Use this page for mode:

[B] C45 / Clone ST-Link

This mode is for common clone ST-LINK adapters that usually do not have a working reset pin.

What Happens

The launcher starts OpenOCD and guides you through connect-under-reset:

1. connect C45 to GND when prompted;
2. wait for the countdown;
3. release C45 when prompted;
4. OpenOCD connects, examines, and halts the target;
5. the dump or flash continues.

Tips

• Make the C45-to-GND contact reliable before starting.
• Do not let the ST-LINK wires move during erase/write/verify.
• If the connection fails, increase the countdown timer with T.
• If the same error appears repeatedly, rebuild the physical connection before changing software settings.

Common Failure Cause

Most problems in this mode are not the firmware file or the scripts. They are unstable contact on SWDIO, SWCLK, GND, or C45.
