Other Parts Discussed in Thread: TPS2052
I'm trying to figure out how the power is generated on this board, and it seems to me that there's something missing on the schematic set.
Let's say that I want to power the unit from the Target USB connector.
I put a jumper on JP1, pins 3,4.
On page 2, it seems that if I do that, I'm connecting TARGET_VBUS -> VBUS. From the schematics I've gotten, seems that is going to short pin 6 to pin 2 on U4, therefore rendering it useless for channel 2. Pin 7 will provide +5 to the BoosterPack connectors.
Where in these schematics is the +3V3 generated for the board? I see lots of connections for it, but they all seem to be loads, not supplies.
