Re: [Gumstix-users] I2C troubles with Overo/Pinto

Whoops - Too much coffee - I read the sentence:
  "My device does have a special supply IO pin which..." 
as
  "My device does *not* have a special supply IO pin which..."

My fault - Sorry and *thanks* for correcting me. In this case I think you
should be clear to go. 
In case it isn't working I agree it's beginning to get kind of strange. 

I can't remember: Are the pin-muxing of I2C normally set correct in the
standard Gumstix u-boot?

Secondly: Can you measure any activity on the I2C lines when trying to
access the sensors - Maybe you already stated this I can't remember...

Third: As suggested by Dave: Can you share a little more about your setup -
Sensor type, full schematics, etc. 

Sorry for not reading the post detailed enough and (@Dave) thanks again for
catching my mistake :-)
  Søren
