Recheck and adjust the PLL settings, ensuring that they are correctly configured for the intended operating frequency. Consider External Clock Generators : If the internal or external oscillators fail to provide stable performance, consider using an external clock generator to provide a more stable and accurate clock signal.

Conclusion

Inconsistent system clock performance in the GD32F103ZET6 microcontroller is often caused by improper clock source configuration, faulty external components, or power issues. By following the steps outlined above, you can systematically isolate the problem and apply the necessary fixes. Ensuring the correct clock source, proper PLL configuration, stable power supply, and environmental considerations will help restore consistent system clock performance.
