[Gumstix-users] 3D accelerometer on Gallop43

[jkoenig1987 <jon...@gm...>]

Hey all, has anyone had any success with reading the 3D accelerometer on the
Gallop43?  I was trying to run the bash script from
http://old.nabble.com/3D-Accelerometer-on-Palo35-advice--td27933777.html,
and even though the schematic shows the same accelerometer connections for
the Palo35 and Gallop43 boards, I get the error below:

root@overo:/# i2cget -y 3 0x1d 0x29 b
i2c_omap i2c_omap.3: controller timed out
Error: Read failed

Running i2cdetect seems to suggest that there's something wrong with the
entire bus, not just the accelerometer:

root@overo:/# i2cdetect -y -r 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- UU UU UU UU -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
root@overo:/# i2cdetect -y -r 3
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          i2c_omap i2c_omap.3: controller timed out
-- i2c_omap i2c_omap.3: controller timed out
-- i2c_omap i2c_omap.3: controller timed out
-- i2c_omap i2c_omap.3: controller timed out

... similar error for all addresses ...

The setup we're currently running is Overo Tide - Gallop43 - LCD, with the
most recent pre-built Palmtop image from
http://www.sakoman.com/feeds/omap3/glibc/images/overo/201011150741/.  I've
also tried the Console image and the pre-built factory image with the same
results.  Any thoughts on what to try next?

Thanks,
Jon Koenig
