Hello, in the documentation i found at http://ww2.cs.fsu.edu/~rosentha/linux/2.6.26.5/docs/DocBook/kernel-api/re1222.html the following sentence: "Note that using this function requires that the client's adapter support the I2C_FUNC_SMBUS_READ_BLOCK_DATA functionality. Not all adapter drivers support this; its emulation through I2C messaging relies on a specific mechanism (I2C_M_RECV_LEN) which may not be implemented." The second sentence says that the mechanism I2C_M_RECV_LEN is not all over implemented. How i can figure out whether this mechanism will be provided of my driver? What is the alternative of using the function i2c_smbus_read_block_data? Thanks a lot for your support, Michael Post -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
