Documentation

mbed-flasher

Description

mbed-flasher is a simple Python-based tool for flashing single or multiple boards. It provides a simple Command Line Interface and Python API for flashing.

The purpose is to provide a clean and simple library that is easy to integrate to other tools. It can be easily developed further to support flashing in mbed OS and other platforms. Developers can also use it as a standalone tool for flashing their development boards.

Installation

To install the flasher, use:

python setup.py install

To install the flasher in development mode:

python setup.py develop

To use JLink flashing, additional package needs to be installed from here. JLinkExe must be found from PATH for flasher to be able to use it.

To use STLink flashing (windows only), additional package needs to be installed from here. ST-LINK_CLI.exe must be found from PATH for flasher to be able to use it.

Usage

This tool has been tested and verified to work with Windows 7 and Ubuntu (14.04 LTS) Linux.

Devices used in verification: NXP K64F, Nucleo F401RE, BBC micro:bit.

Flash help

/>mbedflash flash --help
usage: mbedflash flash [-h] [-i INPUT] [--tid TARGET_ID] [-t PLATFORM_NAME]
                       [--no-reset]
                       [method]

positional arguments:
  method                <simple|pyocd|edbg>, used for flashing

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT, --input INPUT
                        Binary input to be flashed.
  --tid TARGET_ID, --target_id TARGET_ID
                        Target to be flashed, ALL will flash all connected
                        devices with given platform-name, also multiple
                        targets can be given. Does not continue flashing
                        next device in case of failures. Short target_id
                        matches boards by prefix
  --target_filename TARGET_FILENAME
                        Custom target filename
  -t PLATFORM_NAME, --platform_name PLATFORM_NAME
                        Platform of the target device(s)
  --no-reset            Do not reset device before or after flashing

--target_filename TARGET_FILENAME -option is used to select custom target filename when source file is copied to mbed target

e.g.

$ mbedflash flash simple --tid 0240000032254e45000f800ab529001f3f31000097969900 -i setup.hex --target_filename asd.hex

input file in above example would be setup.hex, that must exists and filename that is created for target mount point would be asd.hex.

Erase help

c:\>mbedflash erase --help
usage: mbedflash erase [-h] [--tid TARGET_ID] [method]

positional arguments:
  method                <simple|pyocd|edbg>, used for erase

optional arguments:
  -h, --help            show this help message and exit
  --tid TARGET_ID, --target_id TARGET_ID
                        Target to be erased or ALL, also multiple targets can
                        be given. Short target_id matches boards by prefix

Reset help

c:\>mbedflash reset --help
usage: mbedflash reset [-h] [--tid TARGET_ID] [method]

positional arguments:
  method                <simple|pyocd|edbg>, used for reset

optional arguments:
  -h, --help            show this help message and exit
  --tid TARGET_ID, --target_id TARGET_ID
                        Target to be reset or ALL, also multiple targets can
                        be given. Short target_id matches boards by prefix
