Cause: Flash write mismatch, often due to unstable power supply or too high a baud rate.
Fix: Reduce baud rate to 9600 or 19200. Ensure the target board is powered by a stable 3.3V/5V source (not solely from the serial adapter’s VCC pin).
Cause: Corrupted configuration file or incompatible Windows version (rare on Win10/11, common on WinXP).
Fix: Delete isp_config.ini (if present in the same folder) and relaunch. Run in Windows 7 compatibility mode.
