Installation on NVIDIA DRIVE Platform (QNX)

These instructions install NVIDIA^® DriveWorks on an NVIDIA DRIVE platform on which NVIDIA DRIVE QNX is already installed.

To install NVIDIA DriveWorks on a platform that has DRIVE QNX

1. On the platform, format a power-safe filesystem

    $ mkqnx6fs /dev/vblk_mnand2
   

   Note

   After flashing the platform, this step is performed only once.

2. On the platform, mount the file system that NVIDIA DriveWorks uses.

    $ mount  /dev/vblk_mnand2 /mnt
   

   Note

   This step must be executed after every reboot.

3. On the platform, export the following environment variables:

    $ export BASE_LD_LIBRARY_PATH=/usr/libnvidia:/lib:/lib/dll:/usr/lib
    $ export PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin
    $ export GRAPHICS_ROOT=/usr/libnvidia/screen
    $ export CUDA=/usr/local/cuda/lib:/usr/local/cuda/lib/stubs
    $ export DRIVEWORKS=/mnt/usr/local/driveworks-<version>/targets/aarch64-QNX/lib
    $ export LD_LIBRARY_PATH=${CUDA}:${DRIVEWORKS}:${GRAPHICS_ROOT}:${BASE_LD_LIBRARY_PATH}
   

   Note

   When installing from the official archives, /path/to/driveworks-M.m/ is /mnt/usr/local/driveworks-M.m/

4. On the host Linux system (x86 machine), extract all packages:

    $ tar xvf driveworks-<vsn_and_rel_info>-drive-qnx-<pdk-version>.tar.gz
    $ tar xvf driveworks_data-<vsn_and_rel_info>-drive-qnx-<pdk-version>.tar.gz
    $ tar xvf driveworks_samples-<vsn_and_rel_info>-drive-qnx-<pdk-version>.tar.gz
   

5. Copy all NVIDIA DriveWorks files to the NVIDIA DRIVE platform. On the host system, execute:

    $ scp -rp <driveworks_folder> root@ip_address:/mnt
   

   Where <driveworks_folder> is the folder into which the QNX archives have been decompressed.
