Hi all,

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

Cheers,
Adrian.

Hi all,

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

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 GNU/Linux

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

bash-3.00# i2cdetect -y 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --

and bus #1

bash-3.00# i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

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
