Downloading Processor Flash
As a sophisticated technique, you may clone all the processor reminiscence, packaging the firmware and configurations right into a single file. This technique is useful as you gained’t have to fret about firmware variations. Nonetheless, it requires extra software program like STM32CubeProgrammer.
