MS4525: no sensor found. No INS backends available

ArduPlane
1

Hi

I’ve just tried installing ArduPlane on a BeagleBoneBlue using this guide:

but when running

sudo /home/debian/arduplane-3_8_3 -C udp:192.168.1.101:14550

I get this error:

MS4525: no sensor found
No INS backends available

Can anyone tell me what I can do?

Kind Regards
Jacob

Make sure you dont have an instance running already.
Check using sudo top for an existing arduplane running.
Make sure you have enough free space with df

3

I have free space and there is no other instance running.

4

In that case you might. need to build a new release for this new sensor

5

As far as I know I don’t have this sensor.

Also if I run ArduCopter instead I only get the error:

No INS backends available

This is both with pre-compiled and compiled versions of ArduPilot.

What I’m more confused about is, which Debian image should I be running?

I will give it a try

I’m currently running the 9.3 Debian Stretch IoT image.

Is this correct?

OK
I downloaded:
sudo wget http://bbbmini.org/download/blue/ArduPlane/arduplane-3_8_3
And I could start it no problem.

Here is how I build my image:

I followed your guide only using 2018-01-28 instead but get the same errors

Just ran rc_test_imu
and got all sorts of errors:

OK can you probe the sensors on the I2C bus ?
i2cdetect -r -y 2
I have this
