PX4 Firmware Doesn't Read Pixhawk Sensors, thus No Calibration

I’m new to this so I would appreciate some help. I purchased a Radiolink Pixhawk 2.4.8 flight controller. I downloaded QGroundControl and installed the PX4 Pro Stable Release V1.13.2 firmware on my Pixhawk. When the firmware is installed, it doesn’t detect or read any sensors (Gyro, Accelerometer, Compass), thus calibration isn’t possible. For example, when I try to calibrate the accelerometer, I get the error - Calibration Failed: Reading Sensor.

I know that the hardware is okay as I can install Ardupilot fine and it reads all the sensors perfectly. The main reason I want to use PX4 is that when using Ardupilot firmware, there’s no option to calibrate ESC in the ‘Power’ section within the ‘Vehicle Setup’ section.
