Hi, All:

I have five crazyflie2.0, there are two have a strange problem. when link the client, console print the following information
IMU:MPU9250 I2C connection [OK]
IMU:AK8963 I2C connection [FAIL]
IMU:LPS25H I2C connection [FAIL]

we know AK8963 and LPS25H also use the MPU9250's I2C interface, but why test fail ?

That is a bit strange indeed as the AK8963 is internally connected in the MPU9250. Maybe it is connected to the AUX i2c which the LPS25H also is and that the AUX bus is shorted or similar. Any visible damage to the LPS25H?
