System Workbench for STM32


STLink programming/debug problem

Windows, stlink utility detects board via

VID/PID 0x0483 0x3748 for ST-Link/V2

Program, erase and checksum via GUI no problem. Selecting .bin file from a STM32 workbench built test project works.

Back to STM32 work bench. Using “install_sw4stm32_win_32bits-v1.8.exe” bundled eclipse edition.

All I get on run is:

Cannot debug or run using default scripts:
