Thanks for your answer.
I confirm, I’m using the starter kit.
I have to admit that unsoldering the resistor is not very reassuring. I suppose the processor won’t like it too much if we disable the protections.
I just checked the voltage with the new 19V regulator, and it turns out that one is very bad (I observed spicks of more than 1.5V downwards).
So maybe the solution is rather to find a good voltage regulator.
Is there any you know works well?
Otherwise, what exactly are the requirements? Is 12V good (easier to find) or should I go for 19V?
And what are exactly the constraints on the maximal ondulation allowed (the protection circuit is called dV/dt, but then only an absolute drop of -0.5V is mentionned.
Thanks a lot in advance
Best regards
Felix
