When I start my Stagecoach expansion board with multiple Overo Air COMs
connected, the GPIO21 LED for each Gumstix is inconsistent. Sometimes all
of the LEDs blink bright red (which I assume is the correct behavior). But
most of the time this LED stays about half way bright and does not blink
for the 'broken' COM. This happens for a different COM each time I power
up, and sometimes it happens for multiple COMs. I looked up the pin on the
data sheet and it corresponds to MMC3 Data 7. I re-imaged all of my COMs
already, and they're not booting from SDCard. Was wondering if someone
could help me out. I don't have the USB mini cable plugged in either, I
just have the ethernet cable plugged in.
