Firmware ver. 3.2 for VRBRAIN 4 and 4.5

Posted by emile on November 18, 2014 at 12:23pm in Software Framework Autopilot - IMU

We have just released the latest APM:Copter 3.2 firmware also for VRBRAIN 4 and VRBRAIN 4.5 boards.

You can follow the instructions on this page:

http://vrbrain.wordpress.com/download/version-3-2/

If you own a VRBRAIN 4.5 you can also take advantage of the new 3.2 with NuttX operating system. You just need to purchase or build a micro SD card reader to plug into your VRBRAIN.

You can purchase the expansion board here or you can build yourself one following this blog post: http://www.virtualrobotix.com/profiles/blogs/how-to-connect-sd-card-on-vrb-4-5-for-full-nutt-x-operations

Enjoy and fly safe!

    Hello!

    I tried the new 3.2 firmware on my VrBRain 4.5 without sd card reader and it works great.

    I made the autotune process and activated the EKF function with the Emile's correction on the baro.

    Pos hold is very impressive.

    Hello, be sure the board is correctly identified in Windows as VRBRAIN. 

    If you are using win 8, you need to disable signature check for driver install.

    If you use Win7 you should have no problems.

    To do this open device manager and check which COM+ is attached to.

    The Description of the COM port should be VRBrain.

    Then in Mission Planner before clicking on the firmware update page select the com port you have just checked in device manager.

    The first time is not necessary to disconnect the board, just try and click OK when prompted.

      Hello Pascal,

      Card is VRBrain 4.5, BootLoader is vrbrain45_bl.dfu.

      To upload .dfu file use Dfuse Demonstration and do not forget to remove the dfu jumper, then when it is done you can update your firmware with APM Mission Planner (you will have to jump number 9 plug -signal and ground - on the input rail (close to the telemetry plug)).

      Marc
