You don't seem to use it anyway. BTW, you must be using an old version of i2cdetect, as the slave address appears to be forced to 0x02 in the i2c-iop3xx driver (not a smart choice...) and i2cdetect does no more scan this address by default. > diff -uprN -X dontdiff linux-2.6.16.20/drivers/i2c/busses/i2c-iop3xx.h linux-2.6.16.20-iq80331/drivers/i2c/busses/i2c-iop3xx.h > --- linux-2.6.16.20/drivers/i2c/busses/i2c-iop3xx.h 2006-06-05 18:18:23.000000000 +0100 > +++ linux-2.6.16.20-iq80331/drivers/i2c/busses/i2c-iop3xx.h 2006-06-16 12:20:07.000000000 +0100 > @@ -85,6 +85,7 @@ > #define I2C_ERR 321 > #define I2C_ERR_BERR (I2C_ERR+0) > #define I2C_ERR_ALD (I2C_ERR+1) > +#define I2C_ERR_WRITEMYSAR (I2C_ERR+10) Please use tabs, not spaces, for alignment. -- Jean Delvare
