ST-LINK MSD Driver

jumpstarter-driver-stlink-msd flashes STM32 Nucleo and Discovery boards by copying firmware to the ST-LINK USB mass storage volume.

This is an alternative to probe-rs that avoids known connect-under-reset issues with ST-Link V3. The ST-LINK's built-in mass storage interface handles all the flash programming.

Installation

pip3 install --extra-index-url https://pkg.jumpstarter.dev/simple/ jumpstarter-driver-stlink-msd

Configuration

export:
  flasher:
    type: jumpstarter_driver_stlink_msd.driver.StlinkMsdFlasher
    config:
      # volume_name: "NOD_H755ZI"   # optional: auto-detected if only one ST-LINK is connected

Parameter	Description	Type	Required	Default
volume_name	Name of the mounted ST-LINK volume (e.g. `NOD_H755ZI`)	str \| None	no	auto-detect

Supported Formats

Format	Handling
`.bin`	Copied directly to the ST-LINK volume
`.hex`	Copied directly to the ST-LINK volume

ELF files must be converted externally before flashing:

arm-none-eabi-objcopy -O binary zephyr.elf zephyr.bin

Usage

j flasher flash firmware.bin       # flash a raw binary
j flasher flash firmware.hex       # flash an Intel HEX file
j flasher info                     # show ST-LINK volume details
