Oh, just come out of reset quickly and switch off the FETs. Before the PMU has left reset, it won't listen to I2C anyway, so everything that could be trouble (AUTO, maybe BAT) needs to be controlled directly anyway. > And VB_SYS has the big advantage it > is already "mixed" from the power sources. Yeah ! :-) > That's a whole other (zombie) battle :-) Let's see how the next round of that one will go, in light of the case for the MPU getting stronger. It actually went pretty much like we predicted: we couldn't tell any specific problem the MPU would solve, but we were sure that it would eventually appear. And so it did, even earlier than we throught. Cheers, Werner
