Just wanted to point out a schematic error to LogicPD and others...

On the breakout board connector (J2) and on both connectors on the baseboard, the following pins are in the following order:

Quote:

SIM0_CLK
SIM0_VEN
SIM0_nDETECT
VREF_JTAG

But on the SOM schematic, they are in the following order:

Quote:

SIM0_CLK
SIM0_nDETECT
SIM0_VEN
VFEF_JTAG

Thus, SIM0_nDETECT and SIM0_VEN are switched everywhere in the baseboard and the breakoutboard. Its not a big deal unless you guys try to add a SIM connector to the baseboard, but just thought someone would want to know. I've been tearing my hair out (well not really that much) trying to figure out what was wrong w/ my software, when actually its just that I have things miswired b/c the schematic is mislabeled. I'm using these pins just as GPIO to interface separate hardware since I have no use for a SIM card.
