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.

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)¶
This SDK is intended to run on the following board combination:
For details on configuring the EVM to run this SDK, refer to the EVM Setup for J7200 section.
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.

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.
