Dear all, Hi,I am trying to add my own device to the msm i2c bus.The s5k3c1fx and ds2746 also connect to the same i2c bus,they work well,so I add the driver code according to them.But it cannot transmit data.Any suggestion is appreciated! Thank you in advance! Here is the dmesg,my linux kernel is 2.6.32.9. ... [ 6.213896] *scv_led* Probe.succ ...
