setupCodegenContext

Select the target hardware to build code for from multiple live connection objects

Add-On Required: This feature requires the MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms add-on.

Syntax

setupCodegenContext(hwObj)

Description

setupCodegenContext(hwObj) selects the NVIDIA^® target hardware to generate code for. When there are multiple live connection objects for different targets, the code generator performs remote build on the target for which a recent live object was created. To choose a hardware board for performing remote build, use the setupCodegenContext() method of the respective live hardware object. If only one live connection object was created, you need not call this method.

Examples

Select the Target from Multiple Live Connection Objects

This example shows how to use the setupCodegenContext() method and select the NVIDIA Jetson™ board for code generation when the MATLAB^® session has multiple live connection objects.

Create a connection, hwJetson, from the MATLAB software to NVIDIA Jetson hardware.

hwJetson = jetson

To choose a hardware board for performing remote build, use the setupCodegenContext() method of the respective live hardware object.

setupCodegenContext(hwJetson);

The code generator now performs code generation for the Jetson hardware target.

Input Arguments
