(so that everyone stays in touch)
Just did a few connections, add a few resistors, nothing more yet. It's in SVN.
I had to write a new resistor symbol (the one US-like, with a zigzag line). It's not perfect but should be enough for our needs.
Another symbol we need is an inductor - Kicad's is too large, and seems to have a width non-divisible by 50mil.
The power pins are "VAA" with a 0.5mil font size.
I also added a "Tolerance" field to resistors that depict their low tolerance.
I'm avoiding as much as possible to cross wires, so you might see many power pins all around (like VBAT_SYS). I think this makes design more readable.
We also have a lot of NC resistors, maybe we should get rid of some..
I'll resume my schematic work on PMU tomorrow. Until then :)
