The example code works fine on Mega2560, but it won't work when integrated in my own code.

At first I was lured into debug mpu_init() because it always return error code until the return value in example is printed out.

The solution for now is give raw data from register to Raspberry Pi to calculate orientation.
Thank you for reply.
