  I finally managed to compile the code from ubuntu and then transfering the executable to bbb.

  I'm trying to add a new driver to ardupilot, and it appears to not work with the BBBmini, when I try to obtain the i2c buse, I issue the following command _dev(hal.i2c_mgr->get_device(1, AP_RANGE_FINDER_TERARANGERI2C_DEFAULT_ADDR))

  the _dev variable is not initialized after that, do you have an idea?

  The i2c and spi buses management in ardupilot have changed quite a bit since the last 3 weeks.

  Hello Mirko, I checked with my development branch rebased with the latest master.
  Yes I use waf locally on the BBB
  
  the command
waf configure --board=bbbmini
has been issued after
git submodule update --init --recursive

and not before as stated in your wiki

and yes I use waf

  @Anemos Technologies

  Just checked that with latest master, all seems fine here. Do you use waf build system?

  Hello, After trying to install a new fresh build on my bbbmini, and trying to compile the ardupilot code, I got the following message : Could not find real exec path to arm-linux-gnueabihf-ar in path_list ['/home/debian/bin', '/usr/local/bin', '/usr/bin', '/bin', '/usr/local/games', '/usr/games', '/usr/bin']:
  (complete log in /home/debian/ardupilot/build/config.log)

  has anybody an idea where the problem could come from ?

  This is not a path problem, as the executable arm-linux-gnueabihf-ar is well present under /usr/bin

  Thanks

  To all BBBMINI ROV users: If you are using QGC with your BBBMINI the MS5837 pressure sensor parameter SCALED_PRESSURE2 is not grouped with the SCALED_PRESSURE parameter in the MAVLink Inspector window and is off the bottom of the MAVLink Inspector window parameter list incase you were wondering where it is.

  That's great Mirko, thanks very much going to the effort to do that for a very small minority of BBBmini users.

  Hi Mirko,

  Thank you for your efforts to integrate the MS5837 pressure sensor into the BBBMINI sensor suite.

  @Anemos Technologies,

  The MS5837 is a very accurate pressure sensor for use in underwater ROVs and its availability and use with the BBBMINI will help promote the use of the BBBMINI for ROV navigational control

  Hello all,

  What is the benefit of using this type of sensor compared to the one that is already working with bbbmini ?

  @Thomas

  Thanks for providing me a MS5837 sensor. First you are right, the sensor is not recognized by i2cdetect. But with i2cdump you can see that the MS5837 is answering to I2C requests from the Beagle Bone. I made some small modifications and the sensor is "accepted" as baro by arducopter. As the next the MS5611 driver has to be modified to report the right depth. I do not know if there is already a driver in ArduSub?

  Result: MS5837 can be used with BBBmini.
