How to install customized RZ/V Linux into AI Navigator

Overview

This document explains how to install the customized Linux for your own board into AI Navigator.
This document allows users to use AI Navigator to develop the RZ/V AI Applications which runs on your own board for RZ/V device.

Terminologies

This section explains the some terminologies and background knowledges.

RZ/V AI SDK and RZ/V Linux

AI Software Development Kit (AI SDK) is an AI Application development environment for Evaluation Board Kit of RZ/V series.
AI SDK contains the RZ/V Linux with bootloader, Linux Kernel, Cross Compiler and a complete set of libraries for DRP-AI and graphics.
Users can develop AI Applications easily and quickly with AI SDK.
For details of AI SDK, please see the RZ/V AI SDK Overviewpage.

RZ/V Linux Customization

AI SDK is specifically made for RZ/V Evaluation Board Kit and AI Applications with fixed Linux components for RZ/V evaluation purpose only.
Meanwhile, AI SDK Source Code is available to customize RZ/V Linux according to your own application and your own board.

Regarding how to get the AI SDK Source Code and how to build it, please see the following pages according to the device equipped your own board.

• How to build RZ/V2L AI SDK Source Code
  
• How to build RZ/V2H AI SDK Source Code
  
  

How to install customized Linux into AI Navigator

AI Navigator can install not only AI SDK for evaluation purpose, but also the customized Linux for your own application and your own board.
However, to install your customized Linux into AI Navigator, you should follow the some procedures and requirements in this chapter.

AI SDK installation on AI Navigator

You can install the AI SDK for evaluation purpose into AI Navigator by three steps.

1. Click the “Download” button on AI Navigator to download AI SDK zip file.
   
2. Extract the downloaded AI SDK zip file to any directory.
   
3. Specify the top directory of the extracted AI SDK directory on AI Navigator file dialog.
   
   

RZ/V AI SDK File Contents

You can see the summary of the extracted AI SDK file contents in the RZ/V AI SDK Overview - File Contents pages.

How to install customized Linux into AI Navigator

You can install your customized Linux with only 1 additional step: replacing the default Linux components in the extracted AI SDK directory with your customized Linux.

1. [same step] Click the “Download” button on AI Navigator to download AI SDK zip file.
   
2. [same step] Extract the downloaded AI SDK zip file to any directory.
   2.1. [Additional step] Replace the: “Bootloader”, “Linux Kernel Files”, “Root file System” and “Cross Compiler” in the extracted AI SDK directory with your customized ones.
   
3. [same step] Specify the top directory of the extracted AI SDK directory on AI Navigator file dialog.
   
   The actual file names depend on the RZ/V device group. You can check the file names in the following pages, at the end of the step3.

Requirements to install customized Linux into AI Navigator

AI Navigator does NOT install EVERY customized Linux.
The customized Linux follows the following specifications for installation on AI Navigator.

Common requirements for customized Linux of any RZ/V device series

• AI Applications, which can be imported by AI Navigator, expect that the RZ/V Linux includes the components listed in the following pages.
  If you use AI Applications on your own board, please DON’T remove the listed components.
  • RZ/V2L AI SDK Specification
    
  • RZ/V2H AI SDK Specification
    
• DRP-AI TVM, which is included in AI SDK, works with only the version of GCC toolchain included the default Linux components in AI SDK. Please DON’T remove the GCC toolchain, and change the version of it.
  • For details of DRP-AI TVM, please see the Renesas GitHub for DRP-AI TVM.
    

Specific requirements for RZ/V2L customized Linux

• AI Navigator supports only the eSD boot only when debugging AI applications. Please build the eSD bootloader and use it.
  

Specific requirements for RZ/V2H customized Linux

• No specific requirements.
