I am working Video encoder adv7393.For configuration i am using TWI interface.


But the problem is i enabled      " <M> Blackfin TWI I2C  support "  in I2C Hardware Bus support  as module.After kernel booting i am giving modprobe for "i2c-bfin-twi.ko" in uclinux kernel.i install TWI sucessfully as module but I2C-0 node is not created in /dev directory.




What might be the problem.

a bus master driver is not the userspace device driver.  if you want the i2c /dev interface, then enable the driver for it.


I2C_CHARDEV -> I2C device interface
