error with RK1430 board

We wanted to get some form of readable data from the IMU RKI1430, but the data shows up like this
315
317
395
345
349
315
As you see, there is only a single steady stream of data, instead of pitch roll and yaw separated by commas.I think that this is garbage data. Now, this is really pissing me off. And, its the same story when I use the sensor breakout pins separately. I changed the orientation i.e. moved it around 360 degrees but no change observed. Then tried movign it up and right fast and abrupt, but no change, so couldn’t be accelero data. I have no clue what magnetometer data looks like but this is crazy. I’m confused and the IMU was bought by my college for a project.
So, what do I try next?
