For thermal image acquisition I bought 2 RoBoard RM G-212. I am facing the following issues with the sensor:

1). The sensor is not communicating over the I2C protocol with the Arduino Nano microcomputer. I have tried compiling the attached code but have been unsuccessful so far. The error seems to be due to the i2cmaster.S file which is the assembler file. if I delete the file the code compiles successfully and we don't get the output on the serial monitor.

Error:-

2). The RoBoard Sensor/ Melexis MLX 90620 is not recognized by Raspberry Pi2. Perhaps it is the driver issue or I2C incompatibility.

Please advise.
