[uClinux-dev] Is it possible to enable both hardware and GPIO I2C at the same time?

2009-04-09 Thread Allen Yang 
Hi,

Anybody here has the experience of enabling both hardware I2C and GPIO
I2C (the driver is i2c_gpio.c) in embedded Linux system.

I am trying to use two separate I2C busses in my system.

If I enable them separately (enable one, disable the other one), both
can work. However, if I enable them at the same time, the hardware I2C
cannot work. I got Adding I2C adapter failed error. I guess both
hardware and GPIO I2C are trying to use the same I2C adapter.

Anybody had this problem before? Any suggestion is highly appreciated.

Regards,

Allen Yang

properly written  configured i2c bus drivers have no problem running at the 
same time.  i have no experience with this specific one, but ive seen other 
hardware and software i2c busses used simultaneously.
