Hi Aditya,
Could you try out with additional flag : "*I2C_M_IGNORE_NAK*"
You need to change code like:
msg.flags = client->flags & I2C_M_TEN *|* *I2C_M_IGNORE_NAK*;
in *i2c_master_send* and *i2c_master_recv* functions of i2c-core.c file.
Fore more info:
*/http://lxr.linux.no/#linux+v2.6.37.2/Documentation/i2c/i2c-protocol/*
let me know this experiment works with you or not.
Regards,
Jignesh
