hi we produced BBBW using beaglebone black wireless gerber files, so it calls, as it is.
However, any of board's LED does not turn on... ;(
When I check the voltage of the power pins of OSD3358, most of points shows almost abnormal voltage compared to normal board
In particular, the value of PGOOD is low.
The VDD_5V values are normal except connection part with TPS65217C ( This part cannot be confirmed because it is inside of the chip[osd3358].).
Is this connection problem between VDD_5V and TPS65217C in OSD3358? Or is there anything else I can check?
