: This happens due to voltage instability. If flashing in-circuit (without desoldering the chip), the motherboard may be drawing power away from the programmer. Desolder the chip or use an external power-supply tap. The CH341A black edition programmer operates at 5V,
Version 2.1.0.19 introduced a vast library of definitions. It handles standard 3.3V/5V flash chips alongside specialized hardware components that traditionally required industrial-grade programmers:
Before writing any new data, perform a Read and Save of the original firmware. It is best practice to read twice and compare the file hashes to ensure a perfect dump. Hardware Considerations: The 3.3V vs 5V Issue This link or copies made by others cannot be deleted
