12. Clone ST LINK C45 mode

Clone ST-LINK C45 Mode

Use launcher mode:

B - C45 / Clone ST-Link

This is the most common mode for cheap clone ST-LINK adapters.

Why This Mode Exists

Many clone ST-LINK adapters do not have a working reset pin.

Mode B uses a guided connect-under-reset flow. The user manually touches C45 to GND when prompted, then releases it when prompted.

What Happens

1. The launcher starts OpenOCD.
2. OpenOCD asks you to connect C45 to GND.
3. The countdown runs.
4. OpenOCD asks you to release C45.
5. The target is examined and halted.
6. The dump or flash continues.

Tips

• Make the C45-to-GND contact reliable before starting.
• Keep SWDIO, SWCLK, and GND stable.
• Increase the countdown with T if needed.
• If the same error repeats, rebuild the physical connection before changing software settings.

Scooter-specific C45 location and hand/probe tricks belong in the model guides.
