To flash any STM32 microcontroller from eclipse using ST-Link/V2 programing adapter and the tool “STM32 ST-LINK utility” set up an external tool as follows:

• Open “External tools Configurations”
• Double click on “Program”
• Point Location to “ST-Link_CLI.exe” path (usually c:program filesSTMicro…)
• Enter as Working Directory: ${workspace_loc:/PATH-TO-FIRMWARE-OUTPUT-FOLDER} (e.g. ${workspace_loc:/debug})
• Enter at Arguments: “-C SWD UR -Q -P “YOUR-FIRMWARE.hex” -Rst -Run”

This programs your STM32 microcontroller with the “YOUR-FIRMWARE.hex” file, resets it und runs the firmware.
