Altera RTE for OpenCL Instrukcja Użytkownika Pobierz pdf (Strona 45)

Create an RTE directory on the board's file system by typing the mkdir <rte_destina-

tion_directory> command.

Move the downloaded installation package aclrte-arm32.tgz to the RTE directory by typing the mv

aclrte-arm32.tgz <rte_destination_directory> command.

Type cd <rte_destination_directory> to navigate to the RTE directory.

To unpack the tarball, type tar -xvfz aclrte-arm32.tgz at the command prompt.

5. Transfer the aclsoc_drv.ko file you built on your development machine into the <rte_destina‐

tion_directory>/board/c5soc/driver directory on the SoC board.

6. Set the environment variables, as shown below.

Altera recommends that you consolidate the settings of the environment variables into a file called init_

opencl.sh. Then, run the command source ./init_opencl.sh to load all the environment

variables and the OpenCL Linux kernel driver simultaneously.

export ALTERAOCLSDKROOT=<rte_destination_directory>

export AOCL_BOARD_PACKAGE_ROOT=$ALTERAOCLSDKROOT/board/c5soc

export PATH=$ALTERAOCLSDKROOT/bin:$PATH

export LD_LIBRARY_PATH=$ALTERAOCLSDKROOT/host/arm32/lib:$LD_LIBRARY_PATH

insmod $AOCL_BOARD_PACKAGE_ROOT/driver/aclsoc_drv.ko
