This guide is included in the EVM kit and also available for download from the software download page for your particular device. This is a good landing page to bookmark since all links below can be found in the Developer Guide.

This is only required one time. After that, you can use Windows to delete the SD card contents and replace it with whatever you would like to boot. To save installer space, this file is compressed. Once uncompressed, the file name will be boot.

Download a disk imager program to write the image file to the SD card. The open source Win32 Disk Imager is a good option. The utility is designed to update the SD card volume information to match the size of the image copied to its volume.

This can result in large portion of the volume being unused on the SD cards. You can restore the volume on the SD card using linux based SD formatting utilities. This utility formats the SD cards in a way by which it retains the original size and also in a format recognized by the ROM bootloader. This method works with all the platforms. However, this method requires the PDK installation on Linux and using the SD card creation script provided in the installer.

Safely eject the SD card from the computer. The script will give you information about each step, but the following sections will go over the details and walk you through how to use the script as well.

The create-sdcard. This usually means using the sudo command to start execution of the script. For example:. The SDK comes with pre-built images that can be directly loaded on an SD card without having to do any builds. The path for these files are:. If you fail to execute the script with root permissions you will receive a message that root permissions are required and the script will exit.

The first step of the script will ask you to select the drive representing the SD card that you want to format. In most cases your host root file system drive has been masked off to prevent damage to the host system. When prompted enter the device number corresponding to the SD card. For example, if the output looks like:.

For most common installations, this script works fine. However, if you are using more advanced disk slicing and volume management, the presented list of device nodes are off by one; in the best case picking the last item it will flag a range error, and in the worst case anything in the middle the wrong DASD can be destroyed. Any partitions of the device that are already mounted will be un-mounted so that the device is ready for partitioning.

The purpose of this section is to cover how to use the create-sdcard. These components are all installed in one common install path specified when running the installer. This directory contains the following top-level directories and files; here is an example for AM57x:.

See Release Notes for applicable components for a specific platform. The package provides well-defined API abstraction layers allowing applications to quickly utilize different peripherals accessible from an SOC.

Certain features are platform dependent and are clarified in the associated User Guides. The Processor SDK comes with pre-built libraries for everything you need to start writing an application.

However, you may want to customize and rebuild from source. For components not covered by this top-level Makefile, please see guides within the respective component for build instructions. The warnings of optional parameters not configured can be ignored since we are only rebuilding the libraries and not generating a release package.

Please rebuild individual components in the PDK package for these devices to avoid long build times. You can find the list of all the targets by invoking help target as described above. Depending on the capabilities and software available for a given device additional targets may also be defined:.

The following examples demonstrate how to use the top-level Makefile for some common tasks. All of the examples below assume that you are calling the Makefile from the top-level of the SDK.

Instructions for rebuilding sub-components can be found in documentation within the component. Here are a collection of useful pages:. The instructions below are for building for one platform. If you are developing for multiple platforms e. Additionally the environment PATH variable must be updated with the install location of gmake binary.

The build environemnt shall also be set running pdksetupenv script file provided within the PDK. The defaults in the Rules. For example,. Please note that parallel make -j4 is not supported within individual PDK components. PDK users can invoke the build for specific core and specific platform using the following syntax. The Rules. Please note that parallel make -j is not supported within individual PDK components.

The components PDK can be rebuilt from their git repositories. When updating PDK for picking up bug fixes or for development, please be aware that the supporting components like tools versions might have changed since the previous release. Please ensure that those are downloaded in the processor sdk installation directory.

The following steps detail how the scripts are used to create CCS project content. Project compilation and successful execution cannot be guaranteed for products not installed with the PDK.

Please refer to pdkProjectCreate. The scripts will throw errors for invalid input parameters and for invalid configurations. For example, attempting to build DSP projects for the amx device will throw an error since the amx device does not contain a DSP processor. Click on Browse and select the top level directory where the project is present.

For example. To build the project; ensure that the project you want to build, i. Naming convention of Projects created:. Technical support is a broad term. There is an active community of TIers and other customers like you already using a TI Processor, on these forums.
