| Error Message | Likely Cause | Solution (Latest Version) | | --- | --- | --- | | SWD initialization failed | Target not powered or wrong voltage | Use --vref-check to measure target voltage. Ensure 3.3V stable. | | Flash algorithm not found | Unknown chip or missing device file | Run update-device-db command to download latest family definitions. | | Programming timeout | Clock too high or long wires | Add --speed 500 (500 KHz) to slow down and stabilize. | | Verification failed at 0x... | Faulty connection or brownout | Use --verify slow for byte-by-byte check. Check GND wires. | | Secure access violation | RDP Level 1 active | Use --unlock reg0 (may require full chip erase). |
