NVIDIA DRIVE Directory
CUDA Directory
After installation, these directories are created:
• The NVIDIA DRIVE™ directory, ./drive‑t186ref‑linux
• The CUDA directory, ./ drive-t186ref-cuda
• The toolchains directory, ./toolchains
• The foundation directory, ./drive-t186ref‑foundation
• The hardware-specific directory, ./hardware (PDK only)
This topic describes the contents of the NVIDIA DRIVE™ directory and the CUDA directory. The toolchains directory and the foundation directory are part of NVIDIA DRIVE™ Foundation 5.1 SDK, and are described in the NVIDIA DRIVE™ Foundation SDK Development Guide.
For information on installing, see Installing the SDK on Linux.
