Hello all, sorry for the double post (i've posted this question on another thread of schematic request).
i'm working on this board that doesn't have any power at all, the usb-c ammeter stay off and the thermal camera doesn't show anything heating up.
I have no experience with usb-c powered boards, but I know there's a thunderbolt chip negotiating with the power supply and the power management chip.
Could it be the intel jhl8040r thunderbolt controller (U7101) to be dead?
Probing the caps around it i didn't find anything shorted.
Can someone give me some hint to start hunting for the probable issue with this board please?
I know I didn't give many informations but judging by the fact that neither the usb-c meter is turning on made me thing about the thunderbolt chip.
Thanks to anyone that will contribute
