Installation on NVIDIA DRIVE OS QNX

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

Note

If flashing NVIDIA DRIVE OS via NVIDIA SDK Manager fails, unset QNX_BASE and retry again with NVIDIA SDK Manager. As an alternative, remove QNX_BASE from ~/.bashrc and retry again with NVIDIA SDK Manager.

To Install the NVIDIA DriveWorks SDK on a Platform That Has NVIDIA DRIVE OS QNX Installed

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 filesystem that the NVIDIA DriveWorks SDK 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-4.0/targets/aarch64-QNX/lib:/mnt/usr/local/driveworks-4.0/bin
   $ export LD_LIBRARY_PATH=${CUDA}:${DRIVEWORKS}:${GRAPHICS_ROOT}:${BASE_LD_LIBRARY_PATH}

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

   $ mkdir -p /tmp/driveworks-4.0-qnx-filesystem
   $ cd /tmp/driveworks-4.0-qnx-filesystem
   $ tar -xf driveworks-v4.0.0_*_drive-qnx-5.2.6.0.tar.gz
   $ tar -xf driveworks_samples-v4.0.0_*_drive-qnx-5.2.6.0.tar.gz
   $ tar -xf driveworks_data-v4.0.0_*_drive-qnx-5.2.6.0.tar.gz

5. Copy all the NVIDIA DriveWorks SDK files to the NVIDIA DRIVE platform.

   On the host system, execute:

   $ scp -rp /tmp/driveworks-4.0-qnx-filesystem root@ip_address:/mnt

   where /tmp/driveworks-4.0-qnx-filesystem is the folder into which the NVIDIA DriveWorks SDK QNX archives have been decompressed.
