Board Support Package For NVIDIA Jetson Boards
Introduction

NVIDIA Jetson Nano & Xavier Boards |
This board support package (BSP) supports NVIDIA Jetson Nano & Xavier boards. The BSP has two versions
1. Local Build version: It uses GCC ARM ARCH64 Embedded cross complier for building binaries that execute on Jetson hardware. This build version does not support NVIDIA CUDA API for building programs for on-board NVIDA GPGPU.
2. Remote Build version: This version uses CASP’s remote build capabilities to build and deploy CASP models on the NVIDIA Jetson target. It uses NVIDIA Developer Kit SDK that was pre-installed on target board. It supports CASP simulation panel (SimPanel) and supports NVIDIA CUDA API. For remote build to work, both host and target systems shall be connected through common LAN.
Getting Started
· NVIDIA Developer Kit shall be downloaded and installed on NVIDIA Jetson hardware from official NVIDIA website.
· For Local Build version of BSP, create and build model on host PC to generate required binary. The generated binary can be copied and executed by the user on Jetson hardware.
· Following steps shall be followed for Remote Build version
1. Generate Remote Build Tool chain for Jetson from CASP -> Tools -> HwTools->RemoteBuild. CASP creates a folder containing files that can run on Jetson hardware. Copy the folder to Jetson hardware and follow instructions from ‘readme_setup.txt’ file located in the root directory.
2. Run casp_rbuild from the Jetson terminal with proper IP address as argument.
3. Enter the target IP from above step in Remote Build/Deploy IP address in CASP Setup Simulation window as shown below
4. Enter/Select other setup options and click on Run to build and deploy the model on Jetson target.

Programmer
For Local Build version, user has to manually copy generated binary from project bin directory on host PC to Jetson hardware.
For Remote Build version, binary file is created and executed on target itself, when user presses Run button.
Debugging
Debugging is supported through console display for local build version and via Simulation Panel message window for remote build version.
