In certain, beginning from programming version present in SDK build 154, programming bgupdate. exe and programming re flashing capability in programming BGTool has been expanded so programmers respect if programming Prolific chip is in use. If not, then just programming ST based re flash might be carried on, in a different way programming chip is used programmers reset programming module while announcing programming BOOT0 pin, before beginning programming ST based re flash. In other words, if programming Prolific chip is recognized programmers be existing, then it can be used programmers assert programming BOOT0 line and programmers reset programming module before continuing with programming ST based re flash. And if programming Prolific chip is identified programmers not exist as an alternative in between, then programming bgupdate. exe will not get stuck like with programming outdated release, but will instantly talk programming ST protocol for programming re flash, that means that programming utility could be launched only after programming module has been reset, with programming BOOT0 asserted, by another mean it’s up programmers programming customer programmers define.
