Standalone Executable

Edge Protect Tools can be used as a standalone application. The executable can be found in the tools/edgeprotecttools/bin directory of the Edge Protect Security Suite or Early Access Pack installation.

Installing From Sources

Alternatively Edge Protect Tools can be installed from the sources as a Python package. The source code is located in the tools/edgeprotecttools/src directory of the Edge Protect Security Suite or Early Access Pack installation.

Install Python 3.12 on your computer. You can download it from https://www.python.org/downloads/. Set up the appropriate environment variable(s) for your operating system.

Installing Package

Make sure that you have the latest version of pip installed, use the following command.

$ python -m pip install --upgrade pip

Run the following command, from the Early Access Pack or Edge Protect Security Suite directory.

$ python -m pip install tools/edgeprotecttools/src

Updating Package

To update the already installed package, run the following command from the Early Access Pack or Edge Protect Security Suite directory.

$ python -m pip install --upgrade --force-reinstall tools/edgeprotecttools/src

Note: There may be some pip dependency resolver errors. In most cases, these can be safely ignored.

Note: You can use the following command to show the path to the installed package $ python -m pip show edgeprotecttools.

Supported Devices

Use device-list command for output of the supported devices list.

$ edgeprotecttools device-list

Interface and Usage

For instructions how to use common commands, see README_GENERAL.md.

For instructions how to use target-specific commands, see the corresponding readme file in the docs directory.

Logging

Every time the tool is invoked, a new log file is created in the logs directory of the project. By default, the console output has INFO logging severity. The log file contains the DEBUG logging severity.

Known Issues

• Using the policy from CySecureTools 4.0.0 in projects created by CySecureTools 4.1.0 causes the CY_FB_INVALID_IMG_JWT_SIGNATURE error during re-provisioning on PSoC64-2M devices:

  ...
  ERROR : SFB status: CY_FB_INVALID_IMG_JWT_SIGNATURE: Invalid image certificate signature. Check the log for details

Workaround:

1. Open the policy file.
2. Navigate to section 1 of the boot_upgrade/firmware.
3. Set boot_auth and bootloader_keys as follows:

"boot_auth": [
    3
],
"bootloader_keys": [
    {
        "kid": 3,
        "key": "../keys/cy_pub_key.json"
    }
]

• During the installation of the package via pip on Mac OS Big Sur, the following exception is raised:

  ...
  distutils.errors.DistutilsError: Setup script exited with error: SandboxViolation:
  mkdir('/private/var/root/Library/Caches/com.apple.python/private/tmp/easy_install-y8c1npmz', 511) {}

  The package setup script has attempted to modify files on your system
  that are not within the EasyInstall build area, and has been aborted.

  This package cannot be safely installed by EasyInstall, and may not
  support alternate installation locations even if you run its setup
  script by hand.  Please inform the package's author and the EasyInstall
  maintainers to find out if a fix or workaround is available.

Solution: Upgrade the pip package running the following command from the terminal: python3 -m pip install --upgrade pip.
