Using the code example

Following are the bootloader examples, containing standalone Edge Protect Bootloader. This example does not bundle a user application with it. You need to integrate the bootloader with other code examples, such as PSOC_Edge_Basic_Secure_App.

The default configuration provided serves as a foundational example, demonstrating the initial steps to implement a basic Edge Protect Bootloader alongside with a code example or applications. This starting point is designed to be straightforward, allowing you to become acquainted with the fundamental operations and interactions between the bootloader and the application.

Following code examples are pre-configured to work with Edge Protect Bootloader out of the box.

Code example	Description
PSOC™ Edge Basic Secure App	For getting started with Edge Protect Bootloader with a simple use case
PSOC™ Edge SRAM loading	For loading applications from external flash to SRAM for execution
PSOC™ Edge MCU OTW update	For performing firmware using wired interfaces
PSOC™ Edge MCU encryption	For Encrypted boot demonstration with Edge Protect Bootloader

You will need create these applications, add the bootloader, build, and program them independently for different use cases as instructed below. The default code configuration demonstrates how to start with PSOC_Edge_Protect_Bootloader and PSOC_Edge_Basic_Secure_App. Once you are familiar with this basic use cases, you can explore more advanced features such as secured boot, testing secured update, and moving the Edge Protect Bootloader (PSOC_Edge_Protect_Bootloader) to the external flash, etc.

Create PSOC_Edge_Protect_Bootloader application

The ModusToolbox™ tools package provides the Project Creator as both a GUI tool and a command line tool.

Use Project Creator GUI

Open the Project Creator GUI tool

There are several ways to do this, including launching it from the dashboard or from inside the Eclipse IDE. For more details, see the Project Creator user guide (locally available at {ModusToolbox™ install directory}/tools_{version}/project-creator/docs/project-creator.pdf)
On the Choose Board Support Package (BSP) page, select a kit supported by this code example. See Supported kits

Note: To use this code example for a kit not listed here, you may need to update the source files. If the kit does not have the required resources, the application may not work
On the Select Application page:

a. Select the Applications(s) Root Path and the Target IDE

Note: Depending on how you open the Project Creator tool, these fields may be pre-selected for you

b. Select this code example from the list by enabling its check box

Note: You can narrow the list of displayed examples by typing in the filter box

c. (Optional) Change the suggested New Application Name and New BSP Name

d. Click Create to complete the application creation process

Use Project Creator CLI

The 'project-creator-cli' tool can be used to create applications from a CLI terminal or from within batch files or shell scripts. This tool is available in the {ModusToolbox™ install directory}/tools_{version}/project-creator/ directory.

Use a CLI terminal to invoke the 'project-creator-cli' tool. On Windows, use the command-line 'modus-shell' program provided in the ModusToolbox™ installation instead of a standard Windows command-line application. This shell provides access to all ModusToolbox™ tools. You can access it by typing "modus-shell" in the search box in the Windows menu. In Linux and macOS, you can use any terminal application.

The following example clones the "Edge Protect Bootloader" application with the desired name "EdgeProtectBootloader" configured for the KIT_PSE84_EVAL_EPC2 BSP into the specified working directory, C:/mtb_projects. The directory C:/mtb_projects has to be created manually before calling the command:

project-creator-cli --board-id KIT_PSE84_EVAL_EPC2 --app-id mtb-example-edge-protect-bootloader --user-app-name EdgeProtectBootloader --use-modus-shell --target-dir "C:/mtb_projects"

The 'project-creator-cli' tool has the following arguments:

Argument	Description	Required/optional
`--board-id`	Defined in the field of the BSP manifest	Required
`--app-id`	Defined in the field of the CE manifest	Required
`--target-dir`	Specify the directory in which the application is to be created if you prefer not to use the default current working directory	Optional
`--user-app-name`	Specify the name of the application if you prefer to have a name other than the example's default name	Optional

Note: The project-creator-cli tool uses the git clone and make getlibs commands to fetch the repository and import the required libraries. For details, see the "Project creator tools" section of the ModusToolbox™ tools package user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mtb_user_guide.pdf).

Open Edge Protect Bootloader application

After the project has been created, you can open it in your preferred development environment.

Eclipse IDE

If you opened the Project Creator tool from the included Eclipse IDE, the project will open in Eclipse automatically.

For more details, see the Eclipse IDE for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_ide_user_guide.pdf).

Visual Studio (VS) Code

Launch VS Code manually, and then open the generated {project-name}.code-workspace file located in the project directory.

For more details, see the Visual Studio Code for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_vscode_user_guide.pdf).

Arm® Keil® µVision®

Double-click the generated {project-name}.cprj file to launch the Keil® µVision® IDE.

For more details, see the Arm® Keil® µVision® for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_uvision_user_guide.pdf).

IAR Embedded Workbench

Open IAR Embedded Workbench manually, and create a new project. Then select the generated {project-name}.ipcf file located in the project directory.

For more details, see the IAR Embedded Workbench for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_iar_user_guide.pdf).

Command line

If you prefer to use the CLI, open the appropriate terminal, and navigate to the project directory. On Windows, use the command-line 'modus-shell' program; on Linux and macOS, you can use any terminal application. From there, you can run various make commands.

For more details, see the ModusToolbox™ tools package user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mtb_user_guide.pdf).
