JSON description

The commands for Run config command are accepted through JSON file interface. These include:

• Hierarchy
• JSON File
• Command Group
• Command
• Generating extra launch configurations

Hierarchy

JSON file introduces several layers of abstractions that serve different purposes.

Abstraction	Description
JSON File	Highest level of abstraction. Depicts a superset of use-cases.
Command Group	Use-case level. Depicts a series of commands that is used to achieve one outcome.
Command	Lowest level of abstraction. Depicts a single command to execute.

JSON File

Structure

{    
    "schema-version": 1.0, 
    "content": [
        // add command groups here
    ]
}

Properties

Name	Type	Optional/Required	Description
schema-version	number	required	Version of syntax used in JSON file.
content	list	required	List of command group objects.

Command Group

Structure

{
    "name": "Command Group Name",               // Command Group name
    "description": "Command Group Description", // Command Group description
    "enabled": true,                            // Enable or Disable this Command Group
    "commands": [
        // add commands here
    ]
}

Properties

Name	Type	Optional/Required	Description
name	string	required	Command Group name. Used for readability and debugging purposes.
description	string	optional	Command Group description. Used for readability purposes only.
enabled	boolean	optional	Enabling Command Group can be enabled or disabled. Disabled command group will not be executed. Default: false.
commands	list	required	List of command objects.

Command

Structure

{
    "command": "extract-payload",                // Command name
    "inputs": [                                  // Command inputs
        {
            "description": "Input description",

            "file": "output.bin"
        }
    ]
}

Properties

Name	Type	Optional/Required	Description
command	string	required	Command name. Available values: add-signature, custom-script, extract-payload, hex-segment, merge, shift and sign.
inputs	list	required	Command inputs. Different commands may have different requirements for this field.
outputs	list	optional	Command outputs. Different commands may have different requirements for this field.

Generating extra launch configurations

When you create a new ModusToolbox™ project, it contains set of common launch configurations. When customizing output hex files, you may need to generate additional Eclipse or VS Code Debug launch configurations for the specific hex files. To do this, insert a special "extra_config" section into the json file. Then, regenerate the launch configurations. For Eclipse, click the "Generate Launches for ..." link in the Quick Panel, or run "make eclipse" in a bash terminal (modus-shell for Windows). For VS Code, run "make vscode".

Extra_config properties

Name	Type	Optional / Required	Description
project	string	required	Project name that requires debugging. (This is used to determine the main elf file. The debug session will start from the beginning of main() defined in this elf). The launch config will be bound to this project.
debug_config_name	string	required	Specifies the output launch config name in the form [debug_config_name] Debug [probe].
build_dependency	string	optional	Specifies whether the generated launch config should build a particular project or the entire application. Default is "project". Valid values are "project" or "application".
default	boolean	optional	If set to true, this hex file will be used for make program and the Program Application config. Default is "false".
extra_elf_path	string	optional	Allows you to set additional elf file(s) to be used for debugging. It requires the path to the extra elf file relative to the Application-level directory. Supported for TrustZone-enabled devices.
