MBEDLS

NAME

mbedls - detect and list Mbed Enabled devices connected to the host computer

SYNOPSIS

mbedls [--simple|--json] [--debug]

mbedls --list

mbedls --mock ID:NAME

mbedls --help

mbedls --version

DESCRIPTION

mbedls detects and lists ARM Mbed Enabled devices connected to the host computer.

It provides the following information for all connected boards in a console (terminal) output:

	•		Mbed OS platform name
	•		mount point (MSD or disk)
	•		serial port

mbedls requires that an Mbed device be mounted before it shows up in the results. Many systems do not automatically mount USB devices. It is recommended that you use an automounter to manage this for you.

OPTIONS

-s, --simple

list attached targets without column headers and borders

-j, --json

list attached targets with detailed information in JSON format

-J, --json-by-target-id

map attached targets from their target ID to their detailed information in JSON format

-p, --json-platforms

list attached platform names in JSON format

-P, --json-platforms-ext

map attached platform names to the number of attached boards in JSON format

-l, --list

list all target IDs and their corresponding platform names understood by mbedls

-m, --mock ID:NAME

substitute or create a target ID to platform name mapping used when invoking mbedls in the current directory

--skip-retarget

skip parsing and interpretation of the re-target file, ./mbedls.json

-u, --list-unmounted

list mbeds, regardless of whether they are mounted or not

-d, --debug

outputs extra debug information useful when creating issues!

--help

print usage details and exit

--version

print package version and exit

RESULT FORMATS

The mbedls command-line accepts a few arguments to change the format of the results. The default format is a table. You may pass --simple to simplify this table format, and --json to print the table as a JSON list of the rows.

MOCKING (RENAMING) PLATFORMS

Override a platform’s name using the --mock parameter:

$ mbedls --mock 0240:MY_NEW_PLATFORM
$ mbedls
+-----------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| platform_name | platform_name_unique | mount_point | serial_port | target_id | daplink_version |
+-----------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| MY_NEW_PLATFORM | MY_NEW_PLATFORM[0] | D: | COM18 | 0240000032044e4500257009997b00386781000097969900 | 0244 |
+-----------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+

The --mock parameter accepts a platform ID and a platform name, separated by the : character. The platform ID is the first 4 characters of the target_id. The platform name is the name you are temporarily assigning to this platform.

To remove a mocked platform, use the --mock parameter again. Continuing from the previous example, use -<platform id> as the value:

$ mbedls --mock -0240
$ mbedls
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| platform_name | platform_name_unique | mount_point | serial_port | target_id | daplink_version |
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| K64F | K64F[0] | D: | COM18 | 0240000032044e4500257009997b00386781000097969900 | 0244 |
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+

You can also remove all mocked platforms by supplying * as the target_id:

$ mbedls --mock="-*"

NOTE: Due to a quirk in the parameter formatting, the command-line can interpret -* as another parameter instead of a value. It is necessary to use the complete --mock="-*" syntax, so the command-line interprets each part of the command correctly.

RETARGETTING PLATFORMS

It is possible to change the returned results for certain platforms depending on the current directory. This is especially useful when developing new platforms.

The command-line tool and Python API check the current directory for a file named mbedls.json. When it is present, it overrides the returned values. The format of the mbedls.json file is:

{
"<target_id>": {
"<key>": "<value>"
}
}

For example, to change the serial_port of the K64F with a target_id of 0240000032044e4500257009997b00386781000097969900, the mbedls.json file contains the following:

{
"0240000032044e4500257009997b00386781000097969900": {
"serial_port": "COM99"
}
}

This results in the following output from the command-line tool:

$ mbedls
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| platform_name | platform_name_unique | mount_point | serial_port | target_id | daplink_version |
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+
| K64F | K64F[0] | D: | COM99 | 0240000032044e4500257009997b00386781000097969900 | 0244 |
+---------------+----------------------+-------------+-------------+--------------------------------------------------+-----------------+

Note how the serial_port value changed from COM18 to COM99. Deleting the mbedls.json or using the --skip-retarget parameter removes these changes.
