I guess this is due to the differences between i2c and > smbus, and the hardware only handles the former correctly? Did you take into consideration that the smbus-call has (client, reg, val) as arguments while i2c_write has (val, reg), that is you have to swap the arguments? -- Pengutronix e.K. | Wolfram Sang | Industrial Linux Solutions | http://www.pengutronix.de/ |
