Pixhawk 2.4.8 sensor not recognized

I have a pixhawk 2.4.8 with STM32 F427 VIT6. When I installed px4 fmuv3 firmware using qground control software the accelerometer and gyroscopes were not recognized. It is not an hardware issue because they were getting recognized when I installed the fmuv3 from ardupilot. Can anyone share the reason or their experience with a similar issue.
