Hi,
I have a schematic with an MCU that I had a net name used on multiple sheets connected to a pin. I erased the pin connection, then connected it to another pin, and found that the pin had maintained its net name even though there is NO NET connected to it. An airwire on the board confirms this connection.
I just recently upgraded from Eagle 6.1 to 6.2 after having other issues.
I fixed it by opening up the XML and removing the offending net from the MCU pin name in the .sch file and the offending pad connection on the .brd file.
Schematic:
<net name="AN_+12V" class="0">
<segment>
<pinref part="MPU" gate="G$1" pin="PF1(ADC1)"/>
<pinref part="MPU" gate="G$1" pin="PF1(ADC1)"/>
</segment>
</net>
Board:
<contactref element="MPU" pad="60"/>
Better (i.e., non-XML) workarounds would be appreciated.
Best,
Brad
