VDD_5V can act in 2 ways
Input or Output
the VDD_5V is an input from a 40 pin header if there is no DC adapter plugged in the barrel jack.
if there is a DC adapter plugged in barrel jack then VDD_5V is the output voltage on the 40 pin header can be used to connect any external devices.
now the error message says
Well, just remove one of the power flags.
I believe there can be only one power flag in a given net.
if i remove the pwr flag then i get
ErrType(3): Pin connected to some others pins but no pin to drive it
@ (6.700 in,2.300 in): Pin 1 (power_in) of component #PWR01 is not driven (Net 3).
Did you add Power flag to GND?
I would keep both flags as shown, I think the problem is both pins are power outputs. One should be power input.
Nick, could you give us your whole project? Including libraries you’re using.
ok give me 5 minutes please i will upload on server and share the link
Give me some time keruseykaryu may be an hour or so i shall clean all minor errors and warnings and then upload the final schematics
hi keruseykaryu
i have uploaded my schematics in the bellow path
https://drive.google.com/open?id=0B1rwVwGpi1IbMnZqMGxmT01zdVk
the are some 11 schematic files in flat hierarchal order
when i try to run ERC checker it throws around 40 errors
i am additionally explaining my schematic here:
if you see the schematic that i have attached here all the output voltages from the PMIC like VDD_1V8,VDD_CORE,VDD_MPU and so on i have used them as global label after all since in the real hardware it is just a copper wire running from this points to other devices now i am not sure how to use a power port and power flag if i use power flag only then how will the schematic know to connect different device requiring different voltages if i use power port only since you mentioned power ports are global the ERC complains about need for power flag
can you please help resolve this errors and let me know how to deal with different voltage outputs from the pmic do i need a power port to represent all the voltage values.
here you go keruseykaryu
please find the link which has one schematic and its associated library files
https://drive.google.com/folderview?id=0B1rwVwGpi1IbMnZqMGxmT01zdVk&usp=sharing
also you may get error related to global labels ignore then since they are used in some other schematic sheet
please help me with the errors and warning what it means i am bit confused why this error and warnings.
Regards
That’s why I said “net stubs” not “nets” 
A net stub is supposed to be connected just to one pin
Well, naturally I didn’t mean that net stubs are left as is. It’s just an easy way to have net labels created automatically based on the pin name a net stub is connected to. Then the user can copy and connect these named net stubs to other symbol pins. The advantage is that manual typing or copy-pasting is omitted.
Some of issues I have described in detail by PM.
In general, ERC errors are caused by poorly constructed symbols.
thanks keruseykaryu
i managed to resolve all warning and error i did this by
Regards
Nick
