Hi all,
Just a quick one, does any-one know if the i2c-mpc i2c driver will
function on a Freescale MPC8347?
Cheers,
Adrian.

Seems to work fine on the MPC8349E-MDS-PB.
I believe one of the engineers just installed the lm-sensors
i2c tools and they worked fine, i.e., the i2c driver that
is built by default in the Denx kernel and LTIB kernel
works.
I know I've used the i2c tools without trouble.
If its any use, here's what appears to be running on the
board now (ELDK 4.0 based I believe ...)
bash-3.00# uname -a
Linux cobralab1 2.6.18-rc2 #1 Tue Aug 8 13:04:42 PDT 2006 ppc ppc ppc

Here's the output from an MPC8349E-MDS-PB bus #0

I've hooked up an AD7998 I2C eval board to bus #1
at address 21h. Normally you'd only see the EEPROM
at 50h.
Cheers,
Dave
