Vibration Dampened Board Sensors (lsm303d,l3gd20 ) are not running
I have recently purchased a new pixhawk2.1.
I power the Cube from the power brick mini and connect it to MP via usb.
I load FW Arducopter FW3.5.7.
In the Full Parameters List , i see the parameters INS_ACC2_ID INS_ACC3_ID have values ZERO.
So i thought the Second IMU is missing .
In order to test the sensors i re-flash the Cube with ArduCopter3.4.6.
In MP>>Terminal>>nsh>> i run command “lsm303d start”. I get the following Errors:
LSM303D probe failed
LSM303D: SPI init failed
LSM303D : Driver start failed
and Running the command : nsh>>"l3gd20 start ". I get the following Errors:
L3GD20 probe failed
L3GD20 : Driver start failed
I have changed different Arducopter firmwares.
Change different Vehicle Types but with the same Problem.
Kindly Help. Because i am observing this Problem in 7 Cubes.
