2. Getting Started

This section highlights some of the most common resources required to use this SDK and/or its components. This SDK is made up of several components. Component details, including capabilities, features, and limitations, are found in component specific documentation. The links to component specific documentation are indexed on the following page: SDK Components

This SDK supports J7200 family of SoCs including devices listed below.

Platform

Device

J7200

DRA821

2.1. Dependencies

This SDK and its components are built for the family of SoC specified above. Some of the demo/example/reference applications provided by SDK, depends on specific board(s), below listed are the boards/hardware dependencies

2.1.1. Hardware Dependencies

2.1.1.1. Evaluation Module (EVM)

2.1.1.2. JTAG

  • The common processor board listed above provides on on-board XDS110 USB debugger as shown here

  • Alternately an external debugger such as XDS560V2 could be used.

  • JTAG would allow one to debug execution on different compute cores, load and run applications, etc…

  • To be able to load a program via JTAG, the board will have to be configured in No Boot Mode .

  • Note that while configuring to no-boot mode is mandatory to load and run apps from CCS. It’s not mandatory, once the device is booted.

    e.g. When set to operate in mmc/sd boot mode and mmc/sd card include valid images, on powerup/boot completion, JTAG could be be used to connect to enabled compute core.

2.1.1.3. uart terminal

  • Most of the example application provided in the SDK, prints status of the application via the uart terminal.

  • Recommend to connect an serial cable to the uart terminal Debug UART of the EVM

2.1.2. Software Dependencies (not included in SDK)

2.1.2.1. Code Composer Studio (CCS) - Recommend IDE

CCS is an integrated development environment (IDE) that supports TI’s Microcontroller and Embedded Processors portfolio. Refer to CCS Setup for J7200 for steps to install and configure CCS to work with this SDK.

2.2. Demo Applications

The SDK and its components provide multiple applications that demonstrate some of the features of the SoC.

2.2.1. Build Demos from Source

In order to build and run as-is, modify, or create custom demos, then you will need to at least download the PROCESSOR SDK RTOS source package. The following sections point you in the right direction depending on if you want to build on Linux or Windows PC.

Important

Only a subset of components/demos can be built on a Windows PC, as indicated in Building on a Windows PC. If you would like to build more components not available for Windows build, then you must build on a Linux PC or Linux virtual machine.

2.2.1.1. Building on a Linux PC

  • Download and Untar the SDK tar ball ti-processor-sdk-rtos-j7200-evm-xx_xx_xx_xx.tar.gz

cd {path/to/file}
tar xf ti-processor-sdk-rtos-j7200-evm-xx_xx_xx_xx.tar.gz
  • Different components in the SDK have different demos. Please refer to the below table to get started with which demo domain you are interested in.

2.2.1.2. Building on a Windows PC

The following table specifies the components which support and do not support building on Windows PC as of this release:

Supports Windows

Does NOT support Windows

mcusw

pdk

ethfw

remote_device

In order to build supported components on Windows PC, please follow the setup sequence below:

  • Download and Untar the SDK tar ball ti-processor-sdk-rtos-j7200-evm-xx_xx_xx_xx.tar.gz

  • Download and Untar the Windows code gen tools tar ball ti-processor-sdk-rtos-j7200-evm-xx_xx_xx_xx-windows_codegen_tools.tar.gz

  • Delete the following components in the SDK tar ball and replace with the corresponding components in the windows installation

    • ti-cgt-armllvm_<version>.LTS

  • Different components in the SDK have different demos. Please refer to the below table to get started with which demo domain you are interested in.
