Hi

im testing on the EK of 9x35 .
i am trying to communicate with TWI over linux.
under /sys/bus/i2c/devices i can find the interfaces the board provides.
but if i try to communicate with some i only get error .

my implementation as follows:

#define I2C_PATH "/sys/devices/platform/i2c-gpio.0/i2c-0"
fd = open(I2C_PATH, O_RDWR);

this call fails.
i tried to chmod but nothing got better.

Anybody can help me to get i2c work , perhapts one who got it on another board.

Thanks in advice.
