Prepare SD Card for Boot

We recommend that you use an SD card populated with the RTOS BSP secondary bootloader (SBL) so that the phyCORE-AM572x RDK hardware is configured (pinmux, clocks, etc.) by the RTOS board support library.

...

cd $RTOS_INSTALL_ROOT/pdk_am57xx_1_0_8/packages

# set up the environment for building the diagnostic applications
source pdksetupenv.sh

cd $RTOS_INSTALL_ROOT/pdk_am57xx_1_0_8/packages/ti/board/diag
make am572x_phycore_rdk_sd
cd $RTOS_INSTALL_ROOT/pdk_am57xx_1_0_8/packagis/ti/board/bin/am572x_phycore_rdk/sd

# In the following command, replace <user> with your host's username
cp * /media/<user>/boot/
sync

CreateSimpleCCSProject CreateSimpleCCSProject

Create a Simple Code Composer Studio Project

You will now create a simple CCS project to test your JTAG connection to the phyCORE-AM572x RDK.

...

1. Set Target to AM572x - Cortex A15 and the secondary Target field to AM572X_PHYCORE_RDK.

   Note
   If AM572X_PHYCORE_RDK isn't a selectable option in the secondary Target field, it is likely that the am572x_phycore_rdk.xml file was not correctly installed in the Install CCS Configuration Files step. Please review this step and try again after restarting CCS.

   
   

2. Set Connection to Texas Instruments XDS2xx USB Debug Probe.
3. Click the Cortex A [ARM] tab and set your project name to hello_world.
4. Under Advanced Settings, set Linker command file to AM572x.lds.
5. Under Project templates and examples, select Hello World from the Basic Examples section.
   Your New CCS Project window should now look similar to this screenshot:
   
6. Click Finish.

Build and Debug the Simple Code Composer Studio Project

Building and debugging this simple CCS project is a relatively easy process. Follow these steps to ensure your build environment is set up correctly and that you are able to debug your project through the JTAG interface.

...

1. Ensure that you have a target configuration file in your project set to Active/Default. If you followed the steps in the Create a Simple Code Composer Studio Project section, this file (AM572X_PHYCORE_RDK.ccxml by default) and setting will be created for you.

   To create a target configuration file manually, right click the hello_world project name in the Project Explorer window and click New → Target Configuration File. Select AM572X_PHYCORE_RDK in the Board or Device list and click Save under Save Configuration.

   Warning

   Due to a bug in the Sitara Device Support package installed with the recommended version of CCS, you will likely need to modify the target configuration file before your project will build. To do so, open the target configuration file (AM572X_PHYCORE_RDK.ccxml by default) from your Project Explorer window. Click the Advanced tab at the bottom of the Target Configuration window. Note that the third and fourth ICECrusherCS entries have duplicate names. Rename the third ICECrusherCS entry to ICECrusherCS_2 and the fourth ICECrusherCS entry to ICECrusherCS_3 and save the target configuration.

2. Open your project's target configuration file from the Project Explorer window.

...

1. If all of the previous steps have been followed correctly, the hello_world program will be paused at an automatically generated breakpoint at line 7 of hello.c. Click the Resume button located in the top toolbar.
2. You should see "[CortexA15_0] Hello World!" in the Console window just like this screenshot:
   
   

Generate Example Code Composer Studio Projects

...

Included with this RTOS BSP is a number of configuration files that can be used to generate importable CCS projects for reference and interface testing. This section will explain how to generate and import these CCS projects.

Generate Example Projects

The Platform Development Kit (PDK) provides a script to search through the PDK and generate importable CCS projects if it finds configuration files that match the arguments given to the script. Run these commands to generate these projects:

...

Within your current directory you should now have a new subdirectory called MyExampleProjects that contains an additional subdirectory for each found configuration file that matches the arguments given to the pdkProjectCreate.sh script.

Import and Configure Example Projects

To import the example projects, start by opening CCS.

...

Your imported project should now be ready to build and debug.

Build the RTOS BSP from Source

...

This section will explain how to download and build from the RTOS BSP sources. Please note that this is not a required procedure but the steps and scripts to build the BSP from source are offered here for reference.

Configure Bash as Default Shell

By default, Ubuntu 16.04 uses the Debian Almquist Shell (dash) for calls to the Bourne Shell (sh). This will cause issues in building certain RTOS BSP components as some of Dash's built-in commands do not support all of the required options. To ensure your system uses Bash over Dash for calls to /bin/sh, run this command:

...

Select <No> when prompted to use dash as the default system shell (/bin/sh).

Install Additional Host Debian Packages

Building the RTOS BSP from source requires additional packages to be installed. Run the following command to ensure you have the packages installed:

...

Install the Linaro Toolchain

Run the following commands to install the Linaro Toolchain:

...

Install the Repo Tool

The repo tool is used to obtain RTOS BSP sources from Git. Run the following commands to install the repo tool:

...

Git Setup

If you have not yet configured your Git environment on this machine, please run the following commands to set your user name and email address. See here for more information on getting started with Git.

git config --global user.email "your@email.com"
git config --global user.name "Your Name"
git config --global http.sslcainfo /etc/ssl/certs/ca-certificates.crt

Create a Build Directory

A separate directory from the standard install directory is required to build the RTOS BSP from source. Run these commands:

...

Download the BSP Sources

Download the manifest file for the AM57x RTOS PD17.1.0 x BSP:

cd $RTOS_BUILD_ROOT
repo init -u https://stash.phytec.com/scm/tirtos/manifests-phytec.git -b am57x -m BSP-RTOS-TI-AM57x-PD17.1.01.xml

Download the RTOS BSP sources specified in the manifest file:

repo sync

Start the Build and Install

The RTOS build and install script will download and install components not offered through Git as well as build and install components sourced through the above manifest. Run the following commands to start the build:

...

Rebuild the Platform Development Kit After Modification

...

The Platform Development Kit (PDK) contains the majority of the board and hardware-specific drivers and libraries and, when modified, will need to be rebuilt before use. This section will explain how to rebuild the PDK component of the RTOS BSP.

...
