  @YUUJI-INOUE I'm very confused by the voxl-px4.log file you attached. It is filled with a bunch of -- Reboot -- lines. Where do those lines come from? How did you generate voxl-px4.log? The only Accel #0 fail: TIMEOUT! I see is after a shutdown command has been issued to PX4. The Command failed is normal. The startup script attempts to do some auto-configuration by looking for devices that may not be attached to the drone and will produce those messages. Same with the i2c probe failed messages. The fact that you can fly in manual mode means that the IMU is fine.

  @chengyouzen , have you tried building OpenSSL from source (you should be able to do it directly on VOXL1)? That may be the only way..

  Thank you for your reply ,@Alex-Kushleyev .

  I am indeed using a 12V AC/DC adapter.
  ——————————————————————————————————

  I inspected the problematic motor and found that its mounting screws did not appear to be screwed into the windings, as shown in the picture below.

  Here are the results of voxl-esc_spin tests using two different power supplies:

  The 12V AC/DC adapter appears to be working fine (adapter_voxl-esc_spin_test_video) (adapter_voxl-esc_spin_test_result.txt

  However, the battery power test results show:

  Motor ID 0 is not working. (battery_voxl-esc_spin_test_video)

  The Average RPMs of Motor ID 0 detected by the voxl-esc tools is significantly lower than the other three motors. The image below is a partial screenshot of the data. Please click the link for the complete data.(battery_voxl-esc_spin_test_result.txt)

  Based on the above supplementary data, would you recommend that I send it for repair?

  Thank you very much!

  Re: open-vins mask file location

  Dear All,

  Regarding the previous post of @Jeremy-Frederick I'm still being unable to find the Open-VINS mask file location to apply different masks to each camera.

  Can you comment on that?

  Thank you in advance.

  Best Regards,
  Jacob

  @mkeyno You need to work with the PX4 community on this project, not ModalAI.
