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