <library_path>\<Library Name>\pcores (PC) as specified

by the -lp option.

b. Libraries: For Libraries, search <library_path>/<Library Name>/sw_services

(UNIX) or <library_path>/<Library Name>\sw_services (PC) as specified by the

-lp option. Here <library_path> is the directory argument to -lp option and

<Library Name> is a subdirectory under <library_path>.

c. OS’s: For OS’s, search <library_path>/<OS Name>/bsp (UNIX) or

<library_path>/<OS Name>\bsp (PC) as specified by the -lp option. Here

<library_path> is the directory argument to the -lp option and <OS Name> is a

subdirectory under <library_path>.

3. Searching the EDK install area:

a. Drivers: Search $XILINX_EDK/sw/<Library Name>/drivers (UNIX) or

%XILINX_EDK%\sw\<Library Name>\drivers (PC)

b. Libraries: Search $XILINX_EDK/sw/<Library Name>/sw_services (UNIX) and

%XILINX_EDK%\sw\<Library Name>\sw_services

c. OS’s: Search $XILINX_EDK/sw/<Library Name>/bsp (UNIX) and

%XILINX_EDK%\sw\<Library Name>\bsp
